Like the title says. Today i went out to start the car, it was -9 degrees F out. According to my Aeroforce my IAT temp is 65,xxx. Is this a sign of IAT failure?

I found out rockauto has them for 14 dollars so i got a new one along with a new AC Delco O2 sensor and a gasket for my EGR valve. In the meantime i went back out and turned the key, IAT was back down to 37* which in the garage was much more accurate. In the meantime I moved my IAT sensor back up to the coupling between the TB and my FWI since in winter time my IAT sees much lower temps anyways.

Sounds like a loose connection and an open somewhere. Could have been the connector itself?
Its not common to have to replace the IAT sensor.

What does IAT stand for?

Intake Air Tempreture

How old is the scangauge? My guess is that its a bug in the scangauge reading neg temps.

hmmm, not sure. I bought it from you guys and according to my log i installed it 11/15/06. That is quite possible as it was -9 and my IAT sensor was right next to my filter down in the fenderwell. I checked the connections on the caspers extension harness to the sensor and to the factory wiring and it was all connected and the connections were clean.
