Check your gas cap to make sure it seals tight. My check engine light comes on every now and then in my 1991 Camry and once I reseat the cap it goes out almost immediately. If this is not the problem have a mechanic check the oxygen sensor. Good luck, JFD EGR Va.ve? It might be your EGR valve which is part of your emissions system. My 1997 Celica passed the emissions test but the EGR valve still needed to be replaced. After it was replaced, the check engine light went off. The part cost about $75 from a Toyota dealer.
