Throttle Position (TP) Sensor
WARNING: This page is about a different variant/trim than selected.
The throttle position sensor (TP sensor) (9B989) is a rotary potentiometer in which the PCM determines four operating modes from the TP signal. These are:
- Closed throttle (idle or deceleration).
- Part throttle (cruise, moderate acceleration).
- Wide open throttle (WOT) (maximum acceleration, de-choke on crank and A/C cutout).
- Throttle angle rate.
