DTC 1101

DESCRIPTION




INHIBITOR SWITCH
Detects the selector lever position and sends a signal to the A/T control unit.




OVERDRIVE CONTROL SWITCH
Detects the overdrive control switch position (ON or OFF) and sends a signal to the A/T control unit.




THROTTLE POSITION SWITCH
Consists of a wide-open throttle position switch and a closed throttle position switch.
The wide-open position switch sends a signal to the A/T control unit when the throttle valve is open at least 1/2 of the full throttle position. The closed throttle position switch sends a signal to the A/T control unit when the throttle valve is fully closed.
