THROTTLE POSITION SENSOR
Typical Throttle Position (TP) Sensor
The Throttle Position (TP) sensor (Figure 42) 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 three-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, four 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.
