I've been having problems with my early 2009 mac pro freezing and having to hard reboot.  I ran Apple Service Diagnostics and 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 -

 

 

Does this mean I need to replace the logic board?
