How do I troubleshoot my Kia Rio's check engine light?

Whenever I drive my Kia Rio, the check engine light comes on. I've tried resetting it but it just keeps coming back. What could be causing this and how can I fix it?

It's important to get the check engine light diagnosed as soon as possible as it could indicate a serious problem with your car. I would recommend taking it to a mechanic or using a diagnostic tool to check the error code and pinpoint the issue.

If your check engine light turns on intermittently, it could be caused by a loose gas cap. Make sure to tighten it properly and see if the light goes off. If it persists, then it could be a different issue that needs to be addressed.

One common cause of a check engine light is a faulty oxygen sensor. This part helps regulate the air and fuel mixture in your engine and a malfunctioning sensor can cause the light to turn on. It's important to replace it to avoid potential engine damage.
