Millenia 2.3L

The distributorless ignition system uses a camshaft position sensor to control ignition timing. Six individual ignition coils are used, one located on each spark plug.

The camshaft position sensor, located at right front of engine, monitors TDC of cylinder No. 1 and crankshaft angle at 180-degree intervals. Signals created by camshaft position sensor are sent to PCM.

PCM delivers ignition signals to the ignitor to control ignition. Ignitor triggers appropriate ignition coil. Power for ignition coils is supplied from ignition switch.
