Why is my Ford Galaxy's check engine light on?

I've noticed that my check engine light on my Ford Galaxy has been on for a few days now. I'm worried it might be a major issue. Should I take it to the mechanic or can I fix it myself at home?

It's always best to take any car issues to a mechanic to get a proper diagnosis. They have the expertise and tools to accurately assess and fix the problem. Don't wait too long, as it could potentially lead to bigger and more expensive issues.

You can try checking your gas cap first, as a loose or faulty cap can sometimes trigger the check engine light. If that doesn't solve the issue, then it's best to take it to a professional.
