Step-by-Step Guide: How to Reset the Check Engine Light on Your Subaru Vehicle

If you’re a Subaru owner, you may have experienced the frustration of seeing the check engine light appear on your dashboard. This warning light can indicate a variety of problems, from minor issues to serious mechanical failures. In this article, we’ll show you how to reset the check engine light on your Subaru vehicle, providing clear and concise instructions so you can get back on the road with peace of mind.

What Does the Check Engine Light Indicate?

The check engine light (CEL) is part of your car’s onboard diagnostic (OBD) system. This system monitors various components of your vehicle and alerts you to potential faults or malfunctions. When the CEL appears, it means that the OBD system has detected an issue with your car that needs attention.

Many factors can trigger the CEL, from a loose gas cap to a faulty oxygen sensor. Some of the most common causes include:

  • A malfunctioning sensor
  • A problem with the fuel system
  • Electrical issues
  • Emissions problems
  • Mechanical problems

Whatever the cause, it’s essential to address the issue promptly to avoid further damage to your vehicle.

Steps to Take to Reset the Check Engine Light

Resetting the CEL on your Subaru vehicle is a straightforward process, but it’s important to note that this action does not fix the underlying issue. It only clears the fault codes from your car’s OBD system. Therefore, we recommend that you identify and resolve the root cause of the problem before resetting the CEL.

Here are the steps to reset the check engine light on your Subaru vehicle:

Step 1: Turn off the engine
Make sure the engine is turned off and the key is removed from the ignition.

Step 2: Locate the OBD-II port
The OBD-II port is a small, rectangular connector located under the dashboard on the driver’s side of the vehicle. It’s typically near the interior fuse box.

Step 3: Plug in the OBD-II scanner
Connect the OBD-II scanner to the port. If you don’t have a scanner, you can borrow or purchase one from a local auto parts store or online.

Step 4: Turn on the scanner
Turn on the scanner and follow the manufacturer’s instructions to navigate to the "Clear Codes" function.

Step 5: Clear the codes
Select "Clear Codes" to reset the CEL. The scanner will communicate with your car’s OBD system and remove the fault codes.

Step 6: Turn off the scanner
Once the codes have been cleared, turn off the scanner and disconnect it from the OBD-II port.

Step 7: Start the engine
Start the engine and check to see if the CEL has been reset. If the light is still illuminated, there may be an ongoing issue that needs attention.

Additional Tips and Troubleshooting

If you’re unable to reset the CEL using the above steps or if the light continues to appear, here are some additional tips and troubleshooting measures to try:

  • Check the fuel cap: A loose or damaged fuel cap can cause the CEL to illuminate. Make sure the cap is tight and secure.
  • Drive the car: Sometimes, a simple drive can reset the OBD system and clear the fault codes.
  • Check the battery: A weak battery can cause electrical issues that may trigger the CEL. Make sure your car’s battery is charged and in good condition.
  • Consult a mechanic: If you’re unable to diagnose or fix the underlying issue, it’s best to take your car to a qualified mechanic for assistance.

Q: Is it safe to continue driving with the check engine light illuminated?
A: It depends on the cause of the issue. If the light is flashing, it indicates a severe problem that could damage your vehicle. In this case, we recommend turning off the engine and seeking immediate assistance. If the CEL is steady, it may indicate a minor issue, but it’s still best to diagnose and address the problem promptly.

Q: Will resetting the check engine light fix the underlying issue?
A: No, resetting the CEL only clears the fault codes from your car’s OBD system. It doesn’t address the root cause of the problem, so it’s essential to identify and resolve the issue before resetting the light.

Q: Do I need a specialized scanner to reset the check engine light on my Subaru?
A: No, you can use a standard OBD-II scanner to reset the CEL on your Subaru vehicle.

In conclusion, the check engine light can indicate a range of issues with your Subaru vehicle. While resetting the light is a simple process, it’s crucial to address the underlying issue to avoid further damage. Follow the steps outlined in this article, and if you’re unsure or unable to fix the problem, seek help from a qualified mechanic. With a little troubleshooting and maintenance, you can keep your car running smoothly and efficiently for years to come.
