Diagnostic Aids
- If DTC P0336 is set, diagnose that DTC first. An intermittent fault in the CKP circuit will cause the ECM to resync the cam and may set DTC P0341.
- An intermittent short to voltage on the CMP signal circuit can set this DTC. A direct short to voltage on the CMP signal circuit will set DTC P0340, as there will be no change in the cam signal input.
- The following conditions may set this DTC:
- High resistance in the #1 secondary ignition system
- Low resistance in the #4 secondary ignition system
- Corroded or loose #1 or #4 secondary ignition components
- Harness being routed too close to the secondary ignition components, relays, motors
- If this DTC is determined to be intermittent, refer to Testing for Intermittent Conditions and Poor Connections
