Before you reset the check engine light, it’s crucial to understand why it turned on in the first place. The light—often labeled “Check Engine,” “Service Engine Soon,” or with an engine icon—is part of your vehicle’s onboard diagnostic system (OBD2). It monitors engine performance, emissions, and other critical systems.
When a sensor detects a problem—like a misfire, faulty oxygen sensor, or loose gas cap—the system logs a trouble code and illuminates the light. Ignoring it can lead to reduced fuel efficiency, increased emissions, or even engine damage.
Common causes in the 2013 Durango include:
– Loose or damaged gas cap
– Faulty oxygen (O2) sensor
– Mass airflow (MAF) sensor issues
– Spark plug or ignition coil problems
– Catalytic converter inefficiency
– EVAP system leaks
Important: Never reset the light without first identifying and fixing the root cause. Resetting it prematurely is like turning off a fire alarm while the house is still burning—it doesn’t solve the problem.
Tools You’ll Need
To reset the check engine light on your 2013 Durango, you’ll need one or more of the following tools, depending on the method you choose:
- OBD2 Scanner: The most reliable tool for reading and clearing codes. Look for a basic code reader (around $20–$50) or a more advanced scanner with live data and code definitions.
- Owner’s Manual: Contains vehicle-specific instructions and fuse box diagrams.
- Basic Hand Tools: Screwdrivers, wrenches, or pliers may be needed to access the battery or fuse box.
- Pen and Paper or Smartphone: To record error codes before clearing them.
- Multimeter (optional): Useful for testing sensors or electrical connections if you’re diagnosing deeper issues.
Method 1: Using an OBD2 Scanner (Recommended)
The safest and most effective way to reset the check engine light is with an OBD2 scanner. This method ensures you’ve properly diagnosed the issue and clears the light without disrupting other vehicle systems.
Step 1: Locate the OBD2 Port
The OBD2 port in the 2013 Durango is typically located under the dashboard on the driver’s side. You’ll find it near the steering column, about knee-level. It’s a 16-pin connector, usually black or gray, and may be behind a small cover.
If you can’t find it, check behind the fuse panel or consult your owner’s manual. The port is standardized across all vehicles made after 1996, so it should be easy to identify.
Step 2: Turn Off the Ignition
Before plugging in the scanner, make sure the ignition is off. This prevents any electrical surges or communication errors between the scanner and the vehicle’s computer.
Step 3: Plug in the OBD2 Scanner
Insert the scanner’s connector into the OBD2 port. Make sure it’s fully seated and secure. Most scanners will power on automatically when connected.
Step 4: Turn the Ignition to “On” (Do Not Start the Engine)
Turn the key to the “ON” position. The dashboard lights should illuminate, but the engine should remain off. This allows the scanner to communicate with the vehicle’s computer.
Step 5: Read the Trouble Codes
Follow the scanner’s instructions to read the diagnostic trouble codes (DTCs). Most scanners will display codes like “P0420” or “P0171.” Write these down or take a photo—you’ll want to reference them later.
Use the scanner’s built-in code definitions or search online to understand what each code means. For example:
– P0420: Catalyst system efficiency below threshold
– P0171: System too lean (bank 1)
– P0300: Random/multiple cylinder misfire detected
Step 6: Fix the Underlying Issue
Once you’ve identified the problem, take steps to fix it. This might involve:
– Tightening or replacing the gas cap
– Replacing a faulty oxygen sensor
– Cleaning the MAF sensor with specialized cleaner
– Replacing spark plugs or ignition coils
– Repairing an EVAP leak
If you’re not comfortable performing repairs yourself, take the vehicle to a trusted mechanic. Be sure to provide them with the trouble codes for faster diagnosis.
Step 7: Clear the Codes
After the repair is complete, return to the scanner. Use the “Clear Codes” or “Erase DTCs” function to reset the check engine light. The scanner will send a signal to the vehicle’s computer to turn off the light.
Step 8: Turn Off the Ignition and Remove the Scanner
Once the codes are cleared, turn the ignition off and unplug the scanner. Start the engine to confirm the light is off.
