Engine Ignition

The electronic ignition (El) system for the 2.0L and 2.3L engines consists of the following components:

• Coil on plug
• Spark plugs
• Crankshaft position (CKP) sensor
• Camshaft position (CMP) sensor

The crankshaft position (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 powertrain control module (PCM).

Refer to ELECTRONIC ENGINE CONTROLS \ , for removal and installation of the CKP sensor.

The coil on plug:

• Is controlled by the PCM.
• Fires two spark plugs simultaneously.

The spark plug:

• Ignites the fuel and air mixture.
