Step-by-Step Guide to How to Reset Check Engine Light on 2014 Dodge Charger in 2026

There are three main ways to reset the check engine light on your 2014 Dodge Charger. We’ll cover them in order of ease and safety. Method 1 (OBD2 Scanner) is the best choice for most people. Methods 2 and 3 are backups if you don’t have a scanner.

Step 1: Use an OBD2 Scanner (Recommended Method)

This is the most accurate and safest way to reset the check engine light. It also lets you see what’s wrong before you clear it.

1. Locate the OBD2 Port: In your 2014 Charger, it’s under the dashboard, to the left of the steering column. It looks like a small rectangular plug (usually black or gray). You might need to crouch down to see it.
2. Plug in the Scanner: Turn the ignition to “ON” (don’t start the engine). Insert the OBD2 scanner into the port. Most scanners power on automatically.
3. Read the Trouble Codes: Use the menu to select “Read Codes” or “Check Engine.” The scanner will show one or more codes (like P0457 for a gas cap leak). Write them down!
4. Research the Code: Open your phone or tablet. Google the code (e.g., “P0457 2014 Dodge Charger”) to learn the cause. This step is crucial—don’t skip it.
5. Fix the Problem (If Needed): For example:
   • P0457? Tighten or replace the gas cap.
   • P0301? Check cylinder 1 spark plug or coil.
   • P0171? Look for a vacuum leak or bad O2 sensor.
6. Clear the Codes: Once the issue is fixed (or if you’re sure it’s resolved), select “Clear Codes” or “Erase DTCs” on the scanner. Confirm when prompted.
7. Wait and Test: Turn the ignition off, then restart the engine. The check engine light should be off. Drive for 10–15 minutes. If the light stays off, you’re good. If it comes back, the problem isn’t fixed.

Warning: Never clear codes without reading them first. You might erase valuable clues about what’s wrong.

Step 2: Disconnect the Battery (Manual Method)

If you don’t have an OBD2 scanner, you can try resetting the light by disconnecting the battery. This forces the car’s computer to reset—but it also erases all codes, so you won’t know what caused the light.

Only use this method if you’re certain the issue is resolved (e.g., you just tightened the gas cap).

1. Turn Off the Engine: Make sure the car is off and the keys are out of the ignition.
2. Pop the Hood: Release the hood latch inside the car, then open it from the front.
3. Find the Battery: In the 2014 Charger, it’s on the driver’s side, near the fender. It’s a standard 12V battery with two terminals (positive “+” and negative “-”).
4. Disconnect the Negative Terminal:
   • Use a 10mm wrench to loosen the nut on the negative (black, “-”) terminal.
   • Remove the clamp and tuck it aside so it doesn’t touch the battery.
5. Wait 15–30 Minutes: This gives the car’s computer time to drain any stored power. The longer you wait, the more systems reset.
6. Reconnect the Terminal: Reattach the negative clamp and tighten the nut. Don’t overtighten—snug is enough.
7. Turn On the Ignition: Insert the key and turn it to “ON.” The check engine light will flash for a few seconds, then turn off.
8. Start the Engine: The light should stay off. Drive for 10–15 minutes. If it returns, the problem persists.

Pro Tip: After reconnecting the battery, you may need to reset your radio presets, clock, and power windows. Some Chargers also need to relearn throttle position—drive gently for the first 20 miles.

Step 3: Drive It Out (Natural Reset)

Some minor issues (like a loose gas cap) fix themselves after a few drive cycles. The car’s computer monitors systems and automatically clears the light if everything checks out.

1. Drive Normally for 3–5 Cycles: A “drive cycle” means:
   • Start the engine cold (after sitting overnight).
   • Drive at varying speeds (25–55 mph).
   • Include a few minutes of highway driving (if possible).
   • Stop and restart the engine 2–3 times per cycle.
2. Wait 3–5 Days: Complete 3–5 full drive cycles. The car’s computer will test emissions systems and reset the light if no faults are found.
3. Check the Light: After the last cycle, the check engine light should be off. If not, the problem is still there.

Warning: This method only works for minor, temporary issues. If the light returns after going off, use the OBD2 scanner to diagnose the real cause.

Step 4: Verify the Reset (All Methods)

After any reset method, confirm the light is truly off:

1. Check the Dashboard: The check engine light should be off when the engine is running.
2. Use the Scanner Again: Plug it back in. Select “Read Codes.” If it says “No Codes Found” or “No DTCs,” the reset worked.
3. Drive for a Week: Keep an eye on the light. If it stays off, the issue is resolved. If it comes back, you’ll need a deeper diagnosis.

Remember: how to reset check engine light on 2014 Dodge Charger in 2026 isn’t just about clearing the light—it’s about ensuring the problem is fixed for good.

Pro Tips & Common Mistakes to Avoid

Even simple tasks like resetting a check engine light can go wrong. Here’s what to watch for—and how to avoid headaches.

Pro Tips

• Always Read Codes First: Clearing the light without knowing the cause is like turning off a fire alarm without checking for fire. Use your OBD2 scanner to pull codes before resetting.
• Use a Quality Scanner: Cheap $15 scanners work for basic codes, but pricier ones (like BlueDriver) offer real-time data, freeze-frame info, and code descriptions. Worth the investment.
• Check for Multiple Codes: Sometimes, one problem (like a vacuum leak) triggers several codes. Fix the root cause to clear all of them.
• Reset After Repairs: If you replace a sensor or fix a leak, reset the light to confirm the repair worked.
• Keep Records: Save your codes and fixes in a notebook or app. This helps track recurring issues and impresses mechanics.
• Emissions Test Prep: Some states require all monitors to be “ready” for emissions tests. Use your scanner to check monitor status. If not ready, drive for a few more cycles.

Common Mistakes

• Clearing Codes Too Soon: Don’t reset the light right after seeing it. Diagnose first. Example: If the code is P0420 (catalyst efficiency), you might need a new catalytic converter—not just a reset.
• Disconnecting the Wrong Terminal: Always remove the negative terminal first. Removing the positive first can cause sparks or damage electronics.
• Forgetting to Tighten the Gas Cap: A loose cap is the #1 cause of check engine lights. After tightening, drive for 5–10 miles. The light often clears on its own.
• Ignoring the Light After Reset: If the light comes back, stop driving. A persistent code means a serious issue (like a misfire) that can damage the engine.
• Using the Battery Method Too Often: Frequent disconnects can shorten battery life and damage the ECU. Use it only as a last resort.
• Not Testing After Reset: Always drive the car after clearing codes. The computer needs to run tests to confirm everything is working.

Real-Life Scenario: A Charger owner reset the light after a P0457 code (gas cap). The light stayed off for a week—then came back. They tightened the cap again, reset it, and the light returned. Finally, they replaced the cap with a genuine Mopar part. The light stayed off. Moral: Fix the real issue, not just the symptom.

FAQs About How to Reset Check Engine Light on 2014 Dodge Charger in 2026

You’ve got questions—we’ve got answers. Here are the most common ones about resetting the check engine light.

Q: Can I reset the check engine light without a scanner?
