Electronic Engine Controls (V8 S/c 5.0L Petrol): Overview Jaguar XF I

OVERVIEW

The electronic engine control (EEC) system operates the engine to generate the output demanded by the accelerator pedal and loads imposed by other systems. The electronic engine control (EEC) system has an engine control module (ECM) that uses a torque-based strategy to evaluate inputs from sensors and other systems, then produces outputs to engine actuators to produce the required torque.

The electronic engine control (EEC) system controls the following

1. Charge air
2. Fueling
3. Ignition timing
4. Valve timing
5. Cylinder knock
6. Noise feedback system
7. Idle speed
8. Engine cooling fan
9. Evaporative emissions
10. On-board diagnostics
11. Immobilization system interface
12. Speed control.
