Before you reset the engine light, it’s crucial to understand why it turned on in the first place. The “Check Engine” light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). It monitors engine performance, emissions, and other critical systems.
When a sensor detects a problem, the vehicle’s computer stores a diagnostic trouble code (DTC) and triggers the light. The issue could be as simple as a loose gas cap or as complex as a failing catalytic converter.
Common causes include:
- Loose, damaged, or missing gas cap
- Faulty oxygen (O2) sensor
- Misfiring engine
- Mass airflow (MAF) sensor issues
- Evaporative emissions system leak
- Catalytic converter problems
- Spark plug or ignition coil failure
Ignoring the light can lead to reduced fuel efficiency, increased emissions, and even engine damage. So, always diagnose the issue before resetting.
Tools You’ll Need
To reset the engine light on your 2014 Dodge Durango, you’ll need a few basic tools. Here’s what to gather:
- OBD2 scanner: This is the most reliable tool. It plugs into your vehicle’s OBD2 port and reads error codes. Many affordable models are available online or at auto parts stores.
- Owner’s manual: Check your Durango’s manual for specific instructions and safety tips.
- Flashlight: Helps you see the OBD2 port and under-hood components.
- Gloves and safety glasses: Optional but recommended for safety.
- Wrench or socket set: Only needed if you plan to disconnect the battery.
If you don’t own an OBD2 scanner, consider borrowing one from an auto parts store (many offer free code reading) or purchasing a basic model for under $30.
Step-by-Step: Reset Engine Light Using an OBD2 Scanner
Using an OBD2 scanner is the most accurate and recommended way to reset the engine light on your 2014 Dodge Durango. Here’s how to do it safely and effectively.
Step 1: Locate the OBD2 Port
The OBD2 port is a 16-pin connector usually found under the dashboard on the driver’s side. In the 2014 Durango, it’s typically located below the steering wheel, near the fuse panel.
To find it:
- Sit in the driver’s seat and look down near your knees.
- You may need to crouch or use a flashlight to spot it.
- The port is rectangular and may have a small cover.
If you can’t find it, consult your owner’s manual or search online for “2014 Dodge Durango OBD2 port location.”
Step 2: Turn Off the Engine
Before connecting the scanner, make sure the engine is completely off. This prevents electrical issues and ensures accurate readings.
Step 3: Plug in the OBD2 Scanner
Insert the scanner’s plug into the OBD2 port. It should fit snugly—don’t force it. Most scanners have a keyed design, so it only fits one way.
Step 4: Turn the Ignition to “On”
Turn the key to the “ON” position (without starting the engine). This powers up the vehicle’s computer and allows the scanner to communicate with it.
You’ll see the scanner’s screen light up. Some models may display “Searching…” or “Connecting…” while it establishes a link.
Step 5: Read the Error Codes
Once connected, follow the scanner’s instructions to read the diagnostic trouble codes (DTCs). Most scanners have a “Read Codes” or “Scan” button.
The scanner will display one or more codes, such as P0455 (large evaporative leak) or P0302 (cylinder 2 misfire). Write these down—they’re essential for diagnosing the problem.
Step 6: Diagnose the Problem
Use the scanner’s built-in code definitions or search online for “2014 Dodge Durango [code] meaning.” For example:
- P0420 = Catalyst system efficiency below threshold
- P0171 = System too lean (bank 1)
- P0442 = Small evaporative leak
If the code points to a simple fix—like a loose gas cap—address it first. Tighten the cap or replace it if damaged.
For more complex issues, consider consulting a mechanic or using repair guides.
Step 7: Clear the Codes
After fixing the issue, return to the scanner and select “Clear Codes” or “Erase DTCs.” Confirm the action when prompted.
The scanner will send a command to the vehicle’s computer to reset the engine light. You should see a message like “Codes cleared” or “Reset successful.”
Step 8: Turn Off the Ignition and Remove the Scanner
Turn the key back to “OFF” and unplug the scanner. Store it safely for future use.
