I fixed it!
I tried measuring voltage across the sensor and found that it was 1.3V when the nozzle was in the mV. So I disconnected the power to my (also NEW) heated bed, and the temp worked fine!
So I then saw lots of surface solder splatter around the connector on the bed which was shorting the two middle pins. After cleaning that off, it worked.
So the sensor had been confused by the short, but not enough to throw any errors.

It got weirder!
So I plugged in a spare nozzle temp sensor into temp3 and it then read a temp correctly and all was good, it would even heat up ok.
But if the sensor was unplugged an error was flagged right away. So it must be something to do with the sensor, even though I can read the correct resistance from it. Maybe the machine reads the resistance in a different way than my multimeter?
