Powertrain Control Module (PCM)
WARNING: This page is about a different car, the 2003 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
The PCM controls the Zetec-E engine. To enable it to do this, the PCM requires comprehensive information regarding the current operating state of the engine. The PCM obtains this information by means of numerous sensors.
- The PCM controls:
- the fully electronic (EI) ignition system
- the sequential electronic fuel injection (SEFI)
- the air-conditioning system in conjunction with the cooling system.
