What causes the check engine light to turn on in my Kia Sorento?

I noticed that the check engine light came on in my Kia Sorento. I'm not sure what could be causing it. Can someone help me troubleshoot this issue?

The check engine light can turn on due to a variety of reasons, such as a loose gas cap, a faulty oxygen sensor, or a malfunctioning catalytic converter. It's best to take your Kia Sorento to a mechanic to get it properly diagnosed.

Before heading to a mechanic, make sure to check your gas cap first. A loose or faulty gas cap can often cause the check engine light to turn on. Tighten it or replace it if necessary.

Another common cause for the check engine light to turn on is a faulty oxygen sensor. This can cause a decrease in fuel efficiency and may also damage the catalytic converter if not addressed.
