Why does my Ford Puma's Check Engine Light Keep Coming On?

I have a Ford Puma and recently the Check Engine light has been coming on. I took it to a mechanic and they said the issue was related to the coolant system. They fixed it but now a few days later the light is back on. I've checked the coolant levels and they are fine. What could be causing this issue?

It sounds like there may be an underlying issue in your coolant system that is causing the Check Engine light to come on again. It's important to get this looked at by a mechanic as soon as possible to avoid any potential damages to your car.

Sometimes the Check Engine light can come on due to a loose gas cap. Make sure it's screwed on tightly and see if that helps. If not, it may be a sensor issue and you should have it checked by a mechanic.
