I stopped by Diesel Performance of Utah the other day, and Ken and I got talking about the IAT sensor in the 03. The IAT/MAP are all in one on the 03's. Ken pulled mine, located on top of intake, about 6" rear of the intake horn, 2 TX-15 screws, and pulls right out. With 75K, and 60K with the exhaust brake, mine had a very little dry black powder on it, after spraying it with brake cleaner, did not change appearance at all. We shouldn't have problems with it any more.
Just thought you all would like to know.
