INSPECTION

Function And Operation Principle

FUNCTION AND OPERATION PRINCIPLE

Accelerator Position Sensor (APS) is installed on the accelerator pedal module and detects the rotation angle of the accelerator pedal. The APS is one of
the most important sensors in engine control system so it consists of the two sensors which adapt individual sensor power and ground line. The second
sensor monitors the first sensor and its output voltage is half of the first one. If the ratio of the sensor 1 and 2 is out of the range (approximately 1/2), the
diagnostic system judges that it is abnormal.
