Temp warning but no overheating

[ainarssems]

It's a bit of weird one, considering there is a voltage reading between both contacts at the plug means they are both connected to something so I would be more inclined to think one of them could be shorting to something else rather than break in wire. Could be loose connection, sometimes connected like when you measured but coming loose at times. I guess I would first try to rule out problem in dash by shorting the wires by the dash. I had brake pad warning light coming on my ROP S8, It was a break in cable somewhere but I just connected wires behind dash to get rid of warning.
