It is heated to such a high temperature by going over the engine which is really hot and is part of the cooling system, the cold air goes over some part of the engine and comes out hot. It is part of the cooling system of a car, so therefor if your car has overheating problems turn the heater on.
I don't think it has a IAT sensor, but it does have a temperature vacuum switch to work the heated air door.
Code P0113 indicates a intake air temperature sensor circuit high output. Check the connection to the intake air temperature sensor and if that is fine consider replacing the intake air temperature sensor.

INTAKE AIR TEMPERATURE SENSOR HIGH
The intake air temperature sensor can be found on the top of the air intake manifold. The temperature sensor should be labeled as such.
The intake air temperature sensor on a 1991 Honda Civic is found on the intake. The intake air temperature reads to climate of the air that is being sucked in through to the engine.
Trouble code P0113 means: Intake air temperature circuit high input
as intake air temperature increases it lead to decreas in i.c engine efficiency. as engine efficiency is ratio of difference in intake and outlet temperature to intake temperature.
Trouble code P0113 means: Intake air temperature circuit high input
Yes, most if not all 90+ efficient furnaces are designed to take primary or combustion air from outdoors. That is partly where they get their high efficiency rating from. They are not using air that has already been heated for combustion.
The intake air temperature sensor on a 2005 Subaru WRX is part of the mass air flow sensor. It is located in the air intake duct.
The intake air temperature sensor is located on top of the intake. In a 1990 Toyota Camry the air temp sensor assures the ECU the engine is running at optimal temperature.
