Throttle Position (TP) Sensor

TP sensor is a rotary potentiometer that monitors throttle plate opening. Its signal to the PCM is proportional to throttle plate opening angle and rate of angle change. The TP sensor signal affects air/fuel ratio, injector timing, idle speed, EGR flow and ignition timing. The TP sensor is mounted on throttle body.
