Park/neutral Position, Overdrive Control or
Throttle (Accelerator) Position Switches
DESCRIPTION
IPark/neutral position switch
Detects the selector lever position and sends a signal to the
TCM.
I Overdrive control switch
Detects the overdrive control switch position (ON or OFF) and
sends a signal to the TCM.
I Throttle (accelerator) position switch
Consists of a wide open throttle position switch and a closed
throttle (accelerator) position switch.
The wide open throttle position switch sends a signal to the
TCM 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 TCM when the throttle valve is fully closed.

DIAGNOSTIC PROCEDURE
CHECK PARK/NEUTRAL POSITION
SWITCH CIRCUIT.
1. Turn ignition switch to ªONº posi-tion.
(Do not start engine.)
2. Select ªECU INPUT SIGNALSº in Data Monitor.
3. Read out ªR, N, D, 2 and 1 posi- tion switchesº moving selector
lever to each position.
Check the signal of the selector
lever position is indicated properly.

1. Turn ignition switch to ªONº posi-
tion. (Do not start engine.)
2. Check voltage between TCM ter- minals q

2. Select ªECU INPUT SIGNALSº in Data Monitor.
3. Read out ªOVERDRIVE SWITCHº. Check the signal of the overdrive
control switch is indicated prop-
erly.
(Overdrive control switch ªONº
displayed on CONSULT-II means
overdrive ªOFFº.)

drive control switch is ªONº and
ªOFFº.
