Mac Mini AHT Error

Hello,

I've got a Mac Mini running 10.5.6 that kernel panics.  The fan seems to run at full speed all the time. I ran Apples Hardware Test and received the following results:

4SNS/1/40000000; TA0P-128.000

After a bit of googling, it seems the first part indicates a sensor fail of some kind. If it is a temp sensor, that would explain the fan. However, I've also seen reference to a logic board issue.  Can anyone shed any light onto the remainder of this error code?

Thank you
Rob

Problem Solved.... disassembled and found disconnected jumper labeled j6400. A quick search led to this site: http://www.macminicenter.com/wiki/index.php?title=Core_Internals:Connectors which identified it as a fan temperature sensor connection. Reconnected it and all is well :)
