Excursion Automatic Temperature Control Issue

Interesting. I had something similar with my Excursion. Is the temp reading way off, or just jumping around? Could be the sensor itself?

The temperature reading is totally off, and the HVAC doesn't even seem to notice it. What exactly happened with yours? What symptoms did you see, and which sensor threw the code?

Yeah, that's almost exactly what I saw. I messed with it a bit, but ended up taking it to a shop. They figured it out quick. I'd suggest doing the same!

Just wanted to let you know the shop confirmed it. Replaced the sensor and a corroded connector. Cost me 95€. Appreciate the help!
