Why This Matters / Understanding the Problem

You’re driving your 2013 Dodge Charger when suddenly—ping—the check engine light flashes on. It’s not just annoying; it’s a warning that something’s off under the hood. Ignoring it could lead to costly repairs or even safety risks. That’s why knowing how to reset check engine light on 2013 Dodge Charger in 2026 is a must-have skill for every owner.

The check engine light (CEL) is part of your car’s onboard diagnostics (OBD-II) system. It monitors engine performance, emissions, and sensors. When it triggers, your Charger stores a diagnostic trouble code (DTC), like P0420 (catalyst efficiency) or P0171 (lean fuel mixture). These codes tell you what’s wrong—but only if you read them.

Resetting the light without fixing the problem is like silencing a smoke alarm while the house burns. But once the issue is resolved, resetting the light is a smart way to confirm repairs worked. In 2026, with stricter emissions laws and tech upgrades, doing this safely and correctly matters more than ever. Whether you’re a DIYer or just want to avoid a dealership fee, this guide walks you through the process—no mechanic degree required.

What You Need

Before diving into how to reset check engine light on 2013 Dodge Charger in 2026, gather these tools and materials. Most are affordable or already in your garage.

• OBD2 Scanner: A basic code reader (like the BlueDriver or Autel MaxiCOM) costs $30–$60. Avoid cheap no-name brands—they may not clear codes properly.
• Owner’s Manual: For your Charger’s fuse box layout and battery specs.
• Wrench Set: 10mm socket and ratchet (for disconnecting the battery).
• Safety Gloves: Protect your hands when handling battery cables.
• Multimeter (Optional): To check battery voltage before/after.
• Pen and Paper or Phone: To jot down DTCs before clearing them.

Pro tip: If you don’t have an OBD2 scanner, many auto parts stores (like AutoZone, O’Reilly) offer free code reading. Just bring your Charger in—they’ll hook up their scanner, tell you the code, and even clear it if the issue is fixed.

Step-by-Step Guide to How to Reset Check Engine Light on 2013 Dodge Charger in 2026

Step 1: Diagnose the Problem First (Don’t Skip This!)

Resetting the light without knowing the cause is risky. A flashing CEL means a serious issue (like misfires) that can damage the engine. A solid light is less urgent but still needs attention.

1. Turn the ignition to “ON” (don’t start the engine).
2. Plug your OBD2 scanner into the port (usually under the dash, near the steering wheel).
3. Press “Read Codes” and note the DTC (e.g., P0171, P0420).
4. Use the scanner’s description or search online to understand the issue.

Warning: If the code indicates a misfire (P0300–P0308), catalytic converter damage (P0420), or fuel system failure (P0171), fix the problem first before resetting. Driving with these can lead to expensive repairs.

For example, a P0171 (lean fuel mixture) might mean a vacuum leak or dirty fuel injectors. A P0420 could signal a failing catalytic converter. Only reset the light after repairs.

Step 2: Fix the Underlying Issue

This step is non-negotiable. Here are common fixes for frequent 2013 Charger CEL codes:

• Gas Cap Loose or Damaged: Tighten it. If cracked, replace it ($15–$30).
• Oxygen (O2) Sensor Failure: Replace the faulty sensor (cost: $100–$250).
• Mass Airflow (MAF) Sensor Dirty: Clean with MAF-safe spray (not carb cleaner!).
• Spark Plug/Ignition Coil Issues: Replace worn plugs or faulty coils.
• EVAP System Leak: Check hoses and purge valve. Use a smoke machine for hard-to-find leaks.

Once fixed, drive the Charger for 50–100 miles. The car’s computer needs time to “relearn” and confirm the problem is gone. If the light stays off, you’re ready to reset it permanently.

Step 3: Use an OBD2 Scanner to Clear the Code

This is the most reliable method for how to reset check engine light on 2013 Dodge Charger in 2026. It ensures the code is fully erased from the ECU.

1. Park the car on a level surface and turn it off.
2. Plug the OBD2 scanner into the port (under the steering column).
3. Turn the ignition to “ON” (no need to start the engine).
4. Select “Clear Codes” or “Erase DTCs” on the scanner.
5. Confirm the action when prompted.
6. Wait 10–15 seconds. The scanner will display “Codes Cleared” or “No DTCs.”

The check engine light will turn off immediately. If it flickers or comes back, the issue wasn’t fully fixed.

Pro Tip: After clearing, drive for 10–15 minutes. The ECU runs a “drive cycle” to verify everything is working. If the light returns, the problem persists—don’t ignore it.

Step 4: Battery Disconnect Method (Alternative)

If you don’t have an OBD2 scanner, you can reset the light by disconnecting the battery. But this method is less reliable and may reset other systems (like radio presets, clock, and seat memory).

