TORQUE SPECIFICATIONS
The electronic ignition (EI) system is a coil-on-plug ignition system. The coil-on-plug ignition system consists of the
- coil-on-plug.
- spark plugs.
- crankshaft position (CKP) sensor.
- camshaft position (CMP) sensor.
The coil-on-plugs
- change low voltage signals from the powertrain control module (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.
The CKP sensor
- is a variable reluctance sensor.
- is triggered by a 36-minus-1 tooth trigger wheel mounted on the crankshaft.
- provides base timing and crankshaft speed (rpm) to the PCM.
The CMP sensor
- is a Hall-effect sensor.
- provides camshaft rotational location information to the PCM.
Refer to the Introduction - Gasoline Engines .
