SOURCE: DTC Code of a 1404 , and also a IAT High input malfunction

sounds like the IAT is disconnected, it is either in the flex hose from the air cleaner to the engine or in the air filter housing, on my GM product car it is in the air intake hose, it is small and has a 2 wire connector to it, just pushes and pulls in and out of the flexible air intake hose.

SOURCE: i have 2 pending codes for a 99' pontiac grand

Try unplugging and plugging the map sensor, this device should have manifold pressure hooked up to it, via hose, so check for cracks or leaks. Then clear codes and test again.

SOURCE: where is iat sensor located on 2000 mazda mpv van

the IAT sensor is part of the Mass Airflow sensor. here is a picture of that sensor.

Testimonial: "nobody where i lived could tell me this so thank you emissionwiz"

SOURCE: changed maf sensor because of p0113 code stillhave

P0113 is air temp circuit high. The maf sensor (mass air flow) sensor just measures the amount of air entering the engine. The iat (intake air temp) sensor is the one that detects the temperature of the air.
Change that sensor, and the code should disappear. It is located in the intake manifold or air plenum.

You don't change parts when you get a code. The codes are a starting point for diagnostic testing.
Codes are the symptoms of a possible problem,such as an out of range or defective sensor. Codes don't mean you change something. It's not that simple or are vehicles designed as such. You always test,then replace. You can't do either, if you don't know the system your working on.
The MAF and IAT Sensors are both in the MAF,one piece in most cases.

What are your issues ? Not likely a MAF gone bad.
Do you have the air filter cover on tight and no duct work leaks or vacuum leaks? That's what's possibly setting the code for the MAF.
