Introduction
This Service Bulletin contains Oxygen Sensor (O2S) Monitor threshold values for all models from
1996 to 2003 and some 2004 models. Starting in 2004, the O2S Monitor threshold values can be
found in the repair manual. These values are used when analyzing the O2S test results to
determine the O2S condition.
Applicable Vehicles ^
All 1996 - 2003 model year Toyota vehicles.
^ 2004 model year Corolla, ECHO, Matrix and Sienna vehicles.
^ 2004 model year Scion xA and xB vehicles.
Function Description
Checking O2S Test Results
To view O2S test results, the O2S Monitor must be completed and the test results must be
checked within the same key cycle. If the ignition key is cycled OFF, the O2S test results will be set
to the minimum or maximum limits, and all test results will be erased. The O2S test results are
stored in the ECU (SAE term: Powertrain Control Module/PCM) when the monitor is completed.
The test results are static and will not change once the monitor is complete.
The process for checking 02S test results is described in the following three basic steps:
1. Completing the O2S Readiness Monitor.
2. Accessing O2S Test Results.
3. Comparing O2S Test Results to Failure Thresholds.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

Terminal Identification
Reference
DLC3 INSPECTION
The vehicle's ECM uses the ISO 9141-2 communication protocol. The terminal arrangement of
DLC3 complies with SAE J1962 and matches the ISO 9141-2 format.
HINT If your display shows "UNABLE TO CONNECT TO VEHICLE" when you have connected the
cable of the OBD II scan tool or TOYOTA hand-held tester to DLC3, turned the ignition switch ON
and operated the scan tool, there is a problem on the vehicle side or tool side. If communication is normal when the tool is connected to another vehicle, inspect DLC3 on the
original vehicle.
- If communication is still not possible when the tool is connected to another vehicle, the problem is
probably in the tool itself, so consult the Service Department listed in the tool's instruction manual.

Air Flow Meter/Sensor: Description and Operation
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a
platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow
meter works on the principle that the hot wire and thermistor located in the intake air bypass of the
housing detect any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot
wire. This current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set
temperature.

Shift Solenoid: Description and Operation
DESCRIPTION
Shift Solenoid 1-2
The ECM uses signals from the vehicle speed sensor and crankshaft position sensor to detect the
actual gear position (1st, 2nd, 3rd or O/D gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect
mechanical trouble of the shift solenoid valves, valve body or automatic transaxle (clutch, brake or
gear etc.).
Shifting from 1st to O/D is performed in combination with ON and OFF of the shift solenoid valves
No.1 and No.2 controlled by ECM. If an open or short circuit occurs in either of the shift solenoid
valves, the ECM controls the remaining normal shift solenoid valve to allow the vehicle to be
operated smoothly (Fail safe function).
Fail Safe Function:
If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift
solenoid ON and OFF to shift to the gear positions shown. The ECM also turns the shift solenoid
valve SL OFF at the same time. If both solenoids are malfunctioning, hydraulic control cannot be
performed electronically and must be done manually.
Shift Solenoid Valve SL
The ECM uses the signals from the Throttle position sensor, Air-flow meter and Crankshaft position
sensor to monitor the engagement condition of the lock-up clutch.

Overdrive Indicator Lamp: Description and Operation
O/D Main Switch & O/D Off Indicator Light
The O/D main switch contacts go open when the switch is pushed in and go closed when it is
pushed out. If O/D main switch is at OFF position, the O/D OFF indicator light lights up, and the
ECM prohibits shifting overdrive.
While driving uphill with cruise control activated, in order to minimize gear shifting and provide
smooth cruising overdrive may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels
overdrive shifting until these signals are discontinued.

Oxygen Sensor: Description and Operation
DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a
three-way catalytic converter is used, but for the most efficient use of the three-way catalytic
converter, the air-fuel ratio must be precisely controlled so that it is always close to the
stoichiometric air-fuel ratio.
The oxygen sensor has the characteristic whereby its output voltage changes suddenly in the
vicinity of the stoichiometric air-fuel ratio. This is used to detect the oxygen concentration in the
exhaust gas and provide feedback to the computer for control of the air-fuel ratio.
When the air-fuel ratio becomes LEAN, the oxygen concentration in the exhaust increases and the
oxygen sensor informs the ECM of the LEAN condition (small electromotive force: <0.45 V).
When the air-fuel ratio is RICHER than the stoichiometric air-fuel ratio the oxygen concentration in
the exhaust gas in reduced and the oxygen sensor informs the ECM of the RICH condition (large
electromotive force: > 0.45 V).
The ECM judges by the electromotive force from the oxygen sensor whether the air-fuel ratio is
RICH or LEAN and controls the injection time accordingly. However, if malfunction of the oxygen
sensor causes output of abnormal electromotive force, the ECM is unable to perform accurate
air-fuel ratio control. The oxygen sensors include a heater which heats the zirconia element. The
heater is controlled by the ECM. When the intake air volume is low (the temp. of the exhaust gas is
low) current flows to the heater to heat the sensor for accurate oxygen concentration detection.

Air Flow Meter/Sensor: Description and Operation
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a
platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow
meter works on the principle that the hot wire and thermistor located in the intake air bypass of the
housing detect any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot
wire. This current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set
temperature.

Intake Air Temperature Sensor: Description and Operation
The intake air temperature sensor is built into the air cleaner cap and senses the intake air
temperature. A thermistor built in the sensor changes the resistance value according to the intake
air temperature.
Figure 1
The lower the intake air temperature, the greater the thermistor resistance value, and the higher
the intake air temperature, the lower the thermistor resistance value.
The intake air temperature sensor is connected to the ECM. The 5 V power source voltage in the
ECM is applied to the intake air temperature sensor from the terminal THA via a resistor R. That is,
the resistor R and the intake air temp. sensor are connected in series. When the resistance value
of the intake air temp. sensor changes in accordance with changes in the intake air temperature,
the potential at terminal THA also changes. Based on this signal, the ECM increases the fuel
injection volume to improve driveability during cold engine operation.

Intake Air Temperature Sensor: Description and Operation
The intake air temperature sensor is built into the air cleaner cap and senses the intake air
temperature. A thermistor built in the sensor changes the resistance value according to the intake
air temperature.
Figure 1
The lower the intake air temperature, the greater the thermistor resistance value, and the higher
the intake air temperature, the lower the thermistor resistance value.
The intake air temperature sensor is connected to the ECM. The 5 V power source voltage in the
ECM is applied to the intake air temperature sensor from the terminal THA via a resistor R. That is,
the resistor R and the intake air temp. sensor are connected in series. When the resistance value
of the intake air temp. sensor changes in accordance with changes in the intake air temperature,
the potential at terminal THA also changes. Based on this signal, the ECM increases the fuel
injection volume to improve driveability during cold engine operation.

Coolant Temperature Sensor/Switch (For Computer): Description and Operation
A thermistor that is built into the engine coolant temperature sensor changes the resistance value
according to the engine coolant temperature.
The lower the engine coolant temperature sensor, the greater the thermistor resistance value, and
the higher the engine coolant temperature sensor temperature, the lower the thermistor resistance
value.
The engine coolant temperature sensor is connected to the ECM. The 5 V power source voltage in
the ECM is applied to the engine coolant temperature sensor from the terminal THA via a resistor
R. That is, the resistor R and the engine coolant temperature sensor are connected in series.
When the resistance value of the engine coolant temperature sensor changes in accordance with
changes in the engine coolant temperature, the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to improve driveability during cold engine
operation.
If the ECM detects the DTC P0115, it operates fail safe function in which the engine coolant
temperature is assumed to be 80°C (176°F).

Wheel Speed Sensor: Description and Operation
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the appropriate signals to the ECU. These
signals are used to control the ABS system. The front and rear rotors each have 48 serrations.
When the rotors rotate, the magnetic field emitted by the permanent magnet in the speed sensor
generates an AC voltage. Since the frequency of this AC voltage changes in direct proportion to the
speed of the rotor, the frequency is used by the ECU to detect the speed of each wheel.
Fail safe function:
If trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS relay and prohibits
ABS control.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

Air Flow Meter/Sensor: Description and Operation
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a
platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow
meter works on the principle that the hot wire and thermistor located in the intake air bypass of the
housing detect any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot
wire. This current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set
temperature.

