Under certain engine load conditions there is
also a significant reduction in harmful emissions
and noticeably improved fuel consumption.
The Engine Control Module (ECM) can provide
the optimum combination of throttle valve
opening and charge pressure in order to create
the required torque.
The electronic throttle is not simply a
combination of two or three components, but
rather a complete system comprising all the
elements that together determine the position of
the throttle valve and also control and monitor it.
For example, the Accelerator Pedal Position
Sensor, Throttle Valve Control Module, EPC
warning lamp, Engine Control Module (ECM)
etc.
