Engine Ignition

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

• Powertrain control module (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 ELECTRONIC ENGINE CONTROLS article.

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.
