Accelerator Position Sensor (APS), installed on the
accelerator pedal module, detects the rotation angle of the accelerator
pedal. The APS, one of the most important sensors in engine control
system, consists of two sensors each equipped with individual sensor
power and ground lines. 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.
