Can a loose gas cap turn on my check engine light?

Yes it can. The check engine light can come on for many reasons, and when it’s on you should have it checked it could be something that will make your car stop running and get you stuck on the road. But yes it can be as simple as a loose gas cap, your car is equipped  with a system that stops fuel vapor from getting into the atmosphere this system pulls a vacuum on the fuel tank, when it can’t it turns the light on to let you know there’s a problem.
