Accelerator Pedal Position Sensor
WARNING: This page is about a different car, the 2013 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
The accelerator pedal sensor is integrated with the accelerator pedal. This sensor is a potentiometer that detects the acceleration pedal stroke, converts it to a voltage signal, and transmits the signal to VCM. The sensor transmits its signals through dual lines, providing a minimum driving function even if either line malfunctions. Upon a POWER ON cycle, VCM learns the fully closed position of the acceleration pedal from the accelerator pedal position sensor signal.
