Engine Ignition

The electronic Ignition (EI) system for the 2.3L engine 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 two spark plugs simultaneously.

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