The 'Check Engine' light could indicate a variety of issues, ranging from a loose gas cap to a more serious engine problem. It's best to take your car to a certified mechanic to diagnose the exact issue.

In the meantime, make sure to check your gas cap and tighten it if needed. Sometimes a loose gas cap can trigger the 'Check Engine' light.

If the light is flashing, that indicates a more serious issue and you should immediately take your car to a mechanic. Ignoring the 'Check Engine' light can lead to more expensive repairs in the future.
