How to Reset Check Engine Light Dodge Durango

Seeing the check engine light illuminate on your Dodge Durango can be a cause for concern. It can indicate a potential issue with your vehicle’s engine or emissions system. However, sometimes the check engine light can be triggered by a minor issue or a temporary glitch. In such cases, you may be able to reset the check engine light yourself without visiting a mechanic. Here’s a step-by-step guide on how to reset the check engine light on your Dodge Durango.

Step 1: Check for a Loose Gas Cap

Before proceeding with resetting the check engine light, it is essential to check whether your gas cap is properly tightened. A loose or missing gas cap can trigger the check engine light. So, make sure to inspect the gas cap and tighten it securely. If the cap is damaged or missing, consider replacing it before resetting the light.

Step 2: Identify the OBD-II Port

The next step is to locate the OBD-II (On-Board Diagnostic) port in your Dodge Durango. This port is usually located under the dashboard on the driver’s side. It may be covered by a plastic cover, which you need to remove to access the port.

Step 3: Connect an OBD-II Scanner

Once you have found the OBD-II port, you need to connect an OBD-II scanner. This device allows you to interact with your vehicle’s onboard computer system and retrieve diagnostic trouble codes (DTCs). You can either purchase an OBD-II scanner or borrow one from a local auto parts store.

Step 4: Retrieve and Note Down the Trouble Codes

After connecting your OBD-II scanner to the port, you need to follow the instructions provided with the scanner to retrieve the trouble codes. These codes will give you an indication of the specific issue triggering the check engine light. It’s important to write down the trouble codes as you will need them later in the process.

Step 5: Fix the Underlying Issue

Resetting the check engine light without addressing the underlying issue is not a recommended solution. Once you have retrieved the trouble codes, it’s essential to diagnose and fix the problem that caused the light to illuminate. If you are not familiar with vehicle repairs, consider consulting a professional mechanic to diagnose and resolve the issue.

Step 6: Check Vehicle Readiness Monitors

Before resetting the check engine light, you should check the readiness status of your vehicle’s monitors. The OBD-II system performs various tests on different components of your vehicle to ensure they are functioning correctly. To reset the check engine light successfully, all the readiness monitors should be in a ready state. Consult your vehicle’s owner’s manual or an OBD-II scanner to check the readiness status of the monitors.

Step 7: Clear the Check Engine Light

Once you have fixed the underlying issue and ensured that the readiness monitors are ready, you can proceed with resetting the check engine light. Using your OBD-II scanner, navigate to the option to clear the codes. Select this option, and the scanner will send a command to your vehicle’s computer to clear the trouble codes and reset the check engine light. Wait for a few moments for the process to complete.

Step 8: Start the Vehicle

After clearing the codes, you should start your Dodge Durango to verify if the check engine light stays off. If the underlying issue has been resolved successfully, the check engine light should not re-illuminate. However, if the light comes back on, it indicates that the problem still persists, and further diagnosis and repairs may be necessary.
