Kia Cadenza YG: Engine Control System / Accelerator Position Sensor (APS) Description and Operation

Kia Cadenza YG 2016-2021 Service Manual / Engine Control / Fuel System / Engine Control System / 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.

    Inspection 1. Turn the ignition switch OFF. 2. Disconnect the OTS connector. 3. Remove the OTS. (Refer to "Removal") 4. After immersing the thermistor of the sensor into engine coolant, measure resistance between the OTS terminals 1 and 2.
