Description and operation
Description

Installed on the accelerator pedal module, the Accelerator Position Sensor (APS) detects the rotation angle of the accelerator pedal. As the APS is one of the most important sensors in the engine control system, each of its two sensors has independent power and ground line. APS 2 monitors APS 1, and its output voltage is half that of APS 1. If the ratio of APS 1 and APS 2 is out of range (approximately 1/2), the diagnostic system judges it as abnormal.
