TORQUE SPECIFICATIONS
The electronic ignition system is a coil-on-plug ignition system. The coil-on-plug ignition system consists of the following components
- Camshaft position (CMP) sensor
- Crankshaft position (CKP) sensor
- Ignition coils
- Spark plugs
The CMP sensor
- is a variable reluctance sensor.
- is mounted in the front cover.
- is triggered by the high point mark on the LH exhaust camshaft.
- provides camshaft rotational location information to the powertrain control module (PCM).
The CKP sensor
- is a variable reluctance sensor.
- is triggered by a 36-minus-l tooth trigger wheel mounted on the crankshaft.
- provides base timing and crankshaft speed (rpm) to the PCM.
The 6 separate ignition coils
- change low voltage signals from the PCM to high voltage pulses.
- 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 a platinum-enhanced active electrode for long life.
