The IAT sensor is the small black sensor that's pushed into the inlet tube of the air filter system. Here's a picture...



It would have to be tested with a scanner to see if it's bad.

The other (High Speed Cooling Fan Circuit), I would think if that wasn't working, you would have some signs like overheating when your sitting at idle. Try turning on your A/C and with the engine running, sit at idle for about 10 minutes. Watch your temperature guage. If it starts going over half way towards HOT, you might (probably do) have a fan motor problem.

Just thought I would chime in on your IAT high voltage code...

I had that same code when I had a vacuum leak...check to make sure that you don't have one. My PCV valve hose cracked out from my vacuum gauge, and that threw the code.
