Accelerator Pedal Position (App) Sensor

Accelerator Pedal Position (APP) sensor, located at top of accelerator pedal, monitors position of accelerator pedal and transmits this information to the Engine Control Module (ECM). The ECM processes this signal with information from other systems to calculate proper control signal for throttle motor contained in Throttle Position (TP) sensor. A closed loop circuit assures precise adjustment of throttle angle based on signals transmitted to ECM from a potentiometer within the TP sensor confirming position of throttle motor. Constant system monitoring by the ECM assures maintenance of set speed.