Then the ECM compares the engagement condition of the lock-up clutch with the lock-up schedule
in the ECM memory to detect mechanical trouble of the shift solenoid valve SL, valve body, torque
converter clutch or automatic transaxle (clutch, brake or gear etc.).
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic
pressure acting on the lock-up relay valve, which then controls operation of the lock-up clutch.
Fail Safe Function: If the ECM detects a malfunction, it turns the shift solenoid valve SL OFF.

Air Flow Meter/Sensor: Description and Operation
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a
platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow
meter works on the principle that the hot wire and thermistor located in the intake air bypass of the
housing detect any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot
wire. This current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set
temperature.

Ground Points
The ground points circuit diagram shows the connections from all major parts to the respective

Knock Sensor: Description and Operation
The knock sensor is fitted to the cylinder block to detect engine knocking. This sensor contains a
piezoelectric element which generates a voltage when it becomes deformed, which occurs when
the cylinder block vibrates due to knocking. If engine knocking occurs, ignition timing is retarded to
suppress it.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

System Outline
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is

Camshaft Position Sensor: Description and Operation
The Camshaft position sensor (G signal) consists of a signal plate and pick up coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust
camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil
change, causing fluctuations in the magnetic field and generating an electromotive force in the pick
up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor
generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft
angle and the engine speed by the NE signals.

Shift Indicator: Description and Operation Electronically Controlled Transmission and A/T Indicator
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is no continuous to either No.1 or No.2 solenoid.
2. LOCK-UP OPERATION
When the engine control module judges from each signal that lock-up operation conditions have
been met, current flows from TERMINAL SL of the Engine Control Module to TERMINAL 3 of the
Electronically Controlled Transmission solenoid to GROUND, causing continuity to the lock-up
solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (stop light SW on) when driving in lock-up condition, a signal is
input to TERMINAL BK of the engine control module. The engine control module operates and
continuous to the lock-up solenoid is cut.

Knock Sensor: Description and Operation
The knock sensor is fitted to the cylinder block to detect engine knocking. This sensor contains a
piezoelectric element which generates a voltage when it becomes deformed, which occurs when
the cylinder block vibrates due to knocking. If engine knocking occurs, ignition timing is retarded to
suppress it.
Page 1521
Finding A Short Circuit
a. Remove the blown fuse and disconnect all loads of the fuse. b. Connect a test light in place of
the fuse. c. Establish conditions in which the test light comes on.
Example: A- Ignition SW ON B- Ignition SW and SW 1 ON C- Ignition SW, SW 1 and Relay ON
(Connect the Relay) and SW 2 OFF (or Disconnect SW 2)
d. Disconnect and reconnect the connectors while watching the test light.
The short lies between the connector where the test light stays lit and the connector where the light
goes out.
e. Find the exact location of the short by lightly shaking the problem wire along the body.
CAUTION:
a. Do not open the cover or the case of the ECU unless absolutely necessary. (If the IC terminals
are touched, the IC may be destroyed by
static electricity.)
b. When replacing the internal mechanism (ECU part) of the digital meter, be careful that no part of
your body or clothing comes in contact
with the terminals of leads from the IC, etc. of the replacement part (spare part)

Knock Sensor: Description and Operation
The knock sensor is fitted to the cylinder block to detect engine knocking. This sensor contains a
piezoelectric element which generates a voltage when it becomes deformed, which occurs when
the cylinder block vibrates due to knocking. If engine knocking occurs, ignition timing is retarded to
suppress it.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

Overdrive Switch: Description and Operation
O/D Main Switch & O/D Off Indicator Light
The O/D main switch contacts go open when the switch is pushed in and go closed when it is
pushed out. If O/D main switch is at OFF position, the O/D OFF indicator light lights up, and the
ECM prohibits shifting overdrive.
While driving uphill with cruise control activated, in order to minimize gear shifting and provide
smooth cruising overdrive may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels
overdrive shifting until these signals are discontinued.

Starter Signal: Testing and Inspection
Starter Signal Circuit
CIRCUIT DESCRIPTION
When the engine is cranked, the intake air flow is slow, so fuel vaporization is poor. A rich mixture
is therefore necessary in order to achieve good startability. While the engine is being cranked, the
battery positive voltage is applied to terminal STA of the ECM. The starter signal id mainly used to
increase the fuel injection volume for the starting injection control and after-start injection control.

INSPECTION PROCEDURE
HINT: This diagnostic chart is based on the premise that the engine is cranked normally. If the
engine is not ¢4mcranked, proceed to the problem symptoms table.

Transmission Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

System Outline
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is

The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Coolant Temperature Sensor/Switch (For Computer): Description and Operation
A thermistor that is built into the engine coolant temperature sensor changes the resistance value
according to the engine coolant temperature.
The lower the engine coolant temperature sensor, the greater the thermistor resistance value, and
the higher the engine coolant temperature sensor temperature, the lower the thermistor resistance
value.
The engine coolant temperature sensor is connected to the ECM. The 5 V power source voltage in
the ECM is applied to the engine coolant temperature sensor from the terminal THA via a resistor
R. That is, the resistor R and the engine coolant temperature sensor are connected in series.
When the resistance value of the engine coolant temperature sensor changes in accordance with
changes in the engine coolant temperature, the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to improve driveability during cold engine
operation.
If the ECM detects the DTC P0115, it operates fail safe function in which the engine coolant
temperature is assumed to be 80°C (176°F).

Transmission Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

The "Current Flow Chart" images, describes which parts each power source (fuses, fusible links,
and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when
battery power is supplied to each system are explained. Since all System Circuit diagrams start
from the power source, the power source system must be fully understood.
Current Flow Chart
The chart shows the route by which current flows from the battery to each electrical source (Fusible
Link, circuit Breaker, Fuse, etc.) and other parts.

Vehicle Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Overdrive Switch: Description and Operation
O/D Main Switch & O/D Off Indicator Light
The O/D main switch contacts go open when the switch is pushed in and go closed when it is
pushed out. If O/D main switch is at OFF position, the O/D OFF indicator light lights up, and the
ECM prohibits shifting overdrive.
While driving uphill with cruise control activated, in order to minimize gear shifting and provide
smooth cruising overdrive may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels
overdrive shifting until these signals are discontinued.

Fuel Pressure Release: Service and Repair
GENERAL PRECAUTIONS
1. Before working on the fuel system, disconnect the negative (-) terminal cable from the battery.
HINT: Any diagnostic trouble code retained by the ECM will be erased when the battery negative
(-) terminal removed from The battery. Therefore, if necessary, read the diagnostic trouble code(s)
before removing the negative (-) terminal cable from the battery.
2. Do not smoke or work near an open flame when working on the fuel system.
FUEL PRESSURE RELEASE PROCEDURE
WHEN DISCONNECTING THE HIGH PRESSURE FUEL LINE, A LARGE AMOUNT OF
GASOLINE WILL SPILL OUT, SO OBSERVE THESE PROCEDURES:
- Put a container under the connection.
- Slowly loosen the connection.
- Disconnect the connection.
- Plug the connection with a rubber plug.
WHEN CONNECTING THE FLARE NUT OR UNION BOLT ON THE HIGH PRESSURE PIPE
UNION, OBSERVE THESE PROCEDURES: Union Bolt Type:
- Always use a new gasket.
- Tighten the union bolt by hand.
- Tighten the union bolt to the specified torque.

Coolant Temperature Sensor/Switch (For Computer): Description and Operation
A thermistor that is built into the engine coolant temperature sensor changes the resistance value
according to the engine coolant temperature.
The lower the engine coolant temperature sensor, the greater the thermistor resistance value, and
the higher the engine coolant temperature sensor temperature, the lower the thermistor resistance
value.
The engine coolant temperature sensor is connected to the ECM. The 5 V power source voltage in
the ECM is applied to the engine coolant temperature sensor from the terminal THA via a resistor
R. That is, the resistor R and the engine coolant temperature sensor are connected in series.
When the resistance value of the engine coolant temperature sensor changes in accordance with
changes in the engine coolant temperature, the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to improve driveability during cold engine
operation.
If the ECM detects the DTC P0115, it operates fail safe function in which the engine coolant
temperature is assumed to be 80°C (176°F).

