PID tune not working

I have a RatRig Vcore 3 that I just updated to RatOS 2 from V1. It was a complete refresh and flash of the boards. Got everything up and running, but when I went to do a PID tune of the hot end, it failed. I immediately noticed two things. 1. It’s reading the Hotend as 160c, but it’s room temp. 2. When it starts the PID tune, the temp drops. I thought, oh it thinks a pin is reversed,… well that doesn’t make sense because they are not a polarity based pin such as a motor.. Anyone have any ideas??

You have the wrong thermistor, set it to a pt1000

I assume I need to add that to printer.cfg as ‘pt1000’ That did it, need to actually be ‘PT1000’ thank you @blacksmithforlife
