Throttle Position Sensor

WARNING: This page is about a different car, the 1997 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: TP sensor is not adjustable. For further testing procedures, refer to the TESTS W/CODES article or the SYSTEM/COMPONENT TESTS article.

NOTE: Throttle control is electronic with NO mechanical link from engine to accelerator pedal. The PCM and Throttle Actuator Control (TAC) module monitors the position of accelerator pedal based on signals from a nonadjustable Accelerator Pedal Position (APP) sensor. The APP is mounted above the accelerator pedal.
