3rd Judgement Flicker

DESCRIPTION
Throttle Position Sensor
The throttle position sensor detects the throttle valve position and sends a signal to the 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.
