RepairPal has a good guide to the check engine light--what might be causing it and what you should do: http://repairpal.com/check-engine-light
usually the light indicates something wrong with the emissions system (for example: a faulty oxogen sensor, or rarely a dead cat. converter)you can take your vehicle to an auto parts store they usually have a scan tool that they can hook up, it will give them a code and will tell you something like that. hope this helps
