Monitor Description

The accelerator pedal position sensor is mounted on the accelerator pedal bracket. The accelerator pedal position sensor is mounted on the accelerator pedal and has the 2 signal outputs (elements) that are used for engine control and detecting malfunctions in the sensor. When the difference between the voltage output of VPA and VPA2 deviate from the standard, the ECM concludes that the accelerator pedal position sensor is malfunctioning. The ECM turns on the MIL and a DTC is set.
