Hardware Diagnostic Failure Code 4SNS/1/40000001:YH1R-0.000
What is this sensor? Temperature sensor right?
I’ve been using this iMac on and off a little bit and also reinstalled High Sierra 2-3 times and Mojave once without any issues or freezes.
Also ran a bunch of hardware diagnostics and that error popped up twice out of 10 or so. iStat Menus currently reports proper CPU temps, low to mid 30’s and ~60 under stress.
Several days ago it reported 100-130 though. I’m not complaining if the problem has disappeared … :)
To ensure there aren’t any significant problems caused by sensor failure what can I do that I haven’t already done? Or, is anything even necessary?
Thanks for the help.
