corsa engine managment?

Get the fault codes read. That'll tell you why the engine management system is turning on the light. All you have to do is think through the possible causes.

Edit: Found this link (Which you should have found if YOU had done a search). It seems quite helpful, especially posts 11 and 12.

Unfortunately, I can't tell how relevant these suggestions are, as you have not told us the exact model/engine. This should give you enough to get a long way to having it sorted.