Starter Signal: Description and Operation
Starter Signal When the engine is cranked, the intake airflow is slow, so fuel vaporization is poor A
rich mixture is therefore necessary in order to achieve good startability.
While the engine is being cranked, the battery positive voltage is applied to terminal STA of the
ECM.
The starter signal is mainly used to increase the fuel injection volume for the starting injection
control and after-start injection control.

System Outline
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is

Camshaft Position Sensor: Description and Operation
The Camshaft position sensor (G signal) consists of a signal plate and pick up coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust
camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil
change, causing fluctuations in the magnetic field and generating an electromotive force in the pick
up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor
generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft
angle and the engine speed by the NE signals.

Air Flow Meter/Sensor: Description and Operation
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a
platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow
meter works on the principle that the hot wire and thermistor located in the intake air bypass of the
housing detect any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot
wire. This current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set
temperature.

Vehicle Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Intake Air Temperature Sensor: Description and Operation
The intake air temperature sensor is built into the air cleaner cap and senses the intake air
temperature. A thermistor built in the sensor changes the resistance value according to the intake
air temperature.
Figure 1
The lower the intake air temperature, the greater the thermistor resistance value, and the higher
the intake air temperature, the lower the thermistor resistance value.
The intake air temperature sensor is connected to the ECM. The 5 V power source voltage in the
ECM is applied to the intake air temperature sensor from the terminal THA via a resistor R. That is,
the resistor R and the intake air temp. sensor are connected in series. When the resistance value
of the intake air temp. sensor changes in accordance with changes in the intake air temperature,
the potential at terminal THA also changes. Based on this signal, the ECM increases the fuel
injection volume to improve driveability during cold engine operation.

Igniter: Description and Operation
CIRCUIT DESCRIPTION
A DIS (Direct Ignition System) has been adopted, The DIS improves the ignition timing accuracy,
reduces high-voltage loss and enhances the overall reliability of the ignition system by eliminating
the distributor. The DIS is a 2-cylinder simultaneous ignition system which ignites 2 cylinders
simultaneously with 1 ignition coil. In the 2-cylinder simultaneous ignition system, each of the 2
spark plugs is connected to the end of the secondary winding, High voltage generated in the
secondary winding is applied directly to the 2 spark plugs. The sparks of the 2 spark plugs pass
simultaneously from the center electrode to the ground electrode. The ECM determines ignition
timing and outputs the ignition signals (IGT) for each cylinder. Based on IGT signals, the power
transistors in the igniter cuts off the current to the primary coil in the ignition coil is supplied
simultaneously to the two spark plugs via the high-tension cords that are connected to the both
ends of the secondary coil. At the same time, the igniter also sends an ignition confirmation signal
(IGF) as a fail-safe measure to the ECM.

Camshaft Position Sensor: Description and Operation
The Camshaft position sensor (G signal) consists of a signal plate and pick up coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust
camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil
change, causing fluctuations in the magnetic field and generating an electromotive force in the pick
up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor
generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft
angle and the engine speed by the NE signals.

Igniter: Description and Operation
CIRCUIT DESCRIPTION
A DIS (Direct Ignition System) has been adopted, The DIS improves the ignition timing accuracy,
reduces high-voltage loss and enhances the overall reliability of the ignition system by eliminating
the distributor. The DIS is a 2-cylinder simultaneous ignition system which ignites 2 cylinders
simultaneously with 1 ignition coil. In the 2-cylinder simultaneous ignition system, each of the 2
spark plugs is connected to the end of the secondary winding, High voltage generated in the
secondary winding is applied directly to the 2 spark plugs. The sparks of the 2 spark plugs pass
simultaneously from the center electrode to the ground electrode. The ECM determines ignition
timing and outputs the ignition signals (IGT) for each cylinder. Based on IGT signals, the power
transistors in the igniter cuts off the current to the primary coil in the ignition coil is supplied
simultaneously to the two spark plugs via the high-tension cords that are connected to the both
ends of the secondary coil. At the same time, the igniter also sends an ignition confirmation signal
(IGF) as a fail-safe measure to the ECM.

Camshaft Position Sensor: Description and Operation
The Camshaft position sensor (G signal) consists of a signal plate and pick up coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust
camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil
change, causing fluctuations in the magnetic field and generating an electromotive force in the pick
up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor
generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft
angle and the engine speed by the NE signals.

Power Source
The "Current Flow Chart" images, describes which parts each power source (fuses, fusible links,
and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when
battery power is supplied to each system are explained. Since all System Circuit diagrams start
from the power source, the power source system must be fully understood.

no continuous to either No.1 or No.2 solenoid.
2. LOCK-UP OPERATION
When the engine control module judges from each signal that lock-up operation conditions have
been met, current flows from TERMINAL SL of the Engine Control Module to TERMINAL 3 of the
Electronically Controlled Transmission solenoid to GROUND, causing continuity to the lock-up
solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (stop light SW on) when driving in lock-up condition, a signal is
input to TERMINAL BK of the engine control module. The engine control module operates and
continuous to the lock-up solenoid is cut.

Introduction
A battery in a stored vehicle is subject to conditions that can reduce its performance and life. These
conditions include storage period, temperature, parasitic drain, and battery load. Because of these
factors, battery inspection and maintenance are required in order to ensure proper operation and
optimal battery life.
As a matter of policy, Toyota does not provide battery warranty coverage for discharged and/or
failed batteries due to lack of maintenance. It is the dealer's responsibility to maintain the specified
State of Charge (SOC) of the vehicle's battery while in stock and assure proper State of Charge
(SOC) at delivery.
To eliminate customer service concerns due to an undercharged battery during the first few weeks
of ownership, all dealers should check battery State of Charge (SOC) and recharge, if necessary,
within 48 hours of delivery to customers.
Applicable Vehicles

Idle Speed/Throttle Actuator - Electronic: Description and Operation
The rotary solenoid type IAC valve is located on the throttle body and intake air bypassing the
throttle valve is directed to the IAC valve through a passage.
In this way the intake air volume bypassing the throttle valve is regulated, controlling the engine
speed.
The ECM operates only the IAC valve to perform idle-up and provide feedback for the target idling
speed.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

Shift Solenoid: Description and Operation
DESCRIPTION
Shift Solenoid 1-2
The ECM uses signals from the vehicle speed sensor and crankshaft position sensor to detect the
actual gear position (1st, 2nd, 3rd or O/D gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect
mechanical trouble of the shift solenoid valves, valve body or automatic transaxle (clutch, brake or
gear etc.).
Shifting from 1st to O/D is performed in combination with ON and OFF of the shift solenoid valves
No.1 and No.2 controlled by ECM. If an open or short circuit occurs in either of the shift solenoid
valves, the ECM controls the remaining normal shift solenoid valve to allow the vehicle to be
operated smoothly (Fail safe function).
Fail Safe Function:
If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift
solenoid ON and OFF to shift to the gear positions shown. The ECM also turns the shift solenoid
valve SL OFF at the same time. If both solenoids are malfunctioning, hydraulic control cannot be
performed electronically and must be done manually.
Shift Solenoid Valve SL
The ECM uses the signals from the Throttle position sensor, Air-flow meter and Crankshaft position
sensor to monitor the engagement condition of the lock-up clutch.

O/D Cancel Signal Circuit
Overdrive Switch: Testing and Inspection O/D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving uphill with cruise control activated, in order to minimize gear shifting and provide
smooth cruising O/D may be prohibited temporarily under some conditions. The cruise control ECU
sends O/D cut signals to the ECM as necessary and the ECM cancels O/D shifting until these
signals are discontinued.

Brakes - Pad Clicking Noise
Brake Pad: Customer Interest Brakes - Pad Clicking Noise
BRAKES BR004-00
October 20, 2000
Title: BRAKE PAD CLICKING NOISE
Models: '90- '00 All Models
Introduction A clicking type noise may be noticed when first applying the brakes after changing
vehicle travel direction (Drive/Forward to Reverse, Reverse to Drive/Forward). This is a normal
noise caused by the required brake pad-to-caliper clearances. When the direction of travel is
changed, the brake pads may "shift" towards the new direction of travel. When the brake pad
contacts the caliper, a clicking noise may be heard.
To minimize this clicking noise, a disc brake caliper grease has been made available for use during
brake service/maintenance operations. Under normal usage conditions this grease should be
effective for a period of 6 months to 1 year.
Applicable Vehicles ^
1990 - 2000 model year Toyota vehicles, all models.

