Reset Service Engine Soon Light on Mitsubishi Outlander

In this article, we will guide you through the process of resetting the service engine soon light on your Mitsubishi Outlander. The service engine soon light, also known as the check engine light, is an important indicator that alerts you to potential issues with your vehicle’s engine or emissions system. While it may be alarming to see the light come on, it doesn’t always mean there’s a major problem. In many cases, it can be triggered by minor issues that can be resolved with a simple reset.

Why Does the Service Engine Soon Light Come On?

Before we dive into the steps to reset the service engine soon light, let’s briefly discuss why it might come on in the first place. The service engine soon light is connected to your vehicle’s onboard diagnostics system (OBD-II), which monitors various components and systems for any abnormalities. When the OBD-II system detects a potential issue, it triggers the service engine soon light to alert you.

The reasons for the light coming on can vary, ranging from a loose gas cap to a faulty sensor or more significant engine problems. It’s essential to address the issue promptly to prevent potential damage to your vehicle.

Step-by-Step Guide to Resetting the Service Engine Soon Light

Step 1: Check the Gas Cap

A loose or damaged gas cap can sometimes trigger the service engine soon light. Start by checking if the gas cap is securely tightened. If you find any damage or cracks, consider replacing it with a new one. After tightening or replacing the gas cap, the light may reset on its own after a few driving cycles.

Step 2: Check for Faulty Sensors

If the gas cap is not the culprit, the next step is to check for any faulty sensors. The most common sensors that can trigger the service engine soon light are the crankshaft position sensor and the camshaft position sensor. If your OBD-II scanner indicates these sensors as the problem, you may need to replace them to resolve the issue.

Step 3: Use an OBD-II Scanner

To reset the service engine soon light, you will need an OBD-II scanner. These scanners can be easily purchased online or borrowed from an auto parts store. Plug the OBD-II scanner into the diagnostic port, usually located under the dashboard on the driver’s side.

Step 4: Read and Clear the Codes

Once the OBD-II scanner is connected, follow the on-screen instructions to read the error codes. The scanner will display the specific codes that triggered the service engine soon light. Take note of the codes for further reference.

Next, select the option to clear the codes. The scanner will reset the light, and the codes should disappear. However, keep in mind that if the underlying issue is not resolved, the light may come back on after a few driving cycles.

Step 5: Address Any Underlying Issues

After clearing the codes, it’s crucial to address any underlying issues that caused the service engine soon light to come on. If the light returns after resetting, it’s a sign that there’s still a problem that needs to be fixed. In such cases, it’s best to take your Mitsubishi Outlander to a qualified mechanic or dealership for further diagnosis and repairs.


Resetting the service engine soon light on your Mitsubishi Outlander is a straightforward process that can be done with an OBD-II scanner. However, it’s essential to remember that the light is a warning sign and not something to be ignored. Always address the underlying issues to ensure the proper functioning of your vehicle and avoid potential long-term damage.

FAQs (Frequently Asked Questions)

It’s a good practice to perform a visual inspection of your vehicle regularly, checking for any warning lights, including the service engine soon light. If the light comes on, address it promptly to prevent any further problems.

While the service engine soon light may not indicate an immediate emergency, it’s essential not to ignore it. Continued driving with the light on can lead to more severe issues and potentially costly repairs.

Disconnecting the battery may reset the light, but it’s not a recommended method, as it will also erase other vital vehicle settings and data.

Some smartphone apps claim to offer OBD-II scanning and code clearing capabilities. While they may work for basic diagnostics, it’s advisable to use a dedicated OBD-II scanner for more accurate results and professional diagnosis.

If the codes are successfully cleared, and the light is off, you can continue driving your Mitsubishi Outlander. However, if the light comes back on, address the underlying issue promptly to ensure the vehicle’s safety and performance.
