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.
