How Can I Run Apple Hardware Test?

I'm having constant kernal panics and need to run AHT becuase I suspect it is hardware related.

I have an early 2009 MacPro4,1 model. I can't run AHT because:

1. I lost the original sofware DVDs

2. It is no longer on the hard drive after having upgraded the system multiple times.

3. I called Apple support to try and order the original system software and they told me they can't provide it and only have retail disks which don't have AHT.

4. I found a blog post that links to download AHT for various models, but MacPro4,1 isn't listed: http://rivenbyfive.blogspot.com/2012/01/download-and-run-apple-hardware-test.htm l

I'm not sure what to do at this point. Since I don't have my original disks it seems like Apple has made it impossible to run AHT on my upgraded system.

Any ideas?

Mac Pro, OS X Mountain Lion (10.8.2), Early 2009 Mac Pro

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.
