How to troubleshoot a check engine light on a Kia Sorento?

My check engine light just came on in my Kia Sorento. What should I do to troubleshoot the issue? Is it something I can fix on my own?

First, make sure your gas cap is on tight. If it is loose, this can trigger the check engine light. If that doesn't solve the issue, you can take your Sorento to a local auto parts store and have them run a diagnostic test for free.

If the diagnostic test shows a specific error code, you can research it online to see if it's something you can fix on your own. If it's a more complicated issue, it's best to take your Sorento to a trusted mechanic.

In my experience, the most common cause of a check engine light on a Kia Sorento is a faulty oxygen sensor. If that's the case, it's best to have a professional replace it to ensure it's done correctly.
