GENERAL SPECIFICATIONS
The electronic ignition (EI) system for the 2.3L engine consists of the following components
- Ignition coil
- Spark plugs
- Spark plug wires
- Crankshaft position (CKP) sensor
- Camshaft position (CMP) 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 powertrain control module (PCM).
Refer to ELECTRONIC ENGINE CONTROLS 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.
Refer to the INTRODUCTION - GASOLINE ENGINES for diagnosis and testing of the ignition system.