CIRCUIT DESCRIPTION
When the brake pedal is on depressed, battery positive voltage normally applies through the STOP
fuse and stop light switch to terminal STP- of the ECU and the ECU turns the cruise control off. A
fail-safe function is provided so that cancel functions normally, even if there is a malfunction in the
stop light signal circuit. If the harness connected to terminal STP- has an open circuit, terminal
STP- will have battery positive voltage and the cruise control will be turned off. Also, when the
brake is on, the magnetic clutch is cut mechanically by the stop light switch, turning the cruise
control off.

Coolant Temperature Sensor/Switch (For Computer): Description and Operation
A thermistor that is built into the engine coolant temperature sensor changes the resistance value
according to the engine coolant temperature.
The lower the engine coolant temperature sensor, the greater the thermistor resistance value, and
the higher the engine coolant temperature sensor temperature, the lower the thermistor resistance
value.
The engine coolant temperature sensor is connected to the ECM. The 5 V power source voltage in
the ECM is applied to the engine coolant temperature sensor from the terminal THA via a resistor
R. That is, the resistor R and the engine coolant temperature sensor are connected in series.
When the resistance value of the engine coolant temperature sensor changes in accordance with
changes in the engine coolant temperature, the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to improve driveability during cold engine
operation.
If the ECM detects the DTC P0115, it operates fail safe function in which the engine coolant
temperature is assumed to be 80°C (176°F).
Brakes - Pad Clicking Noise
Brake Pad: All Technical Service Bulletins Brakes - Pad Clicking Noise
BRAKES BR004-00
October 20, 2000
Title: BRAKE PAD CLICKING NOISE
Models: '90- '00 All Models
Introduction A clicking type noise may be noticed when first applying the brakes after changing
vehicle travel direction (Drive/Forward to Reverse, Reverse to Drive/Forward). This is a normal
noise caused by the required brake pad-to-caliper clearances. When the direction of travel is
changed, the brake pads may "shift" towards the new direction of travel. When the brake pad
contacts the caliper, a clicking noise may be heard.
To minimize this clicking noise, a disc brake caliper grease has been made available for use during
brake service/maintenance operations. Under normal usage conditions this grease should be
effective for a period of 6 months to 1 year.
Applicable Vehicles ^
1990 - 2000 model year Toyota vehicles, all models.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

Vehicle Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Exhaust System - Sulfur Smell
Fuel: Technical Service Bulletins Exhaust System - Sulfur Smell
ENGINE EG003-03
February 24, 2003
Title: SULFUR ODOR FROM EXHAUST
Models: All Models
Introduction
Some owners of Toyota vehicles may experience a sulfur-like or "rotten egg" odor from the exhaust
system. Sulfur is a natural component of crude oil from which gasoline is refined and the amount of
sulfur can be decreased through the refining process. The amount of sulfur in fuel sold in California
is regulated, however gasoline sold in other states can have substantially higher sulfur content.
Sulfur content also varies considerably between gasoline brands and locations.
Applicable Vehicles
^ All Models.
Repair Procedure
A sulfur odor emitted from the vehicle's tailpipe does not necessarily indicate that there is an issue
with the engine's running condition, but is most likely directly related to the fuel.
^ If the vehicle is exhibiting an excessive sulfur odor, the following checks should be performed:
^ If the MIL light is ON, check for DTCs and repair as necessary.
If no trouble is found after performing the above check, recommend the customer try a different
source of fuel.
Replacement of oxygen sensors, air/fuel ratio sensors or catalytic converters will not reduce the
odor and will therefore not be considered warrantable.

When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil
change, causing fluctuations in the magnetic field and generating an electromotive force in the pick
up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor
generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

System Outline
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is

INSPECTION PROCEDURE
HINT: Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because
freeze frame records the engine conditions when the malfunction is detected, when troubleshooting
it is useful for determining whether the vehicle was running or stopped, the engine warmed up or
not, the air-fuel ratio lean or rich, etc. at the time of the malfunction.

Air Flow Meter/Sensor: Description and Operation
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a
platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow
meter works on the principle that the hot wire and thermistor located in the intake air bypass of the
housing detect any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot
wire. This current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set
temperature.

Shift Solenoid: Description and Operation
DESCRIPTION
Shift Solenoid 1-2
The ECM uses signals from the vehicle speed sensor and crankshaft position sensor to detect the
actual gear position (1st, 2nd, 3rd or O/D gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect
mechanical trouble of the shift solenoid valves, valve body or automatic transaxle (clutch, brake or
gear etc.).
Shifting from 1st to O/D is performed in combination with ON and OFF of the shift solenoid valves
No.1 and No.2 controlled by ECM. If an open or short circuit occurs in either of the shift solenoid
valves, the ECM controls the remaining normal shift solenoid valve to allow the vehicle to be
operated smoothly (Fail safe function).
Fail Safe Function:
If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift
solenoid ON and OFF to shift to the gear positions shown. The ECM also turns the shift solenoid
valve SL OFF at the same time. If both solenoids are malfunctioning, hydraulic control cannot be
performed electronically and must be done manually.
Shift Solenoid Valve SL
The ECM uses the signals from the Throttle position sensor, Air-flow meter and Crankshaft position
sensor to monitor the engagement condition of the lock-up clutch.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

Transmission Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Disk Brake Rotor Surface Rust Removal
The brake rotors are made of cast iron so they may show gradual build-up of surface rust during
long term storage. At least once every two months drive the vehicle and use the brakes normally
stopping from about 30 mph at least 20 times. This regular usage will help prevent severe rust build
up and the possibility of unwanted brake vibration concerns due to rust.
NOTE
^ If the brake vibration still occurs after the braking cycle, determine the root cause of the brake
vibration and repair.
^ Brake rotor resurfacing may be required if the rust was severe and resulted in excessive rotor
thickness variation.

Vehicle Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Then the ECM compares the engagement condition of the lock-up clutch with the lock-up schedule
in the ECM memory to detect mechanical trouble of the shift solenoid valve SL, valve body, torque
converter clutch or automatic transaxle (clutch, brake or gear etc.).
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic
pressure acting on the lock-up relay valve, which then controls operation of the lock-up clutch.
Fail Safe Function: If the ECM detects a malfunction, it turns the shift solenoid valve SL OFF.

System Outline
Current always flows to TERMINAL 12 of the integration relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the Ignition SW is turned ON, current flows from the GAUGE fuse to TERMINAL 6 of the
integration relay. At the same time, current flows to TERMINAL A-2 of the relay from the GAUGE
fuse through the Seat Belt Warning Light. This current activates the integration relay and, for
Approx. 4-8 Seconds, current flowing through the warning light flows from TERMINAL A-2 of relay
to TERMINAL A-7 to GROUND, causing the warning Light to Light up. At the same time as the
warning Light Lights up, a buckle SW ON signal is input to TERMINAL A-3 of the integration relay,
the current flowing from TERMINAL 12 of the relay flows to TERMINAL A-7 to GROUND and the
Seat Belt Warning Buzzer Sounds for Approx. 4-8 Seconds. However, if the Seat Belt is put ON
(Buckle SW OFF) during this period (While The Buzzer Is Sounding), signal input to TERMINAL
A-3 of the integration relay Stops and the current flowing from TERMINAL 12 of the integration
relay to TERMINAL A-7 to GROUND is cut, causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the Ignition Key inserted in the key Cylinder (Unlock warning SW ON), the Ignition SW still
OFF and front LH door open (Door Courtesy SW ON), when a signal is input to TERMINAL A-10 of
the integration relay, the Integration Relay operates, current flows from TERMINAL 6 of the relay to
TERMINAL A-7 to GROUND and the Key Reminder Buzzer Sounds.

Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

d. Disconnect and reconnect the connectors while watching the test light.
The short lies between the connector where the test light stays lit and the connector where the light
goes out.
e. Find the exact location of the short by lightly shaking the problem wire along the body.
CAUTION:
a. Do not open the cover or the case of the ECU unless absolutely necessary. (If the IC terminals
are touched, the IC may be destroyed by
static electricity.)
b. When replacing the internal mechanism (ECU part) of the digital meter, be careful that no part of
your body or clothing comes in contact

Camshaft Position Sensor: Description and Operation
The Camshaft position sensor (G signal) consists of a signal plate and pick up coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust
camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil
change, causing fluctuations in the magnetic field and generating an electromotive force in the pick
up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor
generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft
angle and the engine speed by the NE signals.
Page 1524
Coolant Temperature Sensor/Switch (For Computer): Description and Operation
A thermistor that is built into the engine coolant temperature sensor changes the resistance value
according to the engine coolant temperature.
The lower the engine coolant temperature sensor, the greater the thermistor resistance value, and
the higher the engine coolant temperature sensor temperature, the lower the thermistor resistance
value.
The engine coolant temperature sensor is connected to the ECM. The 5 V power source voltage in
the ECM is applied to the engine coolant temperature sensor from the terminal THA via a resistor
R. That is, the resistor R and the engine coolant temperature sensor are connected in series.
When the resistance value of the engine coolant temperature sensor changes in accordance with
changes in the engine coolant temperature, the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to improve driveability during cold engine
operation.
If the ECM detects the DTC P0115, it operates fail safe function in which the engine coolant
temperature is assumed to be 80°C (176°F).

Shift Indicator: Description and Operation Electronically Controlled Transmission and A/T Indicator
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is no continuous to either No.1 or No.2 solenoid.
2. LOCK-UP OPERATION
When the engine control module judges from each signal that lock-up operation conditions have
been met, current flows from TERMINAL SL of the Engine Control Module to TERMINAL 3 of the
Electronically Controlled Transmission solenoid to GROUND, causing continuity to the lock-up
solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (stop light SW on) when driving in lock-up condition, a signal is
input to TERMINAL BK of the engine control module. The engine control module operates and
continuous to the lock-up solenoid is cut.

HINT: Always use a fully charged battery to obtain engine speed of 250 rpm or more.
d. Repeat steps a. through c. for each cylinder.
NOTICE: This measurement must be done in as short a time as possible.
Compression pressure: 1,230 kPa (12.5 kgf/cm2, 178 psi) or more Minimum pressure: 880 kPa
(9.0 kgf/cm2, 127 psi) Difference between each cylinder: 98 kPa (1.0 kgf/cm2, 14 psi) or less
e. If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into
the cylinder through the spark plug hole and
repeat steps a. through c. for cylinders with low compression. If adding oil helps the compression, chances are that the piston rings and/or cylinder bore are worn

Shift Indicator: Description and Operation Electronically Controlled Transmission and A/T Indicator
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is no continuous to either No.1 or No.2 solenoid.
2. LOCK-UP OPERATION
When the engine control module judges from each signal that lock-up operation conditions have
been met, current flows from TERMINAL SL of the Engine Control Module to TERMINAL 3 of the
Electronically Controlled Transmission solenoid to GROUND, causing continuity to the lock-up
solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (stop light SW on) when driving in lock-up condition, a signal is
input to TERMINAL BK of the engine control module. The engine control module operates and
continuous to the lock-up solenoid is cut.

Shift Indicator: Description and Operation Electronically Controlled Transmission and A/T Indicator
Previous automatic transmissions have selected each gear shift using mechanically controlled
throttle hydraulic pressure, governor hydraulic pressure and lock-up hydraulic pressure. The
Electronically Controlled Transmission, however, electrically controls the governor pressure and
lock-up pressure through the solenoid valve. Control of the solenoid valve by the engine control
module based on the input signals from each sensor makes smooth driving possible by shift
selection for each gear which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate
to the driving conditions, based on input signals from the engine coolant temp. sensor to
TERMINAL THW of the engine control module, and also the input signals to TERMINAL SP2+ of
the engine control module from the Vehicle Speed Sensor devoted to the electronically controlled
transmission. Current is then output to the electronically controlled transmission solenoid. When
shifting to 1st speed, Current flows from TERMINAL S1 of the Engine Control Module to
TERMINAL 1 of the Electronically Controlled Transmission solenoid to GROUND, and continuity to
the No.1 solenoid causes the shift.
For 2nd speed, current flows from TERMINAL S1 of the Engine Control Module to TERMINAL 1 of
the Electronically Controlled Transmission Solenoid to GROUND, and from TERMINAL S2 of the
Engine Control Module to TERMINAL 2 of the Electronically Controlled Transmission solenoid to
GROUND, and continuity to solenoids No.1 and No.2 causes the shift.
For 3rd speed, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into
4th speed (overdrive) takes place when there is no continuous to either No.1 or No.2 solenoid.
2. LOCK-UP OPERATION
When the engine control module judges from each signal that lock-up operation conditions have
been met, current flows from TERMINAL SL of the Engine Control Module to TERMINAL 3 of the
Electronically Controlled Transmission solenoid to GROUND, causing continuity to the lock-up
solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (stop light SW on) when driving in lock-up condition, a signal is
input to TERMINAL BK of the engine control module. The engine control module operates and
continuous to the lock-up solenoid is cut.

TITLE: SRS OCCUPANT CLASSIFICATION SYSTEM INITIALIZATION
SECTION: ELECTRICAL BULLETIN # 177
MODELS: ALL EQUIPPED TOYOTA LEXUS and SCION MODELS
DATE: MARCH 2010
Models equipped with a Supplemental Restraint System (SRS) Occupant Classification System
(OCS) will enable or disable the passenger front and side airbags based on seat occupancy
passenger weight and seat belt latch engagement.
If an equipped vehicle sustains collision damage or if the front passenger seat or any of the OCS
components are serviced the SRS Malfunction Indicator Light (MIL) may illuminate setting a
Diagnostic Trouble Code (DTC).
NOTE:
It is necessary to diagnose and repair the root cause of a SRS or OCS DTC before initializing the
OCS system. If SRS and OCS DTC's are not cleared the system may not operate properly.
Be sure to check and clear DTC's and perform OCS initialization per repair manual instructions
with a Techstream Special Service Tool (SST) or capable diagnostic tester.
Any of the following conditions could set a DTC illuminate the SRS MIL or cause the PASSENGER
AIRBAG light to indicate incorrectly regardless of occupancy:
^ The OCS Electronic Control Unit (ECU) is replaced
^ Accessories such as a seatback tray are installed on the passenger seat
^ The passenger seat is removed and replaced or reinstalled
^ The vehicle is involved in an accident or collision

Ford Made System
Brake Switch (Cruise Control): Description and Operation Ford Made System
CIRCUIT DESCRIPTION
When the brake is on, battery positive voltage normally applies through the STOP fuse and stop
light switch to terminal STP- of the ECU and the ECU turns the cruise control off. A fail-safe
function is provided so that cancel functions normally, even if there is a malfunction in the stop light
signal circuit. If the harness connected to terminal STP- has an open circuit1 terminal STP- will
have battery positive voltage and the cruise control will be turned off. Also, when the brake is on,
the magnetic clutch is cut mechanically by the stop light switch, turning the cruise control off.

1. WARM UP AND STOP ENGINE 2. REMOVE INTAKE AIR CONNECTOR 3. DISCONNECT
HIGH-TENSION CORDS FROM SPARK PLUGS
NOTICE: Pulling on or bending the cords may damage the conductor inside.
4. REMOVE SPARK PLUGS
5. CHECK CYLINDER COMPRESSION PRESSURE
a. Insert a compression gauge into the spark plug hole. b. Fully open the throttle c. While cranking
the engine, measure the compression pressure.
HINT: Always use a fully charged battery to obtain engine speed of 250 rpm or more.
d. Repeat steps a. through c. for each cylinder.
NOTICE: This measurement must be done in as short a time as possible.
Compression pressure: 1,230 kPa (12.5 kgf/cm2, 178 psi) or more Minimum pressure: 880 kPa
(9.0 kgf/cm2, 127 psi) Difference between each cylinder: 98 kPa (1.0 kgf/cm2, 14 psi) or less
e. If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into
the cylinder through the spark plug hole and
repeat steps a. through c. for cylinders with low compression. If adding oil helps the compression, chances are that the piston rings and/or cylinder bore are worn
or damage.
- If pressure stays low, a valve may be sticking or seating is improper, or there may be leakage
past the gasket.

