Where is the IAT sensor?

I had my car checked out because it kept throwing a SES light...and the mechanic said the air temperature sensor keeps popping out of the CAI. Is it that piece that plugs into the CAI with the little gromet?

Any pictures would be really great....and what do you guys think I should do so it does not pop out anymore

Thanks a lot

Yes it is that one behind the MAF. I used Duct tape to make a new little grommet. Works fairly well. Pretty ghetto though.

So has anybody tried those resistor chips? I got one for my car, but it says it replaces some wires on the iat sensor. I haven't put on yet thought not sure if it would hurt my car or not.

this is directly from 60degreev6 forum:

IAT stands for Intake Air Temperature. It is a simple thermistor that changes its resistance according to the temperature it is at. The idea beind this modification, is that by changing the resistance to that of a cooler interpreted reading, you will get more fuel. While it is true that you will dump more fuel...its false that this is a good idea. Running rich is bad for performance, so you are just wasting your time with adding more fuel in this fashion.

The stock computer already compensates fuel as it is, so trying to trick it into giving you more fuel is completely worthless. If you dump too much fuel, via switching to a colder resistance on the IAT while driving, you may even notice a puff of black smoke out the exhaust. Then, the O2 sensor will detect the overly rich mixture, and reduce the injector pulse width. This totally defeats the purpose or the IAT mod.
