Why is my Ford Focus Check Engine Light On?

I have a 2015 Ford Focus and the check engine light has been on for a few days now. I'm not sure what could be causing it. Any advice on what I should do?

The check engine light could be on for a variety of reasons. It's best to take your car to a mechanic and have them run a diagnostic test to determine the exact cause. It could be something minor or it could be a more serious issue.

If your car is running fine and you notice the check engine light is on, it could be something as simple as needing a new gas cap. Check to make sure it's tightly secured and if that doesn't fix the issue, take it to a mechanic.

I had the same issue with my Ford Focus. The check engine light was on and it turned out to be a faulty oxygen sensor. It's best to get it checked out sooner rather than later to avoid any potential damage to your car.