Parking and Paint Protection
^ Storage areas should be paved, well lit and secure. If your off-site storage lot is not paved,
spread gravel down to minimize mud and dust. Be sure vehicles are driven carefully when moving
them to or from a long-term lot. This will help minimize damage to the paint finish from road grit or
gravel.
^ Park vehicles from right to left at least three feet apart. Leave enough space front and rear to
easily walk between rows.
^ HVAC vent controls should be set to "Recirc" to minimize dust and odor intrusion.
^ Make sure the plastic door edge protectors are in place and fold in the side view mirror (if
applicable).
^ Anti-rust covers or anti-rust film should remain on vehicle during storage
1. Anti-Rust Covers (behind wheel) should be removed at PDS.
2. Anti-Rust Film (applied to wheel) should be removed just prior to customer delivery.
^ Wash vehicles frequently.
Battery
^ Turn off all electrical accessories, make sure windows and sunroof are closed and check that the
transmission is in "park" (first or reverse for manual transmission vehicles). Do not apply the
parking brake.
^ Test batteries monthly (more often in high heat or cold areas), using the Digital Battery System
^ Analyzer (P/N 00002-V8150-KIT). Refer to TSB PG001-06, "Battery Maintenance for In Stock
Vehicles and Pre-Delivery" for complete battery maintenance procedures.
^ To reduce battery drain during long-term storage, remove the battery ground (-) cable of each
vehicle and reinstall just before delivery to the customer. Locate the current PDS TSB on TIS for
complete details.
^ If a hybrid vehicle is put into storage, the state of charge (SOC) of it's battery and auxiliary battery
will gradually decrease. To prevent the auxiliary battery from becoming discharged during storage,
proper maintenance is necessary. Refer to TSB "Maintenance for HV & Auxiliary Batteries" for
procedure and additional information.
Tire Inflation Pressure
If the vehicle is parked for long periods without being moved, a flat spot may develop on each tire
surface in contact with the ground, even if the tires are inflated to specification. Tire inflation
pressure should be checked once a month.
Tire inflation pressure for storage only: 45 psi.
Parts Rust
If the vehicles in your storage area are exposed to a sea breeze and/or a significant precipitation
corrosion with rust in some parts may occur.
If rust is found remove it and treat it by applying rust inhibitor to prevent recurrence. Engine Starting
and Vehicle Movement
If the vehicle is stored over an extended period of time starting and running the engine periodically
will ensure smooth running operation.
1. Start and operate the engine at an engine speed under 1,500 RPM for 15 minutes or longer.
This also eliminates moisture in the exhaust system.
NOTE
Be sure to allow sufficient clearance at the rear of the vehicle to prevent other vehicles stored
behind from getting damaged by exhaust gas.
2. Move the vehicle at least 30 feet to lubricate the transmission and differential and prevent tire
flat-spot damage.
3. Raise engine speed above 3,000 RPM 10 times to eliminate moisture from the exhaust.
A/C Compressor Lubrication
To minimize the possibility of damage to the A/C compressor while storing a vehicle perform the
following recommended maintenance procedures at
Page 4738
Battery Replacement
If a vehicle battery needs to be replaced for a warrantable condition, complete a Warranty Battery
Label and affix it to the failed battery for proper warranty parts and claim processing. Include the
Vehicle Identification Number ("IN) and warranty code on the Warranty Battery Label.
Battery Maintenance
Recommended Battery Maintenance:
In addition to this new pre-delivery battery test, a monthly battery inspection is still required for
stored vehicles. If your dealership is located in an area subject to extreme temperatures (hot or
cold), periodic maintenance may need to be performed more frequently.
To reduce parasitic battery drain on vehicles in storage for one week or more, the negative (-)
battery cable should always be disconnected to reduce battery discharge. When the negative (-)
battery cable is reconnected, please check and reset electrical components, such as the clock,
radio, etc., and re-initialize all applicable systems/functions.
Refer to the appropriate model and year service bulletins for specific details. For example:
^ TSB No. PD008-05, "Power System Initialization During PDS" (2005 model year)
^ TSB No. PDO14-06, "Power System Initialization During PDS" (2006 model year)

Brake Signal: Description and Operation
Stop Light Switch Signal
Engine
This signal is used to detect when the brakes have been applied. The STP signal voltage is the
same as the voltage supplied to the stop lights.
The STP signal is used mainly to control the fuel cut-off engine speed (The fuel cut-off engine
speed is reduced slightly when the vehicle is braking.).
Automatic Transaxle
The purpose of this circuit is to prevent the engine from stalling, while driving in lock-up condition,
when brakes are suddenly applied.
When the brake pedal is operated, this switch sends a signal to ECM. Then the ECM cancels
operation of the lock-up clutch while braking is in progress.

Oxygen Sensor: Description and Operation
DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a
three-way catalytic converter is used, but for the most efficient use of the three-way catalytic
converter, the air-fuel ratio must be precisely controlled so that it is always close to the
stoichiometric air-fuel ratio.
The oxygen sensor has the characteristic whereby its output voltage changes suddenly in the
vicinity of the stoichiometric air-fuel ratio. This is used to detect the oxygen concentration in the
exhaust gas and provide feedback to the computer for control of the air-fuel ratio.
When the air-fuel ratio becomes LEAN, the oxygen concentration in the exhaust increases and the
oxygen sensor informs the ECM of the LEAN condition (small electromotive force: <0.45 V).
When the air-fuel ratio is RICHER than the stoichiometric air-fuel ratio the oxygen concentration in
the exhaust gas in reduced and the oxygen sensor informs the ECM of the RICH condition (large
electromotive force: > 0.45 V).
The ECM judges by the electromotive force from the oxygen sensor whether the air-fuel ratio is
RICH or LEAN and controls the injection time accordingly. However, if malfunction of the oxygen
sensor causes output of abnormal electromotive force, the ECM is unable to perform accurate
air-fuel ratio control. The oxygen sensors include a heater which heats the zirconia element. The
heater is controlled by the ECM. When the intake air volume is low (the temp. of the exhaust gas is
low) current flows to the heater to heat the sensor for accurate oxygen concentration detection.

Shift Solenoid: Description and Operation
DESCRIPTION
Shift Solenoid 1-2
The ECM uses signals from the vehicle speed sensor and crankshaft position sensor to detect the
actual gear position (1st, 2nd, 3rd or O/D gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect
mechanical trouble of the shift solenoid valves, valve body or automatic transaxle (clutch, brake or
gear etc.).
Shifting from 1st to O/D is performed in combination with ON and OFF of the shift solenoid valves
No.1 and No.2 controlled by ECM. If an open or short circuit occurs in either of the shift solenoid
valves, the ECM controls the remaining normal shift solenoid valve to allow the vehicle to be
operated smoothly (Fail safe function).
Fail Safe Function:
If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift
solenoid ON and OFF to shift to the gear positions shown. The ECM also turns the shift solenoid
valve SL OFF at the same time. If both solenoids are malfunctioning, hydraulic control cannot be
performed electronically and must be done manually.
Shift Solenoid Valve SL
The ECM uses the signals from the Throttle position sensor, Air-flow meter and Crankshaft position
sensor to monitor the engagement condition of the lock-up clutch.

Coolant Temperature Sensor/Switch (For Computer): Description and Operation
A thermistor that is built into the engine coolant temperature sensor changes the resistance value
according to the engine coolant temperature.
The lower the engine coolant temperature sensor, the greater the thermistor resistance value, and
the higher the engine coolant temperature sensor temperature, the lower the thermistor resistance
value.
The engine coolant temperature sensor is connected to the ECM. The 5 V power source voltage in
the ECM is applied to the engine coolant temperature sensor from the terminal THA via a resistor
R. That is, the resistor R and the engine coolant temperature sensor are connected in series.
When the resistance value of the engine coolant temperature sensor changes in accordance with
changes in the engine coolant temperature, the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to improve driveability during cold engine
operation.
If the ECM detects the DTC P0115, it operates fail safe function in which the engine coolant
temperature is assumed to be 80°C (176°F).

