  • tps sensor & air temp sensor

    hiya, in my seemingly endless quest to cure my boost/missfire problem where abouts are the tps and air temp sensor located and what readings would i get from a multimeter to tell me if there knackered. i have an idea of which ones which but i'd like to just double check first.
    cheers

    Air temp sensor is the little black one on top of the IM i believe? Am guessing the TPS is on the throttle body by the throttle cable somewhere.

    Dont know about any readings you should get but the info maybe on S2Central.net maybe?

      Yes - the graphs for IAT and CTS are on http://s2central.net - follow links to technical section and engine / motronic... The 3B area links to this data for now - its common to ABY of course.

          If your temp sensor is fooked, i have a new one from the dealer that i never fitted, still in its sealed bag.

                    cheers for the offer mate, but if audis2avant wants it sell it to him because apparently the garage say that neither of these are faulty.
