The Accelerator Pedal Position Sensor is mounted on the accelerator pedal bracket. The accelerator pedal position sensor has two sensor elements/signal outputs: VPA and VPA2. VPA is used to detect the actual accelerator pedal angle (used for engine control) and VPA2 is used to detect malfunctions in VPA. When the difference between the voltage outputs of VPA and VPA2 deviate from the standard, the Engine Control Module (ECM) concludes the accelerator pedal position sensor has a malfunction.
