Accelerator pedal (AP) position sensor

Accelerator pedal (AP) position sensor
The accelerator pedal position sensor is mounted together with the accelerator pedal. The sensor transmits a pulse width modulated signal that is proportional to how much the pedal is depressed. The sensor is directly connected to the central electronic module (CEM), which forwards the sensor value out onto the CAN network. The central electronic module (CEM) only uses the signal to be able to generate a diagnostic trouble code should any sensor output signals fall outside of specified values.
