Accelerator Pedal Position Sensor

The accelerator pedal position sensor is installed on the upper section of the accelerator pedal assembly and detects the depressing amount of the accelerator pedal.

These sensors compose 2 systems. These use potentiometers to convert the amount of accelerator pedal depression to voltage signals and input the signals into HPCM.

HPCM judges the amount and speed of accelerator pedal depression from these signals, and controls the output of the engine and traction motor.
