That info should be in the owner's manual I thought, or surely the dealer can help you if you bought it from one. I'd think they would even if you didn't by it from them. Come to think of it, it should be on a ownership card or like that came with the car from the dealer and is in the owner's manual case or similar type holder. Did you try doing a search in the Taurus forum? Try not to be too specific, but don't look up just "code" as you'll get a million hits for fault codes.
