Engine Ignition




Engine Ignition

This vehicle uses a coil-on-plug electronic ignition system. The coil-on-plug ignition system consists of the:

- 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 Information.

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.
