It most likely means you have a bad O2 (oxygen) sensor, to be completely sure, I would take it somewhere and have an OBD2 scan done on it. Hope this was some help.

Can a check engine light indicate a bad thermostat?
Many vehicles will trigger a check engine code if the engine never reaches its designated operating temperature (Such as if a thermostat was stuck open). However, there are hundreds of other reasons a check engine light can come on. Putting in a thermostat solely because the check engine light came on is a very bad idea. Any time that light comes on you should have the vehicle scanned by a trained proffessional (The guy at Napa doesn't count). A good service technician can use the information given by the engine computer to determine what is wrong with the vehicle.
