Well heres what alldata said looked it up while i was at work. Im not for sure if i really understand what the chiltons manual asks ive never been a fan of em for much. Btw how many miles are on your car?
Ford does not provide standalone testing or resistance specifications for this component, the only test provided by Ford for the Coil Pack is a pinpoint test procedure. For diagnosis and testing of the ignition coil
The ignition coil, which is mounted on the upper intake manifold, can be described as a coil pack containing three separate coil units. Each coil unit is individually controlled by the Powertrain Control Module (PCM)
through separate wire leads. Each coil unit activates two spark plugs
wired in a series by the spark plug wires.[*]One spark plug
activates on the compression stroke and uses the majority of the ignition coil's stored energy.[*]The other spark plug
activates on the exhaust stroke and uses very little of the ignition coil's stored energy.[*]Because the pairs of spark plugs
are connected in a series, one spark will travel from ground to the electrode while the other spark will travel from the electrode to ground.[/ul]The spark plug
:[*]changes the high voltage pulse into a spark which ignites the fuel and air mixture.[*]originally equipped on the vehicle has a platinum-enhanced active electrode for long life.[/ul]The Crankshaft Position (CKP)
Initial engine ignition timing
is set at 10 degrees ±2 degrees
Before Top Dead Center (BTDC)
and is not adjustable.
[*]is a variable reluctance sensor triggered by a 36-minus-1 tooth trigger pulse wheel located on the crankshaft inside the engine front cover.[/ul]The sine wave type signal generated from the crankshaft position sensor
provides two types of information:[*]position of the crankshaft in 10 degree
increments[*]the crankshaft speed (rpm)[/ul]The Powertrain Control Module (PCM) uses this information to determine ignition coil turn ON and turn OFF times and misfire detection.
