Components

The crankshaft position sensor:
^ is a variable reluctance sensor.
^ is triggered by a 36-minus-1 tooth trigger wheel mounted on the crankshaft.
^ provides base timing and crankshaft speed (RPM) to the Powertrain Control Module (PCM). Refer to Computers and Control Systems for removal and installation of the crankshaft position sensor.







The eight separate ignition coils:
^ change low voltage signals from the powertrain control module to high voltage pulses.
^ produce the high voltage pulses to the spark plugs.
^ are connected directly to each spark plug.







The spark plugs:
^ change a high voltage pulse into a spark which ignites the fuel and air mixture.
^ originally equipped on the vehicle have a platinum-enhanced electrode for long life.
