Function of EPC system
The position of the accelerator pedal is transmitted to the engine control module via two accelerator pedal position sensors (adjustable resistances,
accommodated in one housing), that are connected to the accelerator pedal.
The position of the accelerator pedal (driver controlled) is a main input for the engine control module.
Operation of the throttle valve occurs via an electric motor (throttle valve actuator) in the throttle valve control module. This is true across the entire
engine speed and engine load spectrum.
