Circuit / System Description
The accelerator pedal assembly contains two accelerator pedal position (APP) sensors. The APP sensors are mounted in the pedal assembly and are not serviceable. The APP sensors provide a signal voltage that changes relative to the position of the accelerator pedal. The engine control module (ECM) supplies a separate 5-volt reference and low reference circuit for each of the APP sensors.
The APP sensor 1 signal voltage increases as the pedal is depressed, from approximately 1?volt at rest to above 4?volts when fully depressed. The APP sensor 2 signal voltage increases as the pedal is depressed, from approximately 0.5?volts at rest to more than 2?volts with the accelerator pedal fully depressed.
