The intake air temperature sensor on a 1992 Toyota 4Runner will be found on the intake system. The unit is clipped into the plastic piping of the intake.
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.
In the intake. (Intake Air Temperature)
It should in the air filter box or if you have a MAF sensor, the intake air temperature sensor is a part of the MAF.
Check the air filter box.
It's inside the air cleaner housing.
The 1998 Toyota Corolla air intake temperature sensor can be found on the air intake hose. The air intake hose will come from the air intake box and proceed to the engine.

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.
