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.
