What Are The Steps To Reset Dodge Charger Check Engine Light? (2023)

Dodge Charger Check Engine Light Reset Guide

Resetting the Dodge Charger check engine light is only successful when the fault that triggered the code has been repaired. This guide walks through the diagnostic steps, common Charger-specific codes, and the correct reset procedure so the MIL stays off and readiness monitors complete.

• Coverage: 2006-2024 Charger models (3.6L Pentastar, 5.7L/6.4L Hemi, Hellcat, and Scat Pack variants).
• Required tools: OBD-II scan tool with Mode 06, digital multimeter, spark plug socket, smoke tester (for EVAP leaks).
• Safety: If the MIL flashes, reduce throttle immediately-a flashing light indicates active misfires that can damage the catalytic converter.

Common Charger DTCs Before You Reset

Pre-Reset Checklist

• Scan and record stored, pending, and permanent DTCs plus freeze-frame data (RPM, load, fuel trims, coolant temperature).
• Inspect basics: oil level, intake ducting, vacuum hoses, battery voltage, and grounds.
• Confirm repairs with a road test-monitor fuel trims (within +/-5%) and misfire counters in Mode 06.
• Check for TSBs or recalls related to the stored code; update PCM software if applicable.
• Verify no new pending codes appear during a short drive before clearing the MIL.

How to Reset the Charger MIL Properly

1. Ignition ON: Switch to RUN without starting the engine.
2. Connect scan tool: Read current and pending codes, save a diagnostic report.
3. Clear codes: Use the scan tool’s Clear Codes (Mode $04$) function; confirm the MIL turns off.
4. Start and observe: Listen for abnormal idle, check for warning messages, and confirm charging voltage (13.5-14.7 V).
5. Drive cycle: Perform 30-50 miles of mixed driving-steady highway cruise, deceleration, and stop-and-go-to reset EVAP, O2, and catalyst monitors.
6. Re-scan: Ensure no pending or permanent codes remain and that readiness monitors report COMPLETE.

Battery disconnects should be a last resort; they erase transmissions shift adapts, throttle learn, and can create new drivability complaints.

If the Light Returns

• Review freeze-frame data to match the conditions that triggered the fault (ambient temperature, load, speed).
• Check the harness for rubbing or heat damage near known failure points (coil connectors, EVAP lines behind the left rear wheel, O2 sensor wiring).
• Scope sensor signals (cam/crank, O2, MAF) to catch intermittent dropouts that scan tools might miss.
• Inspect aftermarket modifications (intake, exhaust, tuner) that could skew sensor readings; restore stock calibration if needed.

Preventive Maintenance Tips

• Replace spark plugs at the factory interval (often 30,000 miles for Hemi copper plugs).
• Keep the PCV system and throttle body clean to stabilize idle airflow.
• Use top-tier fuel and monitor oil level; low oil can trigger VVT-related codes.
• Update PCM/TCM software per Stellantis bulletins to fix false MIL triggers.
• Inspect EVAP lines and gas cap seal during every oil change.

When to Involve a Professional

Seek professional diagnostics if the MIL returns immediately, the vehicle enters limp mode, or you suspect PCM/TCM software issues. Skilled technicians can perform pinpoint testing, module programming, and smoke diagnostics to prevent repeat faults.
