Description





- Throttle position sensor
The throttle position sensor detects the throttle valve position and sends a signal to the Transmission Control Module (TCM).
- Throttle position switch
Consists of a wide open throttle position switch and a closed throttle 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.