1. Turn the car off and remove the key.
2. Open the hood and locate the 12V battery (driver’s side, near the fender).
3. Put on gloves. Use a 10mm wrench to loosen the negative terminal (black, marked “–”).
4. Remove the negative cable and tuck it away (don’t let it touch metal).
5. Wait 15–30 minutes. This drains residual power from the ECU, clearing stored codes.
6. Reconnect the negative terminal and tighten it.
7. Start the car. The check engine light should be off.

Warning: This method may not work on newer systems (post-2010). The 2013 Charger’s ECU might retain codes even after a battery disconnect. Also, expect to re-sync your radio, windows, and climate control.

Step 5: Drive to Confirm the Reset

Don’t assume the reset worked just because the light is off. Drive for at least 10–15 minutes, including highway speeds. This triggers the ECU’s “readiness monitors” to run tests.

• If the light stays off, success! The issue is resolved.
• If the light returns, the problem wasn’t fully fixed. Use the OBD2 scanner to read the new code.

For example, if you fixed a gas cap leak but the light comes back, there might be a deeper EVAP issue. Don’t reset it again—fix the real problem.

Step 6: Reset Without Fixing (Not Recommended)

Some people reset the light without fixing anything—maybe before a smog check or to hide a problem. This is risky and often illegal in states with emissions testing.

If you must (e.g., temporary issue like bad gas), use the OBD2 scanner to clear the code. But:

• The light will likely return after a few drive cycles.
• The ECU stores “pending” codes even if the light is off.
• Mechanics or smog techs can still see stored codes.

For how to reset check engine light on 2013 Dodge Charger in 2026, always prioritize safety and compliance over shortcuts.

Pro Tips & Common Mistakes to Avoid

Even simple tasks like resetting the CEL can go wrong. Here’s how to do it right—and what to skip.

Pro Tip 1: Use a high-quality OBD2 scanner. Cheap ones may clear the light but leave “pending” codes. A good scanner (like BlueDriver) shows both stored and pending codes, so you know if the fix worked.

Pro Tip 2: After a battery disconnect, reset your radio presets and re-calibrate the windows. On the 2013 Charger, roll each window up and hold the button for 10 seconds to re-sync.

Pro Tip 3: Keep a log of DTCs. Note the code, date, and fix. This helps spot recurring issues (e.g., a failing O2 sensor every 6 months).

Common Mistakes:

• Ignoring a Flashing Light: A flashing CEL means “stop now.” Driving can melt the catalytic converter.
• Clearing Codes Before Reading Them: You lose the clue to the problem. Always read first!
• Overusing the Battery Disconnect Method: It resets the ECU’s “readiness monitors,” which you need for smog checks. Some states require all monitors to be “ready.”
• Using the Wrong OBD2 Port: The 2013 Charger has one port—under the dash, near the steering wheel. Don’t confuse it with the fuse box or glove compartment.
• Not Tightening the Battery Terminal: A loose terminal can cause electrical issues or prevent the reset.

FAQs About How to Reset Check Engine Light on 2013 Dodge Charger in 2026

Q1: Can I reset the check engine light without an OBD2 scanner?

Yes, but it’s less reliable. The battery disconnect method works sometimes, but the 2013 Charger’s ECU may retain codes. An OBD2 scanner is the best tool for how to reset check engine light on 2013 Dodge Charger in 2026.

Q2: How long does the check engine light stay off after resetting?

If the issue is fixed, it should stay off permanently. But if the problem returns (e.g., a loose gas cap), the light will come back after 1–2 drive cycles. The ECU needs time to detect the issue again.

Q3: Will disconnecting the battery erase my radio presets?

Yes. On the 2013 Charger, you’ll lose radio stations, clock time, and window auto-up/down settings. Re-sync them after reconnecting the battery.

Q4: Can I pass smog with a reset check engine light?

Not always. Smog tests check both the light and “readiness monitors.” If you reset the light via battery disconnect, the monitors may show “not ready,” causing a fail. Drive 100–200 miles after fixing the issue to complete the monitors.

Q5: Why does the check engine light come back after resetting?

The problem wasn’t fully fixed. For example, if you cleared a P0420 (catalyst efficiency) code but the catalytic converter is still failing, the light will return. Use the OBD2 scanner to confirm the fix.

Q6: Is it safe to drive with the check engine light on?

Only if it’s solid and you’re close to a repair shop. A flashing light means stop immediately. Driving with a flashing CEL can cause engine or catalytic converter damage.

Q7: Can I use a free auto parts store scanner to reset the light?

Yes! Stores like AutoZone, O’Reilly, and Advance Auto Parts offer free code reading and clearing. They’ll plug in their scanner, tell you the code, and clear it if the issue is fixed. Just don’t abuse the service—they’re helping, not replacing mechanics.
