The Intake Air Temperature (IAT) sensor detects the temperature of the incoming air stream in a car machine. The IAT sensor resistance changes in response to the intake air temperature. The AIT is usually located in an intake air passage which is connected to the THA terminal on the ECM, it is used for detecting ambient temperature on a cold start and intake air temperature as the engine heats up the incoming air. The sensor resistance decreases as the surrounding air temperature increases. This provides a signal to the PCM, indicating the temperature of the incoming air charge. The following schematic shows the Typical Intake Air Temperature (IAT) Sensor Circuit Diagram.

need to know what wires lead to the MAF/IAT sensor to hook up a gforce chip please
August 17, 2011 @ 11:01 pm
I need a wiring diagram of where the wires lead to. mine has gone bad but i replaced the sensor and it’s still bad, i checked the voltage output. it’s 0 so it’s not reading at all which i’m guessing that means there is a break in the wire. please someone let me know, it’s noticeably robbing my gas and making my car a pain in the ass to start in the morning.

Recently purchase a chip from autochipsdirect.com for my 2010 Nissan Rogue SL AWD 2.5L. I am having trouble with the installation. I need to “piggyback” off the IAT sensor wires which are integrated into the MAF sensor but, I am not sure what color these two wires are nor the correct location of the wires in the MAF sensor. If someone could help with this, I would greatly appreciate it. Thanks.
