Kia Carens: Engine Control System / Accelerator Position Sensor (APS) Description and operation
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.
