lDo not adjust the adjusting screw (painted white) of the accelerator work unit. (YD22DDTi)
lWhen the harness connector of the accelerator sensor is disconnected, perform²Accelerator
Pedal Released Position Learning².Referto²Basic Service Procedure²in EC section.
INSTALLATION
Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
lCheck that the accelerator pedal moves smoothly within the whole operation range.
lCheck that the accelerator pedal securely returns to the original position.
lFor the electrical inspection of the accelerator pedal assembly, refer toEC-154, "DTC P0121 APP SEN-
SOR"(WITH EURO-OBD) andEC-484, "DTC P0121 APP SENSOR"(WITHOUT EURO-OBD).
(QR20DE)
lFor the electrical inspection of the accelerator work unit, refer toEC-715, "DTC P0120 ACCELERATOR
PEDAL POSITION SENSOR"andEC-783, "DTC P1510 ACCELERATOR PEDAL RELEASED POSI-
TION SWITCH".(YD22DDTi)
lCheck that the drum of the accelerator work unit can be fully opened. (YD22DDTi)

ThefunctionoftheTCMisto:
lReceive input signals sent from various switches and sensors.
lDetermine required line pressure, shifting point, lock-up operation, and engine brake operation.
lSend required output signals to the respective solenoids.
INPUT/OUTPUT SIGNAL OF TCM
SCIA0690E
Sensors, switches and solenoid
valvesFunction
InputPNP switch Detects select lever position and sends a signal to TCM.
Throttle position sensor (accelerator
pedal position(app) sensorDetects throttle valve position and sends a signal to TCM.
Engine speed signal From ECM.
A/T fluid temperature sensor Detects transmission fluid temperature and sends a signal to TCM.
Revolution sensor Detects output shaft rpm and sends a signal to TCM.
Vehicle speed sensorUsed as an auxiliary vehicle speed sensor. Sends a signal when revolution
sensor (installed on transmission) malfunctions.
Overdrive control switch*1Sends a signal, which prohibits a shift to “D
4” (overdrive) position, to the
TCM.
Stop lamp switch Releases lock-up system when depressing pedal in lock-up condition.
