TORQUE SPECIFICATIONS

The electronic ignition (El) system for the 3.0L Duratec engine consists of the following components

1. Crankshaft position (CKP) sensor
2. Camshaft position (CMP) sensor
3. 6 ignition coil-on-plugs
4. 6 spark plugs

The CKP sensor

1. is a variable reluctance sensor.
2. is mounted in the front cover.
3. is triggered by a 36-minus-l tooth trigger wheel located behind the front cover.
4. provides base timing and crankshaft speed (rpm) to the powertrain control module (PCM). For additional information, refer to «ELECTRONIC ENGINE CONTROLS»(/ford/five-hundred/i-2004-2007/remont/removal-installation/#electronic-engine-control-system) .

The CMP sensor

1. is a variable reluctance sensor.
2. is mounted in the front cover.
3. is triggered by the high point mark on the LH exhaust camshaft.
4. provides camshaft rotational location information to the PCM. For additional information, refer to «ELECTRONIC ENGINE CONTROLS»(/ford/five-hundred/i-2004-2007/remont/removal-installation/#electronic-engine-control-system) .

The 6 ignition coil-on-plugs

1. are connected directly to each spark plug.
2. change low voltage signals from the PCM to high voltage pulses.
3. supply the high voltage pulses to the spark plugs.

The 6 spark plugs

1. change high voltage pulses into a spark which ignites the fuel and air mixture.
2. originally equipped on the vehicle have a platinum-enhanced active electrode for long life.

Removal and Installation

1. Remove the upper intake manifold. For additional information, refer to «ENGINE»(/ford/five-hundred/i-2004-2007/remont/mechanical/#engine) .
2. Disconnect the ignition coil electrical connectors.
3. Remove the ignition coil bolts. To install, tighten to 6 Nm (53 lb-in).
4. Remove the ignition coils.
5. To install, reverse the removal procedure. Apply a light film of Silicone Brake Caliper Grease and Dielectric Compound XG-3-A meeting Ford specifications ESE-M1C171-A to the inside of the coil boots before installation.
