| Function of the Electronic Throttle System |
| The position of the accelerator pedal is signalled by the engine control unit via two accelerator pedal position senders (variable resistors; located in a housing), which are connected to the accelerator pedal. |
| The throttle valve is activated by an electric motor (throttle valve positioner) in the throttle valve control unit, over the full speed and load range. |
| The electronic throttle system does not only consist of one or two components. The Electronic Throttle is a system that includes all the components, which contribute to determining, controlling and monitoring the position of the throttle valve (e.g. the accelerator pedal position sender, the throttle valve control unit, the EPC warning lamp, the engine control unit,...). |
