This sensor seems quite difficult to replace, as it looks like you would have to remove the PSU. The cable from this sensor runs up the back corner of the case and over the hard drive bay into the logic board. The air deflector is the clear plexi-plastic inner door - the sensor is located in the rear-most slot into which the rear 'foot' of the plexi door fits. if you have any luck with the things that you are trying please post back here. Check that inner door is secure and in place.' The inner door is indeed secure and in place and indeed the red LED does come on if the inner door is removed, proving that the sensor is working properly.Д®.f. Unfortunately about 10 minutes after starting the calibration it reports 'Error CPU0: CPU intake fan speed error. So I ran the Apple Service Diagnostic disk version 2.5.8 and it does indeed report that the CPUs require calibration. I read that the reason for this is that it needs a thermal recalibration.

So now I have swapped the logic board, resulting in the computer seeming working fine apart from the full fan speed. Then, all of a sudden, it failed to start up completely. This was never fixed because it happened only about once a month.

There's a bit of history here: I used this machine for a while and intermittently it would completely freeze and the fans would increase to full speed (presumably to prevent damage to the components). It runs fine, all temperatures look normal (in the 30-40 degree range), but all the fans are stuck on full. I am having the same problem with a dual 2GHz G5. A bad fan could result in a machine that overheats.ДЄlso if you had it in for service at an authorized provider tell them they didn't complete the repair correctly, or left something to slowly degrade if it was initially working fine. Then I would shop around the nearest service providers and see what they have to say about your test results.

If your machine is out of warranty, and is not under any return exchange program below: The hardware test CD that shipped with the machine though is called Apple Hardware Test, and its diagnostics are gospel, and indicate a hardware issue that need fixing.

If you got it from some unauthorized source, I'd not read much from it, since you don't know if it knows how to read your machine correctly as it may be a mismatched version # for the machine. рџџ The only thing I have not done is take out and reseat the CPU's, but as far as i can tell the only reason to do that is to force older versions of ASD to allow temperature calibration - but ASD v2.5.8 fixes that.ДЄpple Service Diagnostics? Are you talking about something other than Apple Hardware Test? If you have the official service diagnostics because you or a friend is an authorized service provider, I would send it in to Apple for service. What else can I try? I've spent about 40 hours on this so far. Is there another way to check that sensor? The inner door is indeed in place, and as far as I can tell the sensor is working since the indicator red LED on the logic board turns on and off when you remove the door. Check that inner door is secure and in place.' 'Error CPU0: CPU intake fan speed error. Check temperatures, all i think within normal range (<40 degrees (c), except GPU which is 65)ДЇinally I obtained the legendary Apple Service Diagnostic disc. Checked inner (clear plexi) door sensor I have tried the following well-known fixes, none of which has worked:

Now, nothing works - although if i manually put computer to sleep, the fans do turn off, and computer does wake up, which is nice. At first, resetting NVRAM from Open Firmware fixed the problem, but after a day or two it would start again. Now, the fans blow full speed all the time, from the moment of boot (before OS loads). Eventually resolved this with Apple Care by near-total hardware replacement: fan replacement, fan sensor replacement, case replacement, finally logic board replacement. About 1 year ago, had fan blowing after sleep problems (fans blow super hard, cannot wake from sleep).

I have a Power Mac G5 Dual 2.0Ghz, about 3 years old.
