Why is my Kia Soul showing a check engine light?

I've recently noticed that my 2015 Kia Soul has a check engine light on. It seems to be running fine though. What could be causing this and how should I address it?

The check engine light can come on for a variety of reasons, but it's important not to ignore it. The best course of action is to have a mechanic run a diagnostic test to determine the exact cause.

One common cause of a check engine light is a loose or faulty gas cap. Try tightening it or replacing it to see if that resolves the issue.

Another possibility is an issue with the oxygen sensor. This can affect your fuel economy and emissions so it's important to have it checked and replaced if necessary.
