Why is the Ford Focus' Check Engine Light On?

I have a 2018 Ford Focus and I noticed that the check engine light turned on. I'm not sure what could be causing it, but I want to make sure it's nothing serious. Can anyone give me some advice on what to do?

The check engine light can turn on for a variety of reasons, ranging from a loose gas cap to a more serious issue. I recommend taking your car to a trusted mechanic to get the code read and determine the cause of the light.

I had a similar issue with my Ford Focus and it turned out to be a faulty oxygen sensor. It's important to get it checked out and fixed as soon as possible to avoid any potential damage to your car.
