Before we jump into resetting the light, it’s important to understand why it illuminated in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your Durango’s onboard diagnostics system (OBD2). This system constantly monitors engine performance, emissions, fuel efficiency, and various sensors. When it detects a problem that could affect emissions or engine operation, it triggers the light and stores a diagnostic trouble code (DTC).
Common reasons the check engine light appears on a 2014 Durango include:
- Loose or faulty gas cap: This is one of the most frequent causes. A loose cap allows fuel vapors to escape, triggering an evaporative emissions system fault.
- Oxygen (O2) sensor failure: These sensors monitor exhaust gases and help regulate fuel mixture. A failing sensor can reduce fuel economy and increase emissions.
- Catalytic converter issues: Over time, the catalytic converter can become clogged or damaged, leading to reduced performance and increased emissions.
- Mass airflow (MAF) sensor problems: This sensor measures how much air enters the engine. If it’s dirty or malfunctioning, it can cause poor acceleration and rough idling.
- Spark plug or ignition coil failure: Worn spark plugs or faulty coils can lead to misfires, which the OBD2 system detects immediately.
- Exhaust gas recirculation (EGR) valve issues: A stuck or clogged EGR valve can cause rough idling and increased emissions.
Understanding the cause helps you fix the problem—not just hide the symptom. Resetting the light without addressing the issue is like turning off a smoke alarm while your kitchen is on fire. It might make you feel better temporarily, but the real danger remains.
Tools You’ll Need
Before attempting to reset the check engine light, gather the right tools. Depending on the method you choose, you may need:
- OBD2 scanner: A handheld device that plugs into your Durango’s diagnostic port to read and clear trouble codes. Affordable models start around $20 and are available online or at auto parts stores.
- Owner’s manual: Your 2014 Durango manual contains valuable information about the dashboard lights, fuse box location, and reset procedures.
- Basic hand tools: A wrench or socket set may be needed if you plan to disconnect the battery.
- Pen and paper: To write down trouble codes before clearing them, in case you need to reference them later.
Having these items ready will make the process smoother and help you avoid mistakes.
Method 1: Use an OBD2 Scanner (Recommended)
The most accurate and safest way to reset the check engine light on your 2014 Durango is by using an OBD2 scanner. This method allows you to read the trouble codes, understand what’s wrong, and clear the light—all without guessing.
Step 1: Locate the OBD2 Port
In the 2014 Durango, the OBD2 diagnostic port is typically located under the dashboard on the driver’s side, near the steering column. It’s a 16-pin connector that looks like a trapezoid-shaped plug. You may need to crouch down or use a flashlight to find it. It’s usually within easy reach—no tools required.
Step 2: Turn Off the Engine
Make sure your Durango is completely off before plugging in the scanner. This prevents any electrical interference and ensures a clean connection.
Step 3: Plug in the OBD2 Scanner
Insert the scanner’s connector into the OBD2 port. It should fit snugly—don’t force it. Once connected, turn the ignition to the “ON” position (but don’t start the engine). This powers up the scanner and allows it to communicate with the vehicle’s computer.
Step 4: Read the Trouble Codes
Follow the scanner’s on-screen prompts to read the diagnostic trouble codes (DTCs). Most scanners will display codes like P0455 (large evaporative leak) or P0171 (system too lean). Write these down. You can look them up online or use the scanner’s built-in code library to understand what each one means.
For example, a P0420 code typically indicates a problem with the catalytic converter’s efficiency. A P0300 code means random/multiple cylinder misfires. Knowing the code helps you decide whether you can fix it yourself or need a mechanic.
Step 5: Fix the Underlying Issue
Before clearing the light, address the problem. If the code points to a loose gas cap, tighten it or replace it. If it’s an O2 sensor, you may need to purchase and install a new one. For more complex issues like catalytic converter failure, professional help is recommended.
Step 6: Clear the Codes
Once the issue is resolved, use the scanner to clear the trouble codes. Most scanners have a “Clear Codes” or “Erase DTCs” option. Select it, and the check engine light should turn off. If the scanner confirms the codes are deleted, you’re good to go.
Step 7: Test Drive
Start your Durango and take it for a short drive. The light should stay off. If it comes back on within a day or two, the problem may not be fully fixed, or a new issue has arisen.
Method 2: Complete a Driving Cycle
Sometimes, after a repair, the check engine light turns off on its own after you complete a specific driving pattern known as a “driving cycle.” This allows the vehicle’s computer to recheck all monitored systems and confirm everything is working properly.
The 2014 Durango uses an OBD2 system that runs self-tests during certain driving conditions. If all tests pass, the computer will automatically turn off the check engine light—no scanner needed.
What Is a Driving Cycle?
A driving cycle is a sequence of driving maneuvers that trigger the vehicle’s onboard diagnostics to run emissions and performance tests. For the 2014 Durango, a typical driving cycle includes:
- Cold start: Start the engine when it’s been off for at least 8 hours (overnight).
