Throttle Position (TP) Sensor
WARNING: This page is about a different variant/trim than selected.
The TP sensor is a rotary potentiometer sensor that provides a signal to the PCM that is linearly proportional to the throttle plate position. The sensor housing has a 3 blade electrical connector that may be gold plated. The gold plating increases the corrosion resistance on the terminals and increases the connector durability. The TP sensor is mounted on the throttle body. As the TP sensor is rotated by the throttle shaft, the following operating conditions are determined by the PCM:
- closed throttle (includes idle or deceleration)
- part throttle (includes cruise or moderate acceleration)
- wide open throttle (includes maximum acceleration or de-choke on crank)
- throttle angle rate
