A lit check engine light doesn’t necessarily mean there is an issue with your engine. However, this light is trying to warn you of some issue with your vehicle and engine. This light can indicate a wide range of problems, as it is just a signal from the engine’s computer to the dashboard, so it's best to consult with an experienced mechanic to discover the issue.