Step 9: Start the Engine
Start your Durango. The engine light should be off. If it’s still on, the problem may not be fully resolved, or the vehicle needs a drive cycle to complete its self-check.
Manual Reset: Disconnecting the Battery
If you don’t have an OBD2 scanner, you can try resetting the engine light by disconnecting the battery. This method forces the vehicle’s computer to reset, but it’s not always reliable and may not clear all codes.
Step 1: Turn Off the Engine and Remove the Key
Make sure the vehicle is off and the key is out of the ignition.
Step 2: Locate the Battery
Open the hood and find the battery. In the 2014 Durango, it’s usually on the driver’s side, near the front of the engine bay.
Step 3: Disconnect the Negative Terminal
Use a wrench or socket to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery.
Warning: Never disconnect the positive terminal first. Always start with the negative to avoid short circuits.
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 experts recommend up to 30 minutes for older systems.
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 Engine
Turn the key and start the Durango. The engine light may be off, but this isn’t guaranteed. Some codes require a drive cycle to clear.
Step 7: Check for Other Reset Issues
Disconnecting the battery can reset other systems, such as:
- Radio presets
- Power window settings
- Climate control memory
- Clock and trip odometer
You may need to reprogram these features.
Alternative: Drive Cycle Reset
Sometimes, the engine light will turn off on its own after the problem is fixed and the vehicle completes a “drive cycle.” A drive cycle is a specific sequence of driving conditions that allows the onboard computer to recheck all systems.
For the 2014 Durango, a typical drive cycle includes:
- Cold start (engine off for at least 8 hours)
- Idle for 2–3 minutes
- Drive at 30–40 mph for 5 minutes
- Accelerate to 55 mph and cruise for 10 minutes
- Decelerate without braking (coast)
- Repeat 2–3 times
After completing the drive cycle, the computer may clear the light if no issues are detected. This method works best for minor problems like a loose gas cap.
Troubleshooting Common Issues
Even after resetting, the engine light may come back. Here’s how to troubleshoot:
Light Comes Back On Immediately
If the light returns right after resetting, the problem wasn’t fixed. Recheck the error code and inspect the related component. For example, if the code was P0455, inspect the gas cap, fuel filler neck, and EVAP system.
Light Returns After a Few Days
This suggests an intermittent issue. It could be a failing sensor or a loose connection. Use the OBD2 scanner to check for pending codes (codes that haven’t triggered the light yet).
Scanner Won’t Connect
Make sure the ignition is on, the scanner is compatible with OBD2, and the port isn’t damaged. Try a different scanner if possible.
Battery Reset Didn’t Work
Some codes, especially those related to emissions, require a drive cycle or professional reset. Manual battery disconnect may not clear all stored data.
Other Warning Lights Appear
If the ABS, traction control, or airbag light comes on after a reset, the battery disconnect may have affected other systems. Drive the vehicle for a few miles to allow the computer to relearn settings.
Preventing Future Engine Light Issues
The best way to avoid engine light problems is through regular maintenance. Here are some tips:
- Check the gas cap: Always tighten it until it clicks 3–4 times after refueling.
- Use quality fuel: Stick to reputable gas stations to avoid contaminants.
- Replace spark plugs on schedule: The 2014 Durango typically needs new plugs every 100,000 miles.
- Clean the MAF sensor: Use a specialized cleaner every 30,000 miles.
- Inspect hoses and belts: Look for cracks, leaks, or wear during oil changes.
- Get regular tune-ups: Follow the maintenance schedule in your owner’s manual.
Prevention is always cheaper and easier than repair.
When to See a Mechanic
While many engine light issues can be resolved at home, some require professional help. See a mechanic if:
- The light is flashing (indicates a severe misfire that can damage the catalytic converter)
- You’re unsure how to interpret the error code
- The problem involves the transmission, engine internals, or emissions system
- The light keeps coming back after multiple resets
