Kia Optima: Accelerator Position Sensor (APS). Description and Operation
Description
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.