- Idle for 2–3 minutes to allow the engine to warm up.
- Drive at 30–40 mph for about 5 minutes with steady acceleration.
- Accelerate to 55–60 mph and maintain speed for 3–5 minutes.
- Decelerate gradually (without braking hard) and come to a stop.
- Repeat the cycle 2–3 times over the course of a day.
This pattern helps the computer test systems like the catalytic converter, oxygen sensors, and evaporative emissions.
How Long Does It Take?
Depending on the issue, it may take one full driving cycle or several over a few days for the light to turn off. Be patient—rushing or skipping steps can prevent the system from completing its checks.
Tip: Use a Scanner to Monitor Progress
Even if you’re not clearing codes, you can use an OBD2 scanner to check if the “monitors” (self-tests) are completing. Look for “Ready” or “Not Ready” status for each monitor. Once all are “Ready,” the light is more likely to turn off.
Method 3: Disconnect the Battery (Use with Caution)
Disconnecting the battery is a quick way to reset the check engine light, but it comes with risks. This method forces the vehicle’s computer to reset by cutting power, which clears temporary memory—including trouble codes.
Step 1: Turn Off the Engine and Remove the Key
Make sure the Durango is completely off and the key is out of the ignition.
Step 2: Locate the Battery
The battery is under the hood on the driver’s side. It’s a standard 12-volt lead-acid battery with positive (+) and negative (-) terminals.
Step 3: Disconnect the Negative Terminal
Use a wrench or socket to loosen the nut on the negative (black) battery cable. Carefully remove the cable and tuck it away from the terminal so it doesn’t accidentally touch metal.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer to fully reset. Some recommend up to 30 minutes for a complete reset.
Step 5: Reconnect the Battery
Reattach the negative cable and tighten the nut securely. Make sure it’s snug but don’t overtighten.
Step 6: Start the Vehicle
Turn the ignition to “ON” and wait a few seconds before starting the engine. The check engine light may flash briefly, then turn off.
Risks and Drawbacks
While this method works, it has downsides:
- Loss of radio settings: You may need to re-enter your radio presets and clock time.
- Adaptive transmission reset: The transmission may shift roughly for a few days as it relearns driving habits.
- Security system reactivation: Some vehicles require a relearn procedure for the immobilizer or key fob.
- Doesn’t fix the problem: If the issue isn’t resolved, the light will come back on.
Only use this method if you’ve already fixed the underlying problem and just need to reset the light.
Troubleshooting Common Issues
Even after resetting the light, you might run into problems. Here’s how to handle common scenarios:
The Light Comes Back On Immediately
If the check engine light returns right after you reset it, the issue wasn’t fixed. For example, a loose gas cap that you didn’t tighten properly will trigger the light again. Recheck your repair and ensure everything is secure.
The Light Returns After a Few Days
This suggests the problem is intermittent or not fully resolved. Use your OBD2 scanner to read the new codes. Compare them to the original ones—are they the same? If so, the repair may have been incomplete.
The Scanner Won’t Connect
If your OBD2 scanner won’t communicate with the Durango, check the following:
- Is the ignition in the “ON” position?
- Is the scanner compatible with OBD2 (all 1996+ vehicles are)?
- Is the OBD2 port damaged or dirty? Clean it gently with compressed air.
- Try a different scanner or have the port inspected by a mechanic.
The Light Is Flashing
A flashing check engine light indicates a severe misfire that can damage the catalytic converter. Pull over safely, turn off the engine, and call a tow truck. Do not drive the vehicle until it’s inspected.
When to See a Mechanic
While many check engine light issues can be handled at home, some require professional expertise. Seek a mechanic if:
- The light is flashing or stays on steadily after repairs.
- You’re unsure how to interpret the trouble codes.
- The problem involves the transmission, fuel system, or internal engine components.
- You don’t have the tools or confidence to perform the repair.
- The light keeps returning despite multiple resets.
A certified technician can perform a thorough diagnosis, run advanced tests, and ensure your Durango is safe and roadworthy.
Preventing Future Check Engine Light Issues
The best way to avoid dealing with the check engine light is to prevent it from coming on in the first place. Follow these maintenance tips:
- Check the gas cap regularly: Make sure it’s tight after every fill-up. Replace it if it’s cracked or worn.
- Follow the maintenance schedule: Refer to your owner’s manual for oil change intervals, spark plug replacement, and air filter changes.
- Use quality fuel: Stick to reputable gas stations to avoid contaminated fuel.
- Inspect belts and hoses: Look for cracks, leaks, or wear during routine checks.
- Keep the engine clean: A clean engine runs more efficiently and is easier to inspect.
Regular care not only prevents warning lights but also extends the life of your Durango.
