Engine Ignition

Engine Ignition

The Electronic Ignition (EI) system for the 2.3L engine contains the:

- ignition coil.
- spark plugs.
- spark plug wires.
- Crankshaft Position (CKP) sensor.

The CKP sensor:

- is a variable reluctance sensor.
- is mounted on the engine front cover.
- is triggered by a 36-minus-1 tooth trigger wheel located on the crankshaft pulley and damper.
- provides ignition timing and crankshaft speed (rpm) to the PCM.

Refer to Electronic Engine Controls Service and Repair for removal and installation of the CKP sensor.

The ignition coil:

- is controlled by the PCM.
- fires 2 spark plugs simultaneously.

The spark plug:

- ignites the fuel and air mixture.

The spark plug wire:

- carries high voltage pulses from the ignition coil to the spark plugs.
