facing the engine, it's screwed into the right side of the intake manifold (big silver aluminum thingy with 2.8 numerals) just below those two hoses.

intake air temp sensor is inside the air cleaner housing. mass airflow sensor is on the air intake duct airflow meter is also on the air cleaner housing on 3VZ-FE V6 models
The mass airflow sensor and intake air temp. sensors are between air filter and throttle body
The airflow ambient temperature sensor is located on the air intake housing. The sensor should be labeled as the airflow ambient temperature sensor.
The intake air temp sensor and the mass airflow sensor both mount near the air filter.
The Intake Air Tmperature Sensor is incorporated in the Mass Airflow Meter.
The IAT ( Intake Air Temp Sensor ) is located intenally to the MAF (Mass Airflow Sensor). The dual sensor is between the air filter box and the engine. An electrical pluf is attached to it. TechJK ---------------------
Intake, in most cars it's 1 of the MAF's 2 wires. 1 is temp 1 is airflow.
When you open the hood the IAT (intake air temp) sensor is embedded in the air intake snorkel before the intake throttle body. If you were to take the air intake off you would have to take off the MAF (mass airflow sensor) connector and the IAT in order to do so.
There isn't one. It uses air intake temp, pressure and exhaust oxygen sensors to measure the AFR

The Intake Air Temp sensor is integral to the Mass Airflow Sensor (MAF). It cannot be replaced seperately. The MAF sensor would need to be replaced if you are trying to replace the IAT sensor. - TechJK -----------------------------------
