Engine Ignition: Notes
WARNING: This page is about a different car, the 2013 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.
The Electronic Ignition (EI) system consists of the:
- ignition coil
- spark plug wires
- spark plugs
The ignition coil is controlled by the PCM and fires 2 spark plugs simultaneously.
The spark plug wires carry high voltage pulses from the ignition coil to the spark plugs.
The spark plug ignites the fuel and air mixture.
