DISTRIBUTORLESS Ignition System

The distributorless ignition system uses a camshaft position sensor to control ignition timing. Two individual ignition coils are used to send spark to cylinders No. 1 and 4, and cylinders No. 2 and 3. Paired cylinders will spark every complete crankshaft rotation (360 degrees).

The camshaft position sensor, mounted on rear of intake camshaft, 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.
