Electronic Ignition (EI) System
WARNING: This page is about a different car, the 2010 Ford Pickup, 2010 Ford F550 Super Duty, 2010 Ford F450 Super Duty, and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The 5.4L 3V Electronic Ignition (EI) system consists of:
- eight ignition coils.
- eight spark plugs.
- Crankshaft Position (CKP) sensor.
The 6.8L 3V EI system consists of the:
- ten ignition coils.
- ten spark plugs.
- CKP sensor.
The EI system is a coil-on-plug ignition system which uses one ignition coil for each cylinder attached to the spark plug. The PCM receives a signal from the CKP sensor and sends low voltage signals to each of the ignition coils. The ignition coils turn low voltage signals into high voltage pulses which are passed through the spark plugs to ignite the compressed fuel and air mixture.
