Engine Ignition

Engine Ignition

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 (Crankshaft Position) 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.
