More detail photos of this air temperature sensor:

I can see the text : KEC. I guess Korea Electronic Company.
“Goryeo” is very similar pronunciation to “고려(Goryeo)”
but usually people write in English “Korea”.
Actually Goryeo is one of Korean dynasties. It’s before the Joseon Dynasty.

There is texts :
AT 4

If you know what AT 4 MAB means, please comment.

The terminal has 2 pins.

Regarding air temperature sensor, I found the below information by googling.

The Intake Air Temperature sensor (IAT) has been utilised as an Engine Control Unit (ECU) input signal from the very first EFI systems to the currently used systems, as a requirement for calculating the Air Mass volume for the incoming air charge.


The Intake Air Temperature sensor is usually mounted in the intake manifold so the tip will be exposed to air entering the engine. … The air temperature sensor is a thermistor, which means its electrical resistance changes in response to changes in temperature. It works the same as a coolantsensor.


You can see in youtube where it is located and how test it.
