Throttle Position (TP)  

Sensor Data

The Throttle Position (TP) sensor is a rotary potentiometer with a resistive element that varies linearly and in direct proportion to the throttle plate angle. The PCM applies a reference voltage (5V) and ground to the sensor and monitors the return voltage to determine throttle plate position. Not only the change but the rate of change can be detected.

 

 

Probable readings for error checking are shown below. Readings can also be obtained by the OBD lead and Vehicle Explorer software with the advantage that this can be done while the vehicle is being driven!
