Accelerator Pedal Position (APP) Sensor The ability to smoothly accelerate down the road while using an adequate amount of energy is attributed to the accelerator pedal position (APP) sensor. The APP sensor, which is fixed to the throttle body of the 'electronic throttle control system with intelligence' (ETCSi), monitors the position of the throttle pedal. The AAP sensor is also involved in converting the movement of the accelerator pedal into an electronic signal, which then initiates the opening or closing of the throttle body. The accelerator position information is transferred to the throttle actuator control (TAC) module and the powertrain control module (PCM). The accelerator position sensor is made up of two individual sensors, with both sensors designed to have individual sensor return wiring. Each sensor has a varying voltage range. The PCM system receives and processes the electrical signals from the ACC sensors, along with signals from the direct curr...
