Why is the check engine light on in my Ford Mondeo?

My Ford Mondeo has the check engine light on, and I'm not sure what to do about it. Can anyone offer advice on what could be causing this issue and how to fix it?

It's important to get your car checked out as soon as possible when the check engine light comes on. The issue could be something minor or something more serious. Have the diagnostic codes checked to determine the cause.
