Common Chrysler Issue: Dtc Monitor Drive Cycle Reset Needed

Make: Chrysler | Model Example: 2010 300 | Avg. Mileage: 108547 | Job Number: 495388

Repair Issue:

DTC Monitor Drive Cycle Reset Needed

Cause:

Canister Purge Solenoid – Evaporative Rubber Hose Connectors – Evaporative System Integrity Monitor (ESIM) Assembly – Fuel Filler Cap – Fuel Tank – Fuel Tank Filler Neck

Customer Concern:

Code P0456, P0457.

Test/Procedure:

1. Unplug the evaporative hose from the charcoal canister assembly. Install the smoke machine into that hose. Smoke test the system with the engine off. The system should be sealed from the canister to the canister purge solenoid. Be sure to remove the hose that runs from the engine to the canister purge solenoid to check for smoke in that hose. If no leaks are found, replace the charcoal canister/Evaporative System Integrity Monitor (ESIM).
2. The “gas cap” light cannot be reset by the scan tool. The PCM has to complete and pass a leak test in order for the light to shut off. Drive the vehicle 16-20 miles. After the road test, shut the vehicle off and park it overnight. If the system passes a leak test, the “gas cap” light will shut off on the next key cycle. If the light does not go off, recheck for fault codes.

Tech Tip

Perform Smoke Test Procedure in Tests/Procedures.

Important Take-A-Way:

By leveraging the smoke test, automotive techs can save time and quickly identify if there are any leaks and the locations.
