Why is my Ford Focus dashboard showing an engine warning light?

I've recently noticed that the engine warning light has turned on while driving my Ford Focus. What could be causing this issue and how can I fix it?

Rachel, this warning light could indicate a potential problem with your car's engine. It's important to have this checked by a mechanic as soon as possible to prevent any further damage to your car.

Rachel, this warning light could be caused by something as simple as a loose gas cap. Try tightening it and see if the light goes off. If not, it's best to have a professional diagnose the issue.

Rachel, I had the same issue with my Ford Focus and it turned out to be a faulty oxygen sensor. It's a quick and relatively inexpensive fix, so it's worth having it checked by a mechanic.
