Circuit / System Description
The ignition system on this engine uses an individual ignition coil for each cylinder. The engine control module (ECM) controls the spark event for each cylinder through 8 individual ignition control (IC) circuits. When the ECM commands the IC circuit ON, electrical current will flow through the primary winding of the ignition coil, creating a magnetic field. When a spark event is requested, the ECM will command the IC circuit OFF, interrupting current flow through the primary winding. The magnetic field created by the primary winding will collapse across the secondary coil winding, producing a high voltage across the spark plug electrodes. The ECM uses information from the crankshaft position (CKP) and the camshaft position (CMP) sensor for sequencing and timing of the spark events. Each ignition coil/module has the following circuits:
An ignition?1 voltage circuit
A ground circuit
An IC circuit
A low reference circuit
If the ECM detects that the IC circuit has an incorrect voltage level, DTC?P0351-P0358 will set.
