TORQUE SPECIFICATIONS
The electronic ignition (El) system for the 3.0L Duratec engine consists of the following components
- Crankshaft position (CKP) sensor
- Camshaft position (CMP) sensor
- 6 ignition coil-on-plugs
- 6 spark plugs
The CKP sensor
- is a variable reluctance sensor.
- is mounted in the front cover.
- is triggered by a 36-minus-l tooth trigger wheel located behind the front cover.
- provides base timing and crankshaft speed (rpm) to the powertrain control module (PCM). For additional information, refer to «ELECTRONIC ENGINE CONTROLS»(ref-233038) .
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 PCM. For additional information, refer to «ELECTRONIC ENGINE CONTROLS»(ref-233038) .
The 6 ignition coil-on-plugs
- are connected directly to each spark plug.
- change low voltage signals from the PCM to high voltage pulses.
- supply the high voltage pulses to the spark plugs.
The 6 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.
