Pcm uses maf input to calculate how much air is entering into the engine. Depending on the year your Iat may be integrated into maf sensor. You should replace it. Just to be sure, Maf is sensor in Intake tube between air filter and turbo - not sure how you could break that.

Do you know what years this is true on? I've been trying to figure out if the IAT temps I'm reading on my scangauge are from the MAF or if the sensor is located elsewhere.

Not sure what years had a seperate iat sensor. It would be located in the air intake tube between air filter and maf sensor. It's a 2 wire sensor.

There are two IAT sensors. The first is in the MAF measuring "ambient" temp. The second is on the intake manifold reading actual air temp going into the engine.

There is a third air temp sensor for the temp readout in the dash.

What air temp readout on the dash? I think your talking about the coolant temp sensor which is on the oil cooler cover.
