INSPECTION
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.
