ENGINE IGNITION SYSTEM -2.3L TORQUE SPECIFICATIONS
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).
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.
Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE for diagnosis and testing of the ignition system.
