Error in Diagnostics 4SNS/1/40000001:ID2S-0.000
Fans running loud on Imac 2011. Have run diagnostics and the following error appears:
Looks to be pointing to Direct current electrical sensor.
Any experts point me in the right direction please, I have swapped the PSU unit completely from a working Mac and this has not resolved the issue. PRAM and SMC resets have had no effect.
Using iStat Menu and I noticed there is no reading for:
Power Board Proximity
Power Primary heatsink
Power secondary heatsink
Looking to your experts for some assistance towards fixing this.
Update 25/01: I downloaded Temp Monitor App and noticed the following readings:
Maybe this helps pinpoint the problem. As far as I can see it points to power supply I have already swapped power supplies for known good power supplies from other macs.
