Ford Mustang (1999-2004) Service Manual / Engine / Engine Ignition - 4.6L (4V) / 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)
