    it doesn't have AHT on it

    ...

    /System/Library/CoreServices/ doesn't have a ".diagnostics" folder in it.

     

    Those two are not the same. Apple Hardware Test has traditionally been on the disc but OUTSIDE the "normal" File System. It has traditionally loaded with a very primitive loader that has nothing to do with Mac OS X.

     

    The convention of also listing it in /System/Library/CoreServices/.diagnostics is fairly new, and is not a good way to tell whether the diagnostic is actually on the disc.

     

    counterexample: I have a MacBook Replacement OEM disc that contains 10.6.7. It has:

     

    disk3s1       31KB    Apple-partition_map

    disk3s2 637.8MB     Apple_Driver_ATAPI  ** that is HUGE!  regular EFI_Boot is 209.7MB

    Mac OS X Install DVD  7.9GB Mountable System/Installer

     

    It claims to have AHT on it as well.

     

    there is no /System/Library/CoreServices/.diagnostics on that DVD

    Either way it is definately not on the disk they sent.  I tried multiple times to run it on restart in addition to searching through the files on there.  The disk was immediatley suspect because it does not look like an OEM disk, but I did try it anyway.

    I ended up finding the Apple Service Diagnostics disks online for my system and ran that.

     

    The test fails during Sensor tests:

     

    Temp (TNOD) - (MacPro) IOH or (iMac or mac mini) MCP, Tdiode (test 1) - Sensor Reads Within Operating Range

    - Check to ensure that sensor reads within operating range.

    ERROR - Sensor is reading above the high limit

    - TEST FAILED -

    I have a 2006 macbook pro Core 2 Duo 2.16 GHZ and I have also run into this issue. I wouldn't even care if there was some third party way to run diagnostics on my hardware.

    2006 models shipped with diagnostics on the original DVD.

     

    Where is your original DVD?

    I'm facing the same problem, where did you find the Apple Service Diagnostics online?

    Try a search for "Apple Service Diagnostics Disc - intel mac"

    Call Apple and request part # SRF 2Z691-6593. (you will need your MP serial number)

     

    It is "named" (DVD Mac Pro Applications Install Non E.S).

     

    Insert the DVD, restart holding the "d" key.

     

    You will launch AHT version 3A153.

    Follow the instructions.

    For what it's worth.

     

    Apple part number SRF 2Z691-6550 ALSO contains AHT 3A153 for the Mac Pro 2009.
