Powertrain Control Module (PCM)

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.
