How to Reset the Check Engine Light on a Dodge Journey
The only reliable way to clear the MIL on a Dodge Journey is to repair the underlying issue and use a scan tool. Follow these steps:
- Scan the Journey’s PCM/TCM; record DTCs and freeze-frame data.
- Diagnose the fault (common codes include P0456 EVAP leaks and P030x misfires). Repair the root cause.
- Verify the fix by monitoring fuel trims, misfire counters and sensor data.
- Use a scan tool’s Mode $04$ function to clear the MIL. Avoid disconnecting the battery—it only wipes adaptive values.
- Drive 30–50 miles of mixed city/highway to reset readiness monitors, then re-scan to ensure no new codes appear.
