TORQUE SPECIFICATIONS CHART
The electronic ignition system is a coil-on-plug ignition system. The coil-on-plug ignition system consists of the following components
- Crankshaft Position (CKP) sensor
- Ignition coils
- Spark plugs
The CKP sensor
- is a variable reluctance sensor.
- is triggered by a 36-minus-1 tooth sensor ring mounted on the crankshaft.
- provides base timing and crankshaft speed (rpm) to the PCM.
The 8 separate ignition coils
- change low voltage to high voltage pulses based on signals from the PCM.
- produce the high voltage pulses to the spark plugs.
- are connected directly to each spark plug.
The spark plugs
- change high voltage pulses into a spark which ignites the fuel and air mixture.
- originally equipped on the vehicle have an iridium-enhanced active electrode for long life.
