Climate Control DTC?

I have a '06 F250 with auto climate control. It never shows the correct outside temp, most the time it shows -40. The AC works occasionally, but only when set to 60°, anything higher and no AC. Also, when not using AC it blows the same temp from 65°-90°. When running the DTC on the unit, it flashed 55 & 12°E.

Any suggestions?

I am by no means an expert but when I was replacing my intake air temp sensor they kept trying to give me the ambient air temp sensor. Reading a -40 all the time I would guess its failed and would start with that. As crazy has the HVAC systems are now days I would think the truck is shutting the A/C down thinking its -40 out. Just a guess.
