DIAGNOSTIC CHART

PARTS DESCRIPTION




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




Overdrive switch
Detects the overdrive 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 closed throttle position switch sends a signal to the A/T control unit when the throttle valve is fully closed.
