How do I solve a check engine light on my Ford Focus?

I have a 2015 Ford Focus and the check engine light recently came on. I have noticed a decrease in performance and don't know where to start in fixing this issue. Any advice?

First, check your gas cap to make sure it is screwed on tightly. This can often generate a check engine light. If that doesn't solve the issue, take your car to a mechanic to run a diagnostic test. They will be able to pinpoint the exact issue and give you a recommended solution. Good luck!

I had this same issue with my Ford Focus and it ended up being a faulty oxygen sensor. This is a common issue with Ford vehicles and can easily be replaced. Before going to a mechanic, you can try replacing the oxygen sensor yourself. It's a simple fix and will save you money.
