Question about an SGI Fuel issue / fuel sensors ( current - temp )

[Mazzini Alessandro]

Hello,

Since there are a lot of experts here ( I guess, at least ), I would like for an opinion / ideas / knowledge.

I've been told that the temperature sensors on Fuels are subject to get defective.
Is the same valid for current sensors ?

The question is due to this... I just got a Fuel donated to me, very kindly, that didn't turn on once I tried to. (the old owner didn't turn it on in a while, I was told)
I've connected to the L1 diagnostic serial port on the mb and ...
The env system prevents it from turning on for 2 reasons

1) XIO V12 bias with a value of 5.81 , considered too low
2) Odyssey temp fix at 93c at box turned off

But I managed to run env while the 30 seconds timer announcing the power down were running and... it shows that 12V and 12V IO are perfect with the psu "running" so... any idea if the xio v12 bias sensor is connected with the odyssey temp sensor and thus could be simply faulty.
I could do a test turning off env monitoring, but I would prefer to do it only after hearing opinions . given I don't know what kind of damages could happen if v12 bias is right , instead, and the system is brought up

Environmental monitoring is enabled and running.
