2014 Dodge Charger Check Engine Light Reset Guide
Resetting the MIL (malfunction indicator lamp) on a 2014 Charger without fixing the problem only guarantees the light will return. Use this workflow to diagnose the fault, complete the repair, and clear the light confidently.
- Engines covered: 3.6L V6, 5.7L HEMI, 6.4L SRT8.
- Before you begin: Scan for DTCs, capture freeze-frame data and fuel trims, and confirm battery voltage is healthy.
- Tools: OBD-II scanner with live data, spark tester, smoke tester, fuel pressure gauge, basic hand tools.
Why the Light Comes On
Subsystem | Typical Codes | Likely Cause | First Checks |
---|---|---|---|
Ignition | P0300–P0308 | Faulty coil, worn plug, lifter wear | Swap coils/plugs, listen for valvetrain tick, run compression test. |
EVAP | P0456/P0457 | Loose/damaged gas cap, cracked vent hose | Install OEM cap, smoke-test EVAP lines, inspect ESIM module. |
Throttle | P2110/P0123 | Dirty throttle body, TPS/APP mismatch | Clean throttle plate, check 5 V reference, perform ETC relearn. |
Catalytic | P0420/P0430 | Efficiency drop from misfire or exhaust leak | Fix misfires first, check exhaust joints, monitor O2 sensors. |
Transmission | P0700 + subcodes | Solenoid pack issue, low ATF | Scan TCM, inspect wiring, verify ATF level/condition. |
Reset Procedure
- Scan and document: Capture PCM/TCM codes, freeze-frame data, fuel trims and Mode $06$ misfire counters.
- Repair the fault: Follow the subsystem checks above—swap coils, clean throttle body, repair EVAP leaks, address transmission issues.
- Verify: After the fix, confirm fuel trims and O2 sensors have returned to normal, and no misfire counters increase.
- Clear via scan tool: Use Mode $04$ to reset the MIL. Avoid disconnecting the battery; it only erases adaptives temporarily.
- Drive cycle: Complete 30–50 miles of mixed driving so readiness monitors return to “complete.”
- Re-scan: Ensure no pending or permanent codes remain. If the lamp returns, start the diagnostic flow again.
Frequently Asked Questions
Will a battery disconnect reset the light?
Only temporarily. The PCM will relearn and the MIL will return if the fault persists. Always repair the root cause first.
Is it safe to keep driving with the light on?
A steady MIL means the car can usually be driven short distances while planning repairs. A flashing MIL indicates a severe misfire—reduce throttle and fix it immediately.
How long do monitors take to reset after clearing?
Plan for 30–50 miles of city/highway driving. Use your scan tool to confirm monitors have returned to “complete.”
Preventive Maintenance Tips
- Replace spark plugs and inspect coils every 30k miles (5.7L) / 60k miles (6.4L); torque to spec.
- Clean the throttle body annually to avoid correlation errors.
- Inspect EVAP hoses, ESIM module and fuel cap seals yearly.
- Keep PCM/TCM software updated; Chrysler flashes often refine misfire and EVAP diagnostics.
