Throttle Position Sensor: Description and Operation
Throttle Position (TP) Sensor
THROTTLE POSITION (TP) SENSOR
Typical TP Sensor
The TP sensor is a rotary potentiometer sensor that provides a signal to the PCM that is linearly proportional to the throttle plate/shaft position. The
sensor housing has a 3-blade electrical connector that may be gold plated. The gold plating increases corrosion resistance on terminals and increases
connector durability. The TP sensor is mounted on the throttle body. As the TP sensor is rotated by the throttle shaft, 4 operating conditions are
determined by the PCM from the TP. Those conditions are closed throttle (includes idle or deceleration), part throttle (includes cruise or moderate
acceleration), wide open throttle (includes maximum acceleration or de-choke on crank), and throttle angle rate.
