Self Study Program 210 – Electronic Power Control

With the Electronic Power Control system, the throttle valve is actuated only by an electric motor. This eliminates the need for a Bowden cable between the accelerator pedal and the throttle valve.

It means that the driver input is relayed to the engine control unit via the accelerator  pedal. The engine control unit then sends a corresponding command to the throttle valve positioner.

By positioning the throttle valve, the engine control unit can regulate engine torque even if the driver has not depressed the accelerator pedal.

The result is better co-ordination between and within the engine management systems.

We will now demonstrate that the Electronic Power Control is more than just a substitute for the Bowden accelerator cable.
