    They say ignorance is bliss, before you messed with your tps sensor were you concerned about the heat . If the bad sensor was not melted or deformed I'm sure the heat is nothing unusual.

    Yeah, not deformed. Still a little too hot to be placed there though. Would replace every year just to be safe. Need to take voltage readings while engine is worked up nice and hot and with the throttle moving, they probably start to go out of spec within a year after new, its just a slow decline. But you always want the TPS to be working 100%, and not 90% or 80%. Your transmission uses it to determine how much pressure to give.

    Even after replacing the throttle body gasket at the time I did the sensor, I can still feel the throttle body become burning hot to the touch.

    I'm thinking of also placing a thin gasket (same thickness as the TB gasket) directly under the sensor itself. This should alleviate much of the heat going to the sensor. And I don't think having a gasket just a few mm thick placed under the sensor will affect anything.
