How do I troubleshoot a check engine light on my Kia Sportage?

I recently bought a used Kia Sportage and the check engine light keeps coming on. What could be causing this issue and how can I resolve it?

The check engine light is a warning indicator that could be triggered by a variety of issues. The first step is to have the vehicle's computer scanned for trouble codes. This will help pinpoint the specific problem.

One common cause of a check engine light in a Kia Sportage is a faulty oxygen sensor. This can affect the vehicle's fuel economy and emissions. It's important to have this issue fixed promptly.

Another potential cause could be a loose gas cap. This may seem like a minor issue, but it can disrupt the fuel tank's vapor pressure and trigger the check engine light. Make sure the gas cap is properly secured.

If the check engine light is flashing, it's indicating a more serious problem that requires immediate attention. It's best to get the vehicle inspected by a mechanic as soon as possible to prevent any further damage.
