Diagnostic Aids

DTC P0336 can be caused by secondary components leaking high voltage into the Ignition Control (IC) module. Inspect for the following conditions:

• Incorrect harness routing near secondary ignition components.
• Ignition coil arcing to wiring harness or IC module, inspect ignition coils for cracks, carbon tracking, or other signs of damage.
• Secondary ignition wires arcing to wiring harness.
• If the DTC is determined to be intermittent, see INTERMITTENTS in TROUBLE SHOOTING - NO CODES - 3.4L AZTEK & RENDEZVOUS article.
