How to Reset Check Engine Light on a 2014 Dodge Dart: A Complete Guide
Have you ever been driving your 2014 Dodge Dart when suddenly—bam!—the check engine light appears on the dashboard? It’s one of those moments that makes every driver pause, heart skip a beat, and wonder: “What now?” The good news? You’re not stuck at a mechanic’s shop right away. In fact, many times, you can reset the check engine light yourself—but only after addressing the root cause.
This guide will walk you through everything you need to know about diagnosing and resetting the check engine light on your Dodge Dart. Whether you’re a seasoned DIYer or a first-time car owner, we’ll keep things simple, safe, and effective. By the end, you’ll feel confident handling this common issue without spending a fortune on repairs.
Understanding the Check Engine Light
The check engine light (CEL) is your car’s way of saying, “Hey, something might be wrong.” It’s part of the On-Board Diagnostics II (OBD2) system, which monitors emissions, engine performance, and more than 50 different vehicle systems. When a problem is detected, the computer stores a trouble code—a numeric code that tells you what’s going on.

In the case of a 2014 Dodge Dart, the CEL could indicate anything from a loose gas cap to a faulty oxygen sensor. But here’s the key: resetting the light doesn’t fix the problem. It simply clears the warning so the light turns off. That’s why it’s important to first identify and resolve the issue before resetting.
Step-by-Step: How to Reset the Check Engine Light
Method 1: Use an OBD2 Scanner (Recommended)
This is the safest and most accurate way to diagnose and reset your Dodge Dart’s check engine light. An OBD2 scanner plugs into your car’s diagnostic port and reads the stored trouble codes.
Step 1: Locate the OBD2 Port
The OBD2 port in your 2014 Dodge Dart is usually found under the dashboard on the driver’s side. Look near the steering column—it’s a small, oval-shaped connector, often covered by a plastic flap labeled “Diagnostics” or “OBD2.”
Step 2: Turn Off the Engine
Make sure your car is parked, the transmission is in park (or neutral), and the ignition is off. This prevents any electrical interference while scanning.
Step 3: Plug in the OBD2 Scanner
Insert the scanner’s cable firmly into the port until it clicks. Most scanners have a power button—press it to turn on the device.
Step 4: Read the Trouble Codes
Follow the scanner’s instructions to connect to your vehicle. Once connected, it will display one or more trouble codes (like P0300 or P0420). Write these down—they’re critical for identifying the issue.
Step 5: Address the Problem (If Possible)
For example:
- P0446: Evaporative Emission Control System Malfunction—often due to a loose or missing gas cap.
- P0300: Random/Multiple Cylinder Misfire Detected—could mean bad spark plugs or fuel injectors.
- P0420: Catalyst System Efficiency Below Threshold—indicates a failing catalytic converter.
Once you’ve fixed the issue (e.g., tighten the gas cap or replace a sensor), proceed to reset.
Step 6: Clear the Codes
On most scanners, select “Erase Codes” or “Clear DTCs” from the menu. Confirm the action. The scanner will communicate with your car’s computer and delete the stored codes. After a few seconds, the check engine light should blink once and then stay off.
Step 7: Verify the Reset
Turn the ignition to “ON” (don’t start the engine). Watch the dashboard—if the light remains off, the reset was successful. If it comes back on within minutes, there’s still an active fault.
Method 2: Disconnect the Battery (Quick Fix, Not Recommended)
If you don’t have a scanner, disconnecting the battery will clear the memory of the car’s computer—including the check engine light. However, this method has drawbacks.
Step 1: Park Safely
Ensure your car is off, parked on level ground, and the parking brake is engaged.
Step 2: Remove the Negative Battery Cable
Locate the negative terminal (marked with a minus sign “–”) on your battery. Use a wrench to loosen the nut and carefully lift the black cable off the post. Do not touch the cable to the positive terminal or battery post to avoid sparks.
Step 3: Wait 10–15 Minutes
This allows the car’s computer (ECU) to fully discharge. While waiting, note that this method will also reset:
- Radio presets
- Clock settings
- Tire pressure monitoring system (TPMS) calibrations
- Some drivetrain adaptations
Step 4: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Start the engine—the check engine light should be off.
Important Note:
If the light returns within a day or two, the underlying issue wasn’t resolved. Continuing to drive with an unresolved fault can damage your engine or exhaust system over time.
Method 3: Drive It Off (Automatic Reset)
Modern cars like the 2014 Dodge Dart are designed to self-correct in some cases. If the issue was minor (like a temporary sensor glitch), the car may turn off the light after several drive cycles (short trips where the engine reaches operating temperature).
To try this:
- Drive normally for at least 20–30 minutes per trip.
- Avoid short trips that don’t allow the engine to warm up.
- Keep an eye on the light—if it stays off after 3–5 drives, the problem may have cleared itself.
However, don’t rely solely on this method if the light came on due to a serious issue.
Troubleshooting Common Issues
Why Won’t My Check Engine Light Stay Off?
If the light returns immediately after resetting, the fault is likely still present. Use an OBD2 scanner to re-check for active codes. Persistent issues may require professional diagnostics, especially for engine or transmission problems.
My Gas Cap Was Tight, Why Is the Light Still On?
Sometimes the cap isn’t sealing properly—even if it looks tight. Try removing and re-tightening it. Also, inspect the rubber gasket inside the cap for cracks or debris. Replace the cap if damaged.
I Don’t Have an OBD2 Scanner—What Now?
Many auto parts stores (like AutoZone, Advance Auto Parts, or O’Reilly) offer free check engine light scans. Just bring your vehicle in, and they’ll read the codes at no cost. This is a great first step before buying a scanner.
Can I Ignore the Check Engine Light?
While you might be tempted to ignore it temporarily, doing so risks:
- Reduced fuel economy
- Increased emissions
- Potential damage to catalytic converters or sensors
- Failed state inspections in some areas
It’s always best to investigate—even if just to rule out simple fixes.
Preventing Future Check Engine Lights
The best way to avoid constant check engine lights is regular maintenance. Here’s how:
- Change oil and filters every 5,000–7,500 miles.
- Replace spark plugs around 100,000 miles.
- Check and replace air filters annually.
- Tighten the gas cap securely after refueling.
- Use high-quality fuel and avoid running on empty.
Also, invest in an OBD2 scanner for future peace of mind. Entry-level models start around $20 and can save you hundreds in unnecessary repairs.
When to See a Professional
While many 2014 Dodge Dart issues are simple, some require expert attention:
- If the check engine light flashes repeatedly—this indicates a severe misfire that can damage the catalytic converter.
- If multiple codes appear or the same code returns after resetting.
- If you smell burning, notice smoke, or hear unusual noises.
In these cases, visit a certified technician or dealership. They have advanced tools and training to handle complex diagnostics.
Conclusion
Resetting the check engine light on your 2014 Dodge Dart doesn’t have to be stressful. With the right approach—whether using an OBD2 scanner, briefly disconnecting the battery, or driving it off—you can regain control of your dashboard warnings. But remember: resetting is not fixing. Always aim to identify and resolve the underlying cause.
By following this guide, you’re taking a smart, proactive step toward maintaining your vehicle’s health. And who knows? You might just save yourself a trip to the mechanic—and a big bill.
Stay safe, stay informed, and happy driving!
