Electronic Engine Controls: Overview
WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The V6 3.0L S/C Petrol engine has an Engine Management System (EMS) controlled by the Powertrain Control Module (PCM).
The EMS operates the engine to generate the output demanded by the Accelerator Pedal Position (APP) sensor and loads imposed by other systems.
The PCM uses a torque-based strategy to evaluate inputs from sensors and other systems, and then produces outputs to engine actuators to produce the required torque.
The PCM controls the following:
- Charge air
- Fueling
- Ignition timing
- Valve timing
- Cylinder knock
- Idle speed
- Engine cooling fan
- Evaporative emissions
- On-Board Diagnostic (OBD)
- Immobilization system interface
- Speed control.
