The light is on because the ECU had detected a problem with the emissions system. Once you have the problem fixed the light will go off. Have the ECU scanned and this will tell you the trouble code that has been set. This code will tell you what part is being effected, but not necessarily the defective part. Unless you are knowledgable you should seek professional help.
