Why is my check engine light on in my Ford Fiesta?

I recently purchased a used Ford Fiesta and the check engine light keeps coming on. I'm not sure what the problem could be. Can anyone offer some advice?

It's possible that the issue is related to the emissions control system. It's important to take your car to a mechanic who specializes in Ford vehicles for a proper diagnosis and repair.

I had a similar issue with my Fiesta and it turned out to be a faulty oxygen sensor. Get it checked out as soon as possible because ignoring it can lead to bigger and more expensive problems.

The check engine light can come on for a variety of reasons, ranging from a loose gas cap to a more serious engine issue. It's always best to get it checked out by a professional to ensure the safety of your vehicle.