Title O2S TEST RESULTS (MODE 05)
Models All '96 - '03, '04 Corolla, ECHO, Matrix, Sienna & Scion xA & xB
Introduction
This Service Bulletin contains Oxygen Sensor (O2S) Monitor threshold values for all models from
1996 to 2003 and some 2004 models. Starting in 2004, the O2S Monitor threshold values can be
found in the repair manual. These values are used when analyzing the O2S test results to
determine the O2S condition.
Applicable Vehicles ^
All 1996 - 2003 model year Toyota vehicles.
^ 2004 model year Corolla, ECHO, Matrix and Sienna vehicles.
^ 2004 model year Scion xA and xB vehicles.
Function Description
Checking O2S Test Results
To view O2S test results, the O2S Monitor must be completed and the test results must be
checked within the same key cycle. If the ignition key is cycled OFF, the O2S test results will be set
to the minimum or maximum limits, and all test results will be erased. The O2S test results are
stored in the ECU (SAE term: Powertrain Control Module/PCM) when the monitor is completed.
The test results are static and will not change once the monitor is complete.
The process for checking 02S test results is described in the following three basic steps:
1. Completing the O2S Readiness Monitor.
2. Accessing O2S Test Results.
3. Comparing O2S Test Results to Failure Thresholds.
Required SSTs
NOTE:
Additional Diagnostic Tester Kits, Program Cards or other SSTs may be ordered by calling
SPX-OTC at 1-800-933-8335.
Warranty Information
Completing O2S Readiness Monitor
1. Clear any stored Diagnostic Trouble Codes (DTCs) using the Toyota Diagnostic Tester.

Overdrive Indicator Lamp: Description and Operation
O/D Main Switch & O/D Off Indicator Light
The O/D main switch contacts go open when the switch is pushed in and go closed when it is
pushed out. If O/D main switch is at OFF position, the O/D OFF indicator light lights up, and the
ECM prohibits shifting overdrive.
While driving uphill with cruise control activated, in order to minimize gear shifting and provide
smooth cruising overdrive may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels
overdrive shifting until these signals are discontinued.

Power Source
The "Current Flow Chart" images, describes which parts each power source (fuses, fusible links,
and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when
battery power is supplied to each system are explained. Since all System Circuit diagrams start
from the power source, the power source system must be fully understood.

Oxygen Sensor: Description and Operation
DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a
three-way catalytic converter is used, but for the most efficient use of the three-way catalytic
converter, the air-fuel ratio must be precisely controlled so that it is always close to the
stoichiometric air-fuel ratio.
The oxygen sensor has the characteristic whereby its output voltage changes suddenly in the
vicinity of the stoichiometric air-fuel ratio. This is used to detect the oxygen concentration in the
exhaust gas and provide feedback to the computer for control of the air-fuel ratio.
When the air-fuel ratio becomes LEAN, the oxygen concentration in the exhaust increases and the
oxygen sensor informs the ECM of the LEAN condition (small electromotive force: <0.45 V).
When the air-fuel ratio is RICHER than the stoichiometric air-fuel ratio the oxygen concentration in
the exhaust gas in reduced and the oxygen sensor informs the ECM of the RICH condition (large
electromotive force: > 0.45 V).
The ECM judges by the electromotive force from the oxygen sensor whether the air-fuel ratio is
RICH or LEAN and controls the injection time accordingly. However, if malfunction of the oxygen
sensor causes output of abnormal electromotive force, the ECM is unable to perform accurate
air-fuel ratio control. The oxygen sensors include a heater which heats the zirconia element. The
heater is controlled by the ECM. When the intake air volume is low (the temp. of the exhaust gas is
low) current flows to the heater to heat the sensor for accurate oxygen concentration detection.

Service and Repair
Air Bag(s) Arming and Disarming: Service and Repair
CAUTION:
* Work must be started 90 seconds after the ignition switch is turned to the "LOCK" position and
the negative (-) terminal cable is disconnected from
the battery. (The SRS is equipped with a back-up power source so that if work is started within 90
seconds of disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)
* When the negative (-) terminal cable is disconnected from the battery, the memory of the clock
and audio system will be canceled. So before starting
work, make a record of the contents memorized in the audio memory system. When work is
finished, reset the audio systems as before and adjust the clock. To avoid erasing the memory of
each memory system, never use a backup power supply from outside the vehicle.
* Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs. * Do not expose the steering wheel pad, front passenger airbag assembly, airbag sensor
assembly or front airbag sensor directly to hot air or flames.

Air Flow Meter/Sensor: Description and Operation
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a
platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow
meter works on the principle that the hot wire and thermistor located in the intake air bypass of the
housing detect any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot
wire. This current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set
temperature.

INSPECTION PROCEDURE
HINT: Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because
freeze frame records the engine conditions when the malfunction is detected, when troubleshooting
it is useful for determining whether the vehicle was running or stopped, the engine warmed up or
not, the air-fuel ratio lean or rich, etc. at the time of the malfunction.

Transmission Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Camshaft Position Sensor: Description and Operation
The Camshaft position sensor (G signal) consists of a signal plate and pick up coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust
camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil
change, causing fluctuations in the magnetic field and generating an electromotive force in the pick
up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor
generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft
angle and the engine speed by the NE signals.

O/D Main Switch & O/D Off Indicator Light
The O/D main switch contacts go open when the switch is pushed in and go closed when it is
pushed out. If O/D main switch is at OFF position, the O/D OFF indicator light lights up, and the
ECM prohibits shifting overdrive.
While driving uphill with cruise control activated, in order to minimize gear shifting and provide
smooth cruising overdrive may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels
overdrive shifting until these signals are discontinued.

Igniter: Description and Operation
CIRCUIT DESCRIPTION
A DIS (Direct Ignition System) has been adopted, The DIS improves the ignition timing accuracy,
reduces high-voltage loss and enhances the overall reliability of the ignition system by eliminating
the distributor. The DIS is a 2-cylinder simultaneous ignition system which ignites 2 cylinders
simultaneously with 1 ignition coil. In the 2-cylinder simultaneous ignition system, each of the 2
spark plugs is connected to the end of the secondary winding, High voltage generated in the
secondary winding is applied directly to the 2 spark plugs. The sparks of the 2 spark plugs pass
simultaneously from the center electrode to the ground electrode. The ECM determines ignition
timing and outputs the ignition signals (IGT) for each cylinder. Based on IGT signals, the power
transistors in the igniter cuts off the current to the primary coil in the ignition coil is supplied
simultaneously to the two spark plugs via the high-tension cords that are connected to the both
ends of the secondary coil. At the same time, the igniter also sends an ignition confirmation signal
(IGF) as a fail-safe measure to the ECM.

Coolant Temperature Sensor/Switch (For Computer): Description and Operation
A thermistor that is built into the engine coolant temperature sensor changes the resistance value
according to the engine coolant temperature.
The lower the engine coolant temperature sensor, the greater the thermistor resistance value, and
the higher the engine coolant temperature sensor temperature, the lower the thermistor resistance
value.
The engine coolant temperature sensor is connected to the ECM. The 5 V power source voltage in
the ECM is applied to the engine coolant temperature sensor from the terminal THA via a resistor
R. That is, the resistor R and the engine coolant temperature sensor are connected in series.
When the resistance value of the engine coolant temperature sensor changes in accordance with
changes in the engine coolant temperature, the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to improve driveability during cold engine
operation.
If the ECM detects the DTC P0115, it operates fail safe function in which the engine coolant
temperature is assumed to be 80°C (176°F).
Page 722
Transmission Position Switch/Sensor: Description and Operation
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it
goes on terminal NSW of the ECM is grounded to body ground via the starter relay, thus the
terminal NSW voltage becomes 0 V. When the shift lever is in the D, 2, L or R position, the
park/neutral position switch goes off, so the voltage of ECM. Terminal NSW becomes battery
voltage, the voltage of the ECM internal power source. If the shift lever is moved from the N
position to the D position, this signal is used for air-fuel ratio correction and for idle speed control
(estimated control), etc.
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The
ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is
not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in
D position.
When the shift position is except D, a signal is sent from the park/neutral position switch to the
ECU. When this signal is input during cruise control driving, the ECU cancels the cruise control.

Igniter: Description and Operation
CIRCUIT DESCRIPTION
A DIS (Direct Ignition System) has been adopted, The DIS improves the ignition timing accuracy,
reduces high-voltage loss and enhances the overall reliability of the ignition system by eliminating
the distributor. The DIS is a 2-cylinder simultaneous ignition system which ignites 2 cylinders
simultaneously with 1 ignition coil. In the 2-cylinder simultaneous ignition system, each of the 2
spark plugs is connected to the end of the secondary winding, High voltage generated in the
secondary winding is applied directly to the 2 spark plugs. The sparks of the 2 spark plugs pass
simultaneously from the center electrode to the ground electrode. The ECM determines ignition
timing and outputs the ignition signals (IGT) for each cylinder. Based on IGT signals, the power
transistors in the igniter cuts off the current to the primary coil in the ignition coil is supplied
simultaneously to the two spark plugs via the high-tension cords that are connected to the both
ends of the secondary coil. At the same time, the igniter also sends an ignition confirmation signal
(IGF) as a fail-safe measure to the ECM.

