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:
- 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.

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

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 platinum-enhanced active electrode for long life.
