Detection Condition

DTC P0351-P0356 indicate PCM did not receive a valid Ignition Diagnostic Monitor (IDM) pulse signal, which indicates primary side of coil has failed from ignition module (integrated in PCM). This is caused by an ignition coil failure. DTC number indicates cylinder number.

• On 2.0L, coil packs are in a tower configuration with 2 adjacent coil towers sharing a common coil (called a matched pair). On 3.0L, coils are individual and connected directly to each spark plug. For 2.0L applications, matched cylinder pairs are 1 and 4, and 2 and 3. For 3.0L applications, matched cylinder pairs are 1 and 5, 2 and 6, and 3 and 4.
• When ignition coil is fired by PCM, spark is delivered to a matched pair of towers, then onto respective (paired cylinder) spark plugs. Spark plugs are fired simultaneously and are paired so one fires on compression stroke, while other spark plug fires on exhaust stroke. On subsequent firing of ignition coil, paired cylinder spark plugs will fire on opposite piston strokes.
