The temp guage in my overhead console always reads -40f. I know it can't be right- I'm in Texas and it's been 100+ for the last week. Is there a way to calibrate it, or does anybody know how to check the sensor/sending unit for it? Or even where the unit is located?
It's in a 2001 Ram 2500, Quad Cab 4x4

Thanks!

 

check to make sure its there .. and plugged in.. on your truck .. raise the hood.. its going to be on the hood itself.. around the latch area.. its kinda a funny looking cone shaped deal on a bracket..
