Why is the Ford S-Max's engine light on and how can I fix it?

I have a 2015 Ford S-Max and recently the engine light has been turning on and off. It's been causing some concern, so I wanted to know what could be causing this and how I can fix it.

One possible reason for your engine light turning on and off could be a faulty oxygen sensor. I recommend getting this checked and replaced by a certified mechanic as soon as possible.

Another reason could be a loose gas cap. Try tightening the gas cap and see if the light turns off. If not, then it's best to take your car to a mechanic for further inspection.

It could also be a problem with the catalytic converter. This is a crucial component of your car's emission control system. It's best to get this checked and replaced if necessary by a professional.
