       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.
