Before you reset the light, it’s crucial to understand what triggered it. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your Durango’s onboard diagnostics system (OBD2). It illuminates when the vehicle’s computer detects a problem that could affect emissions, performance, or safety.
Common causes on the 2017 Dodge Durango include:
- Loose, damaged, or missing gas cap
- Faulty oxygen (O2) sensor
- Misfiring engine (spark plugs or ignition coils)
- Catalytic converter issues
- Mass airflow (MAF) sensor problems
- Evaporative emissions system leaks
- Exhaust gas recirculation (EGR) valve malfunction
Ignoring the root cause and simply resetting the light is like turning off a smoke alarm while the house is still on fire. The problem will likely return, and in some cases, it could lead to more serious damage or failed emissions tests.
That’s why step one is always diagnosis.
Step 1: Diagnose the Problem
You can’t fix what you don’t understand. Before attempting to reset the check engine light, you need to know why it came on.
Use an OBD2 Scanner
The most reliable way to diagnose the issue is with an OBD2 scanner. These devices plug into your Durango’s diagnostic port and read the trouble codes stored in the vehicle’s computer.
Here’s how to do it:
- Locate the OBD2 port. In the 2017 Dodge Durango, it’s usually under the dashboard on the driver’s side, near the steering column. It’s a 16-pin connector, often covered by a small panel.
- Turn the ignition to the “ON” position (but don’t start the engine).
- Plug in your OBD2 scanner. Most models will power on automatically.
- Follow the scanner’s prompts to read the trouble codes. Common codes for the Durango include P0457 (loose gas cap), P0133 (O2 sensor slow response), and P0300 (random misfire).
- Write down the codes and look them up using the scanner’s built-in database or an online resource like OBD-Codes.com.
If you don’t own a scanner, many auto parts stores like AutoZone, O’Reilly, or Advance Auto Parts offer free code reading. Just drive in and ask—they’ll plug in their scanner and tell you what’s wrong.
Check the Gas Cap
One of the most common—and easiest—fixes is the gas cap. A loose, cracked, or missing gas cap can cause a small leak in the evaporative emissions system, triggering the check engine light.
To check:
- Remove the gas cap and inspect it for cracks, wear, or a damaged seal.
- Reinstall it firmly until you hear it click 3–5 times.
- Drive the vehicle for a few days. If the light turns off on its own, the cap was the culprit.
If the cap looks damaged, replace it with an OEM (original equipment manufacturer) part. Aftermarket caps may not seal properly and can cause the light to return.
Step 2: Fix the Underlying Issue
Once you’ve identified the problem, it’s time to fix it. This step is non-negotiable. Resetting the light without repairing the issue is a temporary fix at best.
Common Repairs for the 2017 Durango
Depending on the trouble code, your repair may involve:
- Replacing the gas cap: Cost: $15–$40. Easy DIY job.
- Replacing spark plugs or ignition coils: Cost: $100–$300. Moderate difficulty.
- Cleaning or replacing the MAF sensor: Cost: $50–$200. Use MAF cleaner spray; avoid touching the delicate wires.
- Replacing an O2 sensor: Cost: $100–$300 per sensor. The Durango has multiple O2 sensors—front and rear.
- Repairing EVAP system leaks: May require smoke testing by a professional.
If you’re not comfortable performing these repairs, take your Durango to a trusted mechanic. Some issues, like catalytic converter failure, can be expensive and complex.
Step 3: Choose a Reset Method
After the repair is complete, you can reset the check engine light. There are several methods, each with pros and cons.
Method 1: Use an OBD2 Scanner (Recommended)
This is the safest and most effective way to reset the light.
Steps:
- Ensure the repair is complete and the ignition is off.
- Plug the OBD2 scanner into the diagnostic port.
- Turn the ignition to “ON” (engine off).
- Navigate the scanner menu to “Clear Codes” or “Erase DTCs.”
- Confirm the action. The scanner will send a signal to the vehicle’s computer to reset the check engine light.
- Turn off the ignition and unplug the scanner.
- Start the engine. The light should be off.
Tip: Some advanced scanners also allow you to view live data and monitor sensor performance, which can help confirm the repair was successful.
Method 2: Drive Cycle (Automatic Reset)
Modern vehicles like the 2017 Durango are designed to run self-tests during normal driving. If the issue is fixed, the computer may turn off the light automatically after completing a “drive cycle.”
A drive cycle is a specific sequence of driving conditions that allows the vehicle to test various systems.
