Why is the Ford Fiesta's engine light turning on after long drives?

I have a Ford Fiesta from 2012 and I noticed that after driving for a long time, the engine light turns on. What could be the reason for this? I regularly maintain my car and never had this issue before. Any advice would be greatly appreciated.

This could be a sign of a malfunction in the engine control system. I would suggest taking your car to a certified Ford mechanic for a diagnostic check and proper repair.

It could be a faulty oxygen sensor or a loose gas cap. Both are common issues in Ford Fiestas. I had the same problem and it was fixed by replacing the sensor.

I had a similar issue in my Ford Fiesta and it turned out to be a faulty catalytic converter. I would advise getting your car checked by a professional mechanic to avoid further damage.
