Resetting the service engine light on your 2013 Dodge Charger can be done manually or with an OBD2 scanner after repairs. This guide walks you through safe, step-by-step methods to clear the light and ensure your vehicle runs smoothly.
Quick Answers to Common Questions
Can I reset the service engine light without a scanner?
Yes, you can try disconnecting the battery or using the ignition cycle method, but these aren’t always reliable. An OBD2 scanner is the best option.
Will resetting the light improve gas mileage?
Only if the underlying issue (like a faulty oxygen sensor) was affecting fuel efficiency. Resetting alone won’t improve mileage.
How long does it take for the light to reset?
With a scanner, it’s instant. With a battery disconnect, it may take 15 minutes to several hours, depending on the system.
Can I reset the light at home?
Absolutely! All methods described in this guide can be done at home with basic tools.
What if the light flashes instead of staying solid?
A flashing light indicates a severe misfire that can damage the catalytic converter. Stop driving immediately and seek repairs.

Why Is the Service Engine Light On?

Before you reset the light, it’s crucial to understand why it turned on in the first place. The service engine light—also known as the check engine light—is part of your vehicle’s onboard diagnostics system (OBD2). It monitors engine performance, emissions, and other critical systems.
When a sensor detects an anomaly, the computer stores a diagnostic trouble code (DTC) and illuminates the light. Common causes include:
– Loose or faulty gas cap
– Oxygen sensor failure
– Mass airflow sensor issues
– Catalytic converter problems
– Spark plug or ignition coil failure
– Exhaust gas recirculation (EGR) valve malfunction
Ignoring the light can lead to reduced fuel efficiency, poor performance, or even engine damage. That’s why diagnosing the issue is the first step—not just resetting the light.
Tools You’ll Need
Depending on the method you choose, you may need one or more of the following:
– OBD2 scanner (basic or advanced)
– Socket wrench set (for battery disconnect)
– Safety gloves and glasses
– Owner’s manual (for reference)
– Pen and paper (to note error codes)
Most modern OBD2 scanners are affordable and easy to use. You can find them online or at auto parts stores for as little as $20.
Method 1: Using an OBD2 Scanner (Recommended)
The safest and most reliable way to reset the service engine light is with an OBD2 scanner. This method allows you to read the error code, confirm the repair, and clear the light—all without risking damage to your vehicle.
Step 1: Locate the OBD2 Port
The OBD2 port in your 2013 Dodge Charger is typically located under the dashboard on the driver’s side. It’s a 16-pin connector, usually black or gray, and may be covered by a small flap. You don’t need any tools to access it—just reach under the steering column and look for the port.
Step 2: Plug in the Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure it’s securely connected. Some scanners power on automatically; others require you to press a button.
Step 3: Turn the Ignition to “On”
Turn the key to the “ON” position (but don’t start the engine). This powers up the vehicle’s computer and allows the scanner to communicate with it.
Step 4: Read the Error Code
Follow the scanner’s instructions to retrieve the diagnostic trouble code (DTC). Common codes for the 2013 Charger include:
– P0455: Large EVAP leak (often a loose gas cap)
– P0171: System too lean (air/fuel mixture issue)
– P0300: Random/multiple cylinder misfire
Write down the code and research it using the scanner’s manual or online resources. This helps you confirm the problem has been fixed.
Step 5: Clear the Code
Once you’ve confirmed the repair is complete, use the scanner’s “Clear Codes” or “Erase DTC” function. The service engine light should turn off immediately.
Step 6: Test Drive
Start the engine and take your Charger for a short drive (5–10 miles). This allows the computer to run self-checks. If the light stays off, the reset was successful.
Method 2: Disconnecting the Battery
If you don’t have an OBD2 scanner, you can try resetting the light by disconnecting the battery. This method forces the vehicle’s computer to reset, clearing stored codes and turning off the light. However, it’s not always reliable and can cause side effects.
Step 1: Turn Off the Engine and Remove the Key
Make sure the car is off and the key is out of the ignition. This prevents electrical surges or damage.
Step 2: Locate the Battery
Open the hood and find the battery. In the 2013 Dodge Charger, it’s usually on the right side of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a socket wrench to loosen the nut on the negative (-) terminal. Remove the cable and secure it away from the battery post. Wait at least 15 minutes—this gives the computer time to reset.
Step 4: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Close the hood.
Step 5: Start the Engine
Turn the key to start the engine. The service engine light may flash briefly, then turn off. If it stays off after a short drive, the reset worked.
Potential Side Effects
Disconnecting the battery can reset other systems, including:
– Radio presets
– Clock settings
– Power window auto-up/down function
– Transmission shift points (may need relearning)
To avoid these issues, consider using a memory saver device that plugs into the OBD2 port or cigarette lighter to maintain power during the reset.
Method 3: Ignition Cycle Method
Some 2013 Dodge Chargers allow you to reset the service engine light using a specific ignition sequence. This method doesn’t require tools but may not work on all models.
Step 1: Turn the Ignition to “On”
Insert the key and turn it to the “ON” position (dashboard lights on, engine off).
Step 2: Press the Gas Pedal
Press the accelerator pedal all the way down and hold it for 3 seconds.
Step 3: Turn the Ignition Off
Release the pedal and turn the key back to “OFF.”
Step 4: Repeat the Cycle
Repeat steps 1–3 two more times (three total cycles).
Step 5: Start the Engine
On the fourth cycle, turn the key to “ON” and start the engine. The service engine light should reset.
Note: This method is not officially documented by Dodge and may not work on all 2013 Chargers. Use it as a last resort.
What to Do If the Light Returns
If the service engine light comes back on after resetting, the underlying issue hasn’t been fixed. Here’s what to do:
Recheck the Repair
Double-check your work. Did you install the correct part? Was the repair done properly? For example, if you replaced an oxygen sensor, ensure it’s the right model and securely connected.
Scan for New Codes
Use your OBD2 scanner to read the new code. It may be different from the original, indicating a related or secondary problem.
Inspect Related Systems
Some issues trigger cascading problems. A faulty mass airflow sensor can cause misfires, which damage the catalytic converter. Address all related components.
Visit a Mechanic
If you’re unsure or the problem persists, consult a certified mechanic. They have advanced tools and expertise to diagnose complex issues.
Troubleshooting Common Issues
Light Won’t Turn Off
If the light remains on after resetting, the problem likely wasn’t fixed. Recheck the repair or scan for codes.
Scanner Won’t Connect
Ensure the ignition is on, the scanner is compatible with OBD2, and the port is clean. Try a different scanner if possible.
Battery Reset Didn’t Work
Some systems require a drive cycle to complete. Drive your Charger for 20–30 miles with varied speeds to allow the computer to recheck systems.
Radio or Clock Reset
After a battery disconnect, re-enter your radio code (found in the owner’s manual or glove box) and reset the clock.
Safety Tips
– Always wear safety gloves and glasses when working under the hood.
– Never disconnect the battery while the engine is running.
– Use only compatible parts and tools.
– Avoid forcing connectors or cables.
– If you’re unsure, seek professional help.
Conclusion
Resetting the service engine light on your 2013 Dodge Charger is a straightforward process—but it should never be done without first addressing the root cause. Whether you use an OBD2 scanner, disconnect the battery, or try the ignition cycle method, always confirm the repair is complete and test drive your vehicle afterward.
Remember, the light is your car’s way of saying, “Something’s wrong.” Ignoring it can lead to costly repairs down the road. By following this guide, you’ll keep your Charger running efficiently and avoid unnecessary stress.
If the light returns, don’t panic—just recheck your work or consult a professional. With the right tools and knowledge, you’ve got this!