For the Durango, a typical drive cycle includes:
- Start the engine when cold (overnight).
- Let it idle for 2–3 minutes.
- Drive at 30–40 mph for 5–10 minutes.
- Accelerate to 55–60 mph and maintain speed for 10–15 minutes.
- Decelerate without braking (coast) for 3–5 minutes.
- Repeat 2–3 times over several days.
After completing the drive cycle, the vehicle’s computer will re-run its emissions tests. If all systems pass, the check engine light should turn off.
Note: This method can take several days and may not work if the problem persists.
Method 3: Disconnect the Battery (Last Resort)
Disconnecting the battery can reset the vehicle’s computer and turn off the check engine light. However, this method has downsides and should only be used if other options aren’t available.
Steps:
- Turn off the engine and remove the key.
- Open the hood and locate the battery (passenger side).
- Use a wrench to loosen the negative (-) terminal clamp.
- Disconnect the negative cable and wait 15–30 minutes. This allows the vehicle’s capacitors to discharge and the computer to reset.
- Reconnect the negative cable and tighten securely.
- Start the engine. The check engine light should be off.
Warning: Disconnecting the battery can reset other systems, including:
- Radio presets and clock
- Power window and seat memory
- Adaptive transmission learning (may cause rough shifting initially)
- Anti-theft system (may require re-syncing)
Also, this method doesn’t guarantee the light will stay off if the underlying issue isn’t fixed.
Step 4: Verify the Reset
After resetting the light, you need to confirm it stays off.
Monitor the Dashboard
Start the engine and check the dashboard. The check engine light should be off. If it flashes or comes back on immediately, there’s still an active problem.
Drive and Observe
Drive your Durango for a few days under normal conditions. If the light returns, the issue wasn’t fully resolved. Recheck the trouble codes and consider professional diagnosis.
Use the OBD2 Scanner Again
Plug in your scanner to check for pending or stored codes. Even if the light is off, the scanner may show “pending” codes that could trigger the light later.
Troubleshooting Common Issues
Sometimes, resetting the check engine light doesn’t go as planned. Here’s how to handle common problems.
The Light Comes Back On
If the check engine light returns after a reset, it means the root cause wasn’t fixed. Possible reasons:
- The repair was incomplete or incorrect.
- A new issue has developed.
- The vehicle hasn’t completed its drive cycle yet.
Solution: Re-scan for codes and re-evaluate the repair. If you’re unsure, consult a mechanic.
The Scanner Won’t Clear Codes
Some scanners can’t clear codes if the vehicle is still detecting a problem. This is a safety feature.
Solution: Fix the issue first, then try clearing the codes again.
Battery Disconnect Didn’t Work
If disconnecting the battery didn’t reset the light, the problem may be:
- The issue is still present.
- The vehicle’s computer requires a specific reset procedure.
- The light is controlled by a separate system (e.g., transmission or ABS).
Solution: Use an OBD2 scanner or visit a dealership.
Radio or Settings Reset After Battery Disconnect
This is normal. To restore settings:
- Re-enter radio presets.
- Reset the clock.
- Re-sync power windows (if applicable).
Some Durangos may require a dealership tool to fully restore adaptive settings.
Preventing Future Check Engine Lights
An ounce of prevention is worth a pound of cure. Here’s how to avoid future check engine light issues on your 2017 Durango.
Regular Maintenance
Follow the manufacturer’s maintenance schedule. Key items include:
- Oil changes every 6,000–8,000 miles
- Spark plug replacement every 100,000 miles
- Air filter replacement every 15,000–30,000 miles

Inspect the Gas Cap Monthly
Make it a habit to check the gas cap during fuel stops. Ensure it’s tight and undamaged.
Avoid Short Trips
Frequent short trips don’t allow the engine to reach optimal temperature, which can prevent the OBD2 system from completing self-tests. Try to take longer drives occasionally.
Listen to Your Vehicle
Unusual noises, vibrations, or performance issues can be early signs of trouble. Address them before they trigger the check engine light.
When to See a Mechanic
While many check engine light issues can be resolved at home, some require professional help. Seek a mechanic if:
- The light is flashing (indicates a severe misfire that can damage the catalytic converter).
- You’re unable to diagnose or fix the problem.
- The repair involves complex systems like the transmission or emissions control.
- The light returns repeatedly after reset.
A certified technician has advanced tools and expertise to handle stubborn issues.
