Accelerator Position Sensor (APS)

Function And Operation Principle
The Accelerator Pedal Position Sensor (APS) is installed on the accelerator pedal assembly and consists of the two
potentiometers which have independent circuit (power, signal output, and ground) individually. This
system makes the ECM recognize the driver's intention even if one sensor is broken. Also the ECM can diagnose
the sensor by comparing the two sensor's signal..
