Signal Functions

The APP sensor provides 3 independent input signals to the powertrain control module (PCM) indicating the driver's demand for power and is based upon the rotation angle of the pedal. The PCM determines the APP position by processing and uses the input signals to calculate the desired fuel quantity, injection timing, and the correct injection control pressure.
