How to fix a Kia ProCeed's persistent engine light?

My Kia ProCeed's engine light keeps coming on, even after I have taken it to a mechanic and they couldn't find any issues. What could be causing this and how can I fix it?

It is possible that there is an issue with the car's sensors that is causing the engine light to come on. I would recommend taking it to a Kia dealership to have them run a diagnostic check on the car's computer to see if any error codes are being generated. They will be able to pinpoint the exact issue and provide a proper solution.

Another possible cause of the engine light could be a loose gas cap. Make sure to check that the cap is tightly secured and see if the light comes back on. If it does, then there may be a more serious issue that requires a mechanic's attention.

In some cases, the engine light can come on due to a faulty oxygen sensor. This can affect the car's fuel efficiency and performance. If the mechanic did not check the oxygen sensor during the diagnostic, I would recommend having it tested as well.
