Engine Ignition
WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The electronic ignition system is a coil-on-plug ignition system. The coil-on-plug ignition system consists of the following components:
- Crankshaft position (CKP) sensor
- Ignition coils
- Spark plugs
The CKP sensor:
- Is a variable reluctance sensor.
- Is triggered by a 36-minus-l tooth sensor ring mounted on the crankshaft.
- Provides base timing and crankshaft speed (RPM) to the powertrain control module (PCM).
The 8 separate ignition coils:
- Change low voltage signals from the PCM to high voltage pulses.
- Produce the high voltage pulses to the spark plugs.
- Are connected directly to each spark plug.
The spark plugs:
- Change high voltage pulses into a spark which ignites the fuel and air mixture.
- Originally equipped on the vehicle have a platinum-enhanced active electrode for long life.
