Ford Mustang Service Manual: Engine Ignition (Description and Operation)
Engine Ignition (Description and Operation)
Eight separate ignition coils:
- are controlled by the powertrain control module (PCM).
- are mounted directly above each spark plug.
- are controlled by the powertrain control module for correct firing sequence.
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.
The crankshaft position (CKP) sensor:
NOTE: Initial engine ignition timing is set at 10 degrees +- 2 degrees before top dead center (BTDC) and is not adjustable. For additional information, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual.
- is a variable reluctance sensor, triggered by a 36-minus-1 tooth trigger pulse wheel located on the crankshaft, inside the engine front cover.
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)
Engine Ignition (DIAGNOSIS AND TESTING)
