Accelerator Pedal Position Sensor: Description and Operation
The accelerator pedal position sensor (1) is located inside the accelerator pedal. The accelerator pedal position sensor (1) can not be serviced by itself.
The accelerator pedal must be replaced as a unit.
The PCM recognizes how the accelerator pedal is being pressed and switches between a few characteristic curves. Eighty percent of the engine's power
is achieved for a pedal travel of about 50% for an aggressive driver and about
40% for a conservative driver. There is no further difference felt above a pedal travel of about 90%.
The characteristic curve for a conservative driver is active after a long drive. Then the accelerator pedal must be pressed down unusually hard to obtain a
higher acceleration level.
The accelerator pedal position sensor in the accelerator pedal determines the opening angle of the throttle valve in the throttle body. The data transfers
over the CAN data bus.
Further functions are: Idle speed control, cruise control, engine torque for ESP operation and short performance limitation; for example, for a higher
