well i have replaced the iat sensor twice this year cause the bulb inside was broken and the cel is back on for the same thing i am lonly running 9 lb boost. i recenly cranked it to about 11 but not enough fuel so put it back to 9. i havent taken the sensor out yet to check the bulb but im sure that it is broken again. it is saying high circuit input. am i doing something wrong or am i just having bad luck with these. any help would be great thanks

Try getting a REAL OEM unit from the dealer. The "OE" units at vatozone are from some aftermarket manufacturer that copied the OEM unit.

i had the same exactly problem with my 96 turbo'd gs and i kept throwing IAT sensor codes... i replaced it and for a while it kept coming back till i went to autozone and had them delete all my CEL's and then i never had that code come back... but simply taking the neg battery off didnt erase the code so maybe try that??? please let us know if you find anything out...
