I may have one lying around because I replaced mine after getting an IAT code. Turned out the sensor was fine and it was the IAT harness that was bad. It's a fairly common problem. Do some searching and you may find something.

9 times out of 10 it's the harness, not the sensor. The part number for the harness is in one of those threads.

It consists of the plug that the IAT sensor plugs into and about 12" of the wires that come out of that plug. You snip the IAT harness wires off about that far back and solder the new harness in/shrink wrap/etc.

Problem solved!
