Engine Ignition

ENGINE IGNITION

This vehicle uses a coil-on-plug electronic ignition system. The coil-on-plug ignition system consists of the following components:
- PCM
- Crankshaft position (CKP) sensor
- Ignition coil-on-plug
- Spark plugs

The PCM and the CKP sensor are also part of the electronic engine controls system. Refer to Computers and Control Systems.

Eight separate ignition coils:
- are controlled by the PCM for the correct firing sequence.
- are mounted directly above each spark plug.

The spark plugs:
- change the high voltage pulse into a spark which ignites the fuel and air mixture
- originally equipped on the vehicle have a nickel alloy electrode for long life.
