Ok -60C is impossible or is it? (in the voice of Homer)...re: polar vortex! Hahaha Sorry had to throw that it.....
This doesn't sound just a bad voltage, sound like an IC fail: SRAM; Signal processor; AD converter; even a bad sensor; or such like.
What I'm saying is yes I could look at it but I suspect its more than a basic issue. I'd probably have to spend quite a bit of time deciphering, reverse engineering, before I could identify the possible culprit. If its an IC with firmware then back to square 1.
The only thing I,m thinking is the sensor, Signal processor is bad or power to either .....but why the -60C? Which takes us back to the controller MCU with firmware. So in other-words I could look at it but I suspect it'll still needed to be forwarded to the OEM.
