Faulty IAT sensor or faulty MAF sensor ?

[Martonator]

Hello everyone !
So I got information from my mechanics that my MAF Sensor runs improperly and also the IAT Sensor gives wrong information about the temp.

So I was looking and looking for that IAT sensor but many people told me (also i saw in the forum) that in many MAF sensors , the IAT sensor itself is a part of the MAF.

I will upload photos to show you my MAF Sensor and my Engine bay so if you guys can tell me if the IAT is separate part or it is integrated with the MAF Thanks !

The vehicle is Korean but the engine is one by one 6-bolt 4G63 N/A

The Factory MAFs for DSMs have the Intake Air Temp (IAT) sensor inside along with the Barometric Pressure sensor and the Karmen Vortex Sensor. I can't say what Kia did but if the sensor output is on the connector for the MAF it's a good bet it's in the MAF.

Could it be faulty ECU because some people told me that too ? I don't think so cause my MAF sensor gives lower air intake pressure and if the IAT sensor is combined with the MAF then the IAT/MAF gives me -40*deg. celsius of air intake temperature ???
