Looks like you found what I was about to tell you.  If the sensor works
but consistently reads 22C low, you can set (from the console) the
shutdown temperature to be 22C lower.  I don't remember how to do it, but
I did do that before on a DS10L. (pushed my luck on a system that would
overheat on hot summer days in an unairconditioned room by raising the
temp 2C.  I risked frying the CPU but hey, the system was free from
Islandco and was a hobbyist system so I wouldn't be out anything.  The CPU
survived my abuse)
