DTC P0351-P0358
Circuit / System Description
The ignition system on this engine uses an individual coil/module for each cylinder. The engine control module (ECM) controls the spark event for each cylinder through the eight individual ignition control circuits. When the ECM commands the ignition control 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 ignition control circuit OFF, interrupting current flow through the primary winding. The magnetic field created by the primary winding will collapse across the secondary coil windings, producing a high voltage across the spark plug electrodes. The ECM uses information from the crankshaft position sensor, and the camshaft position sensor for sequencing and timing of the spark events. Each ignition coil/module assembly has the following circuits:
Ignition voltage
Ground
Ignition control
Low reference
If the ECM detects that the ignition control circuit has an incorrect voltage level, DTC?P0351-P0358 will set.
