Temp sensors

[Statcher1]

Anybody ever noticed there intake temp sensor reading this low. I noticed on my Bullydog gauge this morning that the intake was reading 0*F while I was driving. The outside temp was around 12*F. The intake never budged from zero until I let the truck set and idle for about an hour while I was thawing out some air brakes. I was curious if any of you guys have noticed what the cutoff temp is for the intake sensor to read is.

Not sure about the IAT temp but I know when I cold start my truck the OIL and ENGINE temps read 100*F (it was 21*F out today) when i know the motor is dead cold. After a min it will start going up when the engine and oil temps go above the set low value.

Im sure that the IAT also has that as well. But if the motor was full warm there is no way its reading 0*F even if the outside temp is 12*F. I would restart the motor or tuner and check again…. or perhaps check the connector on the intake tube.
