Engine coolant temp #2 showing -40F

[bobmbx]

Just noticed that OBDlink is showing the Engine Coolant Sensor 2 temp as -40F. Pretty sure thats not true. The #1 sensor shows 199F.

Is sensor 2 used on the Ecoboost?

Bobmbx: Short answer, Ignore it! A long answer will follow by tomorrow! I have the same numbers on my 2016. Sensor 1 is the one to fret over. I was clueless about sensor 2 and at first, I thought, Stupid Hillbilly that I am it was telling me the protection temperature of the coolant in sub-zero winter conditions. What it is actually in the governance of is most impressive ! And absolutely nothing any Expedition Owner needs to fret over. Anybody? Correct me if I am missing something!
