Detection Condition

DTC P0350 indicates PCM did not receive a valid Ignition Diagnostic Monitor (IDM) pulse signal. This indicates primary side of ignition coil has failed from the ignition module (integrated in PCM) which is caused by an ignition coil primary or secondary circuit malfunction.

• 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 the respective (paired cylinder) spark plugs. Spark plugs are fired simultaneously and are paired so one fires on the compression stroke, while the other spark plug fires on the exhaust stroke. On the subsequent firing of ignition coil, paired cylinder spark plugs will fire on opposite piston strokes.
