TORQUE SPECIFICATIONS
The electronic ignition (EI) system is a coil-on-plug ignition system. The coil-on-plug ignition system consists of the
- Camshaft position (CMP) sensor.
- Crankshaft position (CKP) sensor.
- Ignition coil-on-plug.
- 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 coil-on-plugs
- 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.
