Why is my Kia Rio displaying a check engine light?

I recently bought a used Kia Rio and the check engine light has been consistently coming on. What could be causing this and how can I fix it?

The check engine light can be triggered by a variety of issues such as a malfunctioning sensor or a loose gas cap. It is important to get the car diagnosed by a professional mechanic to identify the specific issue and prevent potential damage to the engine.

Make sure to check your Kia Rio's gas cap. Sometimes a loose gas cap can cause the check engine light to come on. If that's the case, simply tightening the gas cap or replacing a faulty one should solve the issue.

There are also potential emission control problems that can trigger the check engine light. It is always best to consult a mechanic for a proper diagnosis and solution.
