Hi,
This means that the engine computer has detected some kind of problem with the engine control systems or perhaps the emission systems.
In order to find out what was detected, you would need a code reader to find out what Diagnostic Test Code (DTC) is stored in the computer. Most code readers come with a book that will help decode the DTC. Once you know the code, you will know what system or systems to look at that could be causing the light. It will still have to be diagnosed, but it will point you in the right direction.
I have included a link to a list of some of the codes that you may see.
What else can I help you with?
