Electronic Engine Controls - Overview (G1772580): Overview
WARNING: This page is about a different car, the 2013 Jaguar XJ, 2012 Jaguar XJ, 2011 Jaguar XJ, and 2010 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.
The EEC (electronic engine control) system operates the engine to generate the output demanded by the accelerator pedal and loads imposed by other systems. The EEC system has an ECM (engine control module) 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 EEC system controls the following:
- Charge air
- Fueling
- Ignition timing
- Valve timing
- Cylinder knock
- Idle speed
- Engine cooling fan
- Evaporative emissions
- On-board diagnostics
- Immobilization system interface
- Speed control.
