TORQUE SPECIFICATIONS
The electronic ignition (El) system for the 3.0L Duratec engine consists of the following components
- ignition-coil-on plug
- spark plug
- crankshaft position (CKP) sensor
- camshaft position (CMP) sensor
The crankshaft position (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).
The camshaft position (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).
