Circuit Description

The electronic ignition system uses an individual ignition coil for each cylinder. The PCM controls ignition operation through 6 Ignition Control (IC) circuits. Each ignition coil is connected to PCM, power or ground by following circuits: The ground, ignition 1 voltage and appropriate IC control circuit.

PCM triggers an ignition coil by grounding appropriate IC control circuit using information from Crankshaft Position (CKP) and Camshaft Position (CMP) sensors. See Figure or Figure .
