Torque Specifications
The electronic ignition (EI) system for the 3.0L engine consists of the following components
- Ignition coil
- Spark plugs
- Spark plug wires
- Crankshaft position (CKP) 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 base 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 two 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 - CNG, FLEX-FUEL & GASOLINE article for additional information on ignition coil matched pairs.
Refer to the INTRODUCTION - CNG, FLEX-FUEL & GASOLINE article for diagnosis and testing of the electronic ignition (EI) system.
Scheme 1
Scheme 2
- Disconnect the spark plug wires by twisting while pulling upward.
- Disconnect the electrical connector from the ignition coil.
- Remove the ignition coil. Remove the bolts. Wipe the ignition coil towers with a clean cloth dampened with soap and water.
- To install, reverse the removal procedure.