Step 9: Complete a Drive Cycle (If Needed)
Some systems require a “drive cycle” to complete self-tests. This means driving under specific conditions (e.g., highway speeds, cold starts) so the computer can verify the repair.
For the 2013 Durango, a typical drive cycle includes:
– Cold start (engine off for at least 8 hours)
– Drive at 30–40 mph for 5 minutes
– Accelerate to 55 mph and cruise for 10 minutes
– Decelerate without braking
– Repeat 2–3 times
After completing the drive cycle, the computer should confirm no issues remain, and the light should stay off.
Method 2: Disconnecting the Battery (Manual Reset)
If you don’t have an OBD2 scanner, you can try resetting the check engine light by disconnecting the battery. This method forces the vehicle’s computer to reset, but it’s less reliable and may not work on all 2013 Durangos.
Warning: Disconnecting the battery can reset other systems, including radio presets, clock, and adaptive transmission settings. It may also trigger other warning lights temporarily.
Step 1: Turn Off the Engine and Remove the Key
Make sure the vehicle is completely off and the key is out of the ignition.
Step 2: Locate the Battery
The battery in the 2013 Durango is located in the engine compartment on the driver’s side. It’s housed in a plastic case with a positive (+) and negative (-) terminal.
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 battery terminal to prevent accidental contact.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer to fully discharge and reset. Some sources 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 the connection is tight to avoid electrical issues.
Step 6: Start the Engine
Turn the key to start the engine. The check engine light may flash briefly, then turn off. If it remains off after a few minutes of driving, the reset was successful.
Step 7: Reset Other Systems
You may need to reset the radio, clock, and power windows. Refer to your owner’s manual for instructions.
Method 3: Using the Gas Pedal Trick (Not Recommended)
Some online sources suggest a “gas pedal method” to reset the check engine light: pressing the accelerator three times in a row while the ignition is on. However, this method is not reliable for the 2013 Durango and may not work at all.
Modern vehicles like the Durango use sophisticated computer systems that don’t respond to such tricks. Additionally, this method doesn’t address the underlying issue, so the light will likely return.
We strongly recommend using an OBD2 scanner or battery disconnect instead.
Troubleshooting Common Issues
Even after resetting the check engine light, you might run into problems. Here’s how to handle common scenarios:
The Light Comes Back On After Reset
If the check engine light returns shortly after resetting, the original problem hasn’t been fixed. Recheck the trouble codes and inspect related components. For example:
– A P0420 code may indicate a failing catalytic converter
– A P0171 code could mean a vacuum leak or dirty MAF sensor
The Light Flashes While Driving
A flashing check engine light indicates a severe misfire that can damage the catalytic converter. Pull over safely, turn off the engine, and have the vehicle towed to a repair shop.
Other Warning Lights Appear
Disconnecting the battery can trigger lights like “Service 4WD” or “Traction Control Off.” These usually reset after a few drive cycles. If they persist, use an OBD2 scanner to check for new codes.
Radio or Clock Resets
This is normal after a battery disconnect. Use your owner’s manual to restore settings.
Preventing Future Check Engine Lights
The best way to avoid resetting the check engine light is to prevent it from coming on in the first place. Follow these maintenance tips:
- Check the gas cap regularly: A loose or cracked cap is one of the most common causes. Tighten it until it clicks three times.
- Use quality fuel: Low-octane or contaminated fuel can cause engine knock and trigger sensors.
- Replace air filters: A dirty air filter restricts airflow and affects engine performance.
- Follow the maintenance schedule: Replace spark plugs, ignition coils, and oxygen sensors as recommended (typically every 60,000–100,000 miles).
- Listen for unusual sounds: Knocking, pinging, or rough idling can signal early problems.
- Use a fuel system cleaner: Add a quality cleaner every 3,000–5,000 miles to keep injectors and sensors clean.
When to See a Mechanic
While many check engine light issues can be resolved at home, some problems require professional attention. See a mechanic if:
– The light is flashing
– You’re unable to read or interpret codes
– The repair involves complex components (e.g., catalytic converter, transmission)
– The light returns repeatedly after reset
A certified technician has advanced tools and experience to diagnose and fix stubborn issues.
