Kia Rio: Description - Accelerator Position Sensor (APS) - Engine Control System - Engine Control / Fuel System - Kia Rio UB 2012-2026 Service ManualKia Rio: 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.
