Electronic Engine Controls - V8 S/C 5.0L Petrol (G2255267): Overview

The Engine Management System (EMS) operates the engine to generate the output demanded by the Accelerator Pedal Position (APP) sensor and loads imposed by other systems.

The EMS has a Powertrain Control Module (PCM) that 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 EMS controls the following:

• Charge air
• Fueling
• Ignition timing
• Valve timing
• Cylinder knock
• Idle speed
• Engine cooling fan
• Exhaust emissions
• Evaporative emissions
• Immobilization system interface
• Speed control.
