Temp reading is wrong?

So my 3.1 printer committed suicide the other day and I came hone to the glob of Death. My extruder could not be saved so I decided to take the opportunity to upgrade to the BETA2 tool head. Now that I'm finished putting it together, I finally fired up the printer and Klipper and my extruder temp is reading 158° despite having not even tried to heat up my hot end. Before noticing this, I tried to heat it up and got a shutdown due to "extruder not heating at expected rate." But my hot end is cold to the touch, yet still reads this high temp. Any idea what I did wrong?

sensor_type: pt1000 But first, post your printer.cfg and confirm what hotend you've got

Not sure what you meant when you said "sensor_type: pt1000" as I am not a very tech savvy person. Had a lot of help setting this thing up to begin with. And how do I post the printer.cfg? I've double checked it and I did need to update my extruder but I'm still using the same rapido I've had. Lol how do you know? And then how would I know if it's the same issue?

by "post" i mean put your printer.cfg here as a file so others can review it

Would have been better to just post the file instead of a zip, but I got it

Alright, see towards the bottom there is a "USER OVERRIDES" section? And under that there is a [fan] section? Under that, put in
sensor_type: PT1000
sensor_type: PT1000

it told klipper what kind of temp sensor is on the hotend There are different kinds that report differetn number depending on the temp. That setting let s it know how to translate it
