Ok here is the situation I ran into... I got the service engine light coming on and when I got it checked it said that I have an open or short circuit condition or faulty IAT Sensor. I am not noticing any issues when driving the car around. I have also connected the computer to the car to reset it and the light comes right back on. Anyone have an idea on where the IAT sensor is located and how to fix it?

The IAT is actually part of the MAF sensor, I had the same problem a while back. After doing a manual ecu reset a few times it ended up going away,
