Engine Ignition

ENGINE IGNITION

The electronic ignition (EI) 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).

The coil on plug:
- is controlled by the PCM.
- fires 2 spark plugs simultaneously.

The spark plug:
- ignites the fuel and air mixture.
