Need help with 2017 freightliner cascadia? temp sensor?

Temp sensor on my 16 is a little stud under the driver side mirror housing ,got an app so never messed with it .

 

Apu ..#### spell check

 

Saw a guy on another post said he tapes a handwarmer to the stud and problem solved .

 

Unplugging them won't keep it running if that is what your trying to do. An appropriate ohm resistor can fool it into thinking it is hot outside or as I use to do handwarmers a sock to insulate and a plastic bag taped over the mirror to keep the cooler air out. Could also get a 12v defroster and set that up on it

 

Bingo lol

 

That sensor is pretty is pretty sensitive tho as I held my fingers on it and the dash temp gauge immediately starting going up .

 

On past year model freightliner cascadia (maybe 2014?) , I was told once it's near the right frame rail up towards the very front of the truck below the radiator. I think the outside temp sensor you read on the dash, and the temp sensor used to control idle and other engine functions are two separate sensors. But I may be wrong. I'm just a truck driver after all.