Introduction
This Service Bulletin contains Oxygen Sensor (O2S) Monitor threshold values for all models from
1996 to 2003 and some 2004 models. Starting in 2004, the O2S Monitor threshold values can be
found in the repair manual. These values are used when analyzing the O2S test results to
determine the O2S condition.
Applicable Vehicles ^
All 1996 - 2003 model year Toyota vehicles.
^ 2004 model year Corolla, ECHO, Matrix and Sienna vehicles.
^ 2004 model year Scion xA and xB vehicles.
Function Description
Checking O2S Test Results
To view O2S test results, the O2S Monitor must be completed and the test results must be
checked within the same key cycle. If the ignition key is cycled OFF, the O2S test results will be set
to the minimum or maximum limits, and all test results will be erased. The O2S test results are
stored in the ECU (SAE term: Powertrain Control Module/PCM) when the monitor is completed.

Intake Air Temperature Sensor: Description and Operation
The intake air temperature sensor is built into the air cleaner cap and senses the intake air
temperature. A thermistor built in the sensor changes the resistance value according to the intake
air temperature.
Figure 1
The lower the intake air temperature, the greater the thermistor resistance value, and the higher
the intake air temperature, the lower the thermistor resistance value.
The intake air temperature sensor is connected to the ECM. The 5 V power source voltage in the
ECM is applied to the intake air temperature sensor from the terminal THA via a resistor R. That is,
the resistor R and the intake air temp. sensor are connected in series. When the resistance value
of the intake air temp. sensor changes in accordance with changes in the intake air temperature,
the potential at terminal THA also changes. Based on this signal, the ECM increases the fuel
injection volume to improve driveability during cold engine operation.

Key Reminder Switch: Description and Operation
Current always flows to TERMINAL 12 of the integration relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the Ignition SW is turned ON, current flows from the GAUGE fuse to TERMINAL 6 of the
integration relay. At the same time, current flows to TERMINAL A-2 of the relay from the GAUGE
fuse through the Seat Belt Warning Light. This current activates the integration relay and, for
Approx. 4-8 Seconds, current flowing through the warning light flows from TERMINAL A-2 of relay
to TERMINAL A-7 to GROUND, causing the warning Light to Light up. At the same time as the
warning Light Lights up, a buckle SW ON signal is input to TERMINAL A-3 of the integration relay,
the current flowing from TERMINAL 12 of the relay flows to TERMINAL A-7 to GROUND and the
Seat Belt Warning Buzzer Sounds for Approx. 4-8 Seconds. However, if the Seat Belt is put ON
(Buckle SW OFF) during this period (While The Buzzer Is Sounding), signal input to TERMINAL
A-3 of the integration relay Stops and the current flowing from TERMINAL 12 of the integration
relay to TERMINAL A-7 to GROUND is cut, causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the Ignition Key inserted in the key Cylinder (Unlock warning SW ON), the Ignition SW still
OFF and front LH door open (Door Courtesy SW ON), when a signal is input to TERMINAL A-10 of
the integration relay, the Integration Relay operates, current flows from TERMINAL 6 of the relay to
TERMINAL A-7 to GROUND and the Key Reminder Buzzer Sounds.

Oxygen Sensor: Description and Operation
DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a
three-way catalytic converter is used, but for the most efficient use of the three-way catalytic
converter, the air-fuel ratio must be precisely controlled so that it is always close to the
stoichiometric air-fuel ratio.
The oxygen sensor has the characteristic whereby its output voltage changes suddenly in the
vicinity of the stoichiometric air-fuel ratio. This is used to detect the oxygen concentration in the
exhaust gas and provide feedback to the computer for control of the air-fuel ratio.
When the air-fuel ratio becomes LEAN, the oxygen concentration in the exhaust increases and the
oxygen sensor informs the ECM of the LEAN condition (small electromotive force: <0.45 V).
When the air-fuel ratio is RICHER than the stoichiometric air-fuel ratio the oxygen concentration in
the exhaust gas in reduced and the oxygen sensor informs the ECM of the RICH condition (large
electromotive force: > 0.45 V).
The ECM judges by the electromotive force from the oxygen sensor whether the air-fuel ratio is
RICH or LEAN and controls the injection time accordingly. However, if malfunction of the oxygen
sensor causes output of abnormal electromotive force, the ECM is unable to perform accurate
air-fuel ratio control. The oxygen sensors include a heater which heats the zirconia element. The
heater is controlled by the ECM. When the intake air volume is low (the temp. of the exhaust gas is
low) current flows to the heater to heat the sensor for accurate oxygen concentration detection.

Introduction
This Service Bulletin contains Oxygen Sensor (O2S) Monitor threshold values for all models from
1996 to 2003 and some 2004 models. Starting in 2004, the O2S Monitor threshold values can be
found in the repair manual. These values are used when analyzing the O2S test results to
determine the O2S condition.
Applicable Vehicles ^
All 1996 - 2003 model year Toyota vehicles.
^ 2004 model year Corolla, ECHO, Matrix and Sienna vehicles.
^ 2004 model year Scion xA and xB vehicles.
Function Description
Checking O2S Test Results
To view O2S test results, the O2S Monitor must be completed and the test results must be
checked within the same key cycle. If the ignition key is cycled OFF, the O2S test results will be set
to the minimum or maximum limits, and all test results will be erased. The O2S test results are
stored in the ECU (SAE term: Powertrain Control Module/PCM) when the monitor is completed.
The test results are static and will not change once the monitor is complete.
The process for checking 02S test results is described in the following three basic steps:
1. Completing the O2S Readiness Monitor.
2. Accessing O2S Test Results.
3. Comparing O2S Test Results to Failure Thresholds.
Required SSTs
NOTE:
Additional Diagnostic Tester Kits, Program Cards or other SSTs may be ordered by calling
SPX-OTC at 1-800-933-8335.

Transmission Speed Sensor: Description and Operation
The No.1 vehicle speed sensor outputs a 4-pulse signal for every revolution of the rotor shaft,
which is rotated by the transmission output shaft via the driven gear.
After this signal is converted into a more precise rectangular waveform by the waveform shaping
circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the
vehicle speed based on the frequency of these pulse signals.
The No.2 vehicle speed sensor detects the rotation speed of the transmission output shaft and
sends signals to the ECM. The ECM determines the vehicle speed based on these signals.
An AC voltage is generated in the No.2 vehicle speed sensor coil as the rotor mounted on the
output shaft rotates, and this voltage is sent to the ECM.
The gear shift point and lock-up timing are controlled by the ECM based on the signals from this
vehicle speed sensor and the throttle position sensor signal.
If the No.2 vehicle speed sensor malfunctions, the ECM uses input signals from the No.1 vehicle
speed sensor as a back-up signal.

Stop Light Switch Circuit
CIRCUIT DESCRIPTION
When the brake is on, battery positive voltage normally applies through the STOP fuse and stop
light switch to terminal STP- of the ECU and the ECU turns the cruise control off. A fail-safe
function is provided so that cancel functions normally, even if there is a malfunction in the stop light
signal circuit. If the harness connected to terminal STP- has an open circuit1 terminal STP- will
have battery positive voltage and the cruise control will be turned off. Also, when the brake is on,
the magnetic clutch is cut mechanically by the stop light switch, turning the cruise control off.

Continuity and Resistance Check
Continuity And Resistance Check
a. Disconnect the battery terminal or wire so there is no voltage between the check points. b.
Contact the two leads of an ohmmeter to each of the check points.
Continuity And Resistance Check
If the circuit has diodes, reverse the two leads and check again. When contacting the negative lead
to the diode positive side and the positive lead to the negative side, there should be continuity.
When contacting the two leads in reverse, there should be no continuity.
Continuity And Resistance Check
c. Use a volt/ohmmeter with high impedance (10 K Ohms/Volt minimum) for troubleshooting of the
electrical circuit.
