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.
