Iat sensor location on a 91 d21 truck - 1992 GMC Suburban

The IAT (Intake Air Temperature) sensor is plugged into the Air-Cleaner housing. One end of the sensor will be found held in place by a rubber grommet and the other end will have a two wire plug attached to it.

This should help. How to Test the Intake Air Temp IAT Sensor GM 4 8L 5 3L 6 0L

Hi Terry:
The IAT sensor is a thermistor which supplies intake air temperature information to the PCM. The IAT is located in or near the air intake duct.



Fig. 1: On VIN 8 engines, the MAT (or IAT) is mounted in the intake plenum




Fig. 2: On most vehicles, the IAT sensor is threaded into the throttle body extension

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

The Mass Air Flow (MAF) sensor/Intake Air Temperature (IAT) sensor is located in the air cleaner case.

The Intake Air Temperature (IAT) sensor is an integral part of the Mass Air Flow (MAF) sensor. Looks like this:

For Hyundai Car 1999-05 - Intake Air Temperature (IAT) Sensor Location (check several options):

1.- The IAT sensor is located against the firewall to the left side of the engine. It is combined with the Manifold Absolute Pressure (MAP) sensor.

2.- This sensor is located in the air intake plenum assembly. On some vehicles this sensor is combined with the MAP/MAF sensor.

3.- The IAT sensor is located in the air plenum assembly. On some vehicles it is combined with the MAF sensor.

4.- This sensor is located in the air intake plenum assembly. On some vehicles this sensor is combined with the MAP/MAF sensor.

5.- This sensor is located in the air intake plenum assembly. It is combined with the Manifold Absolute Pressure (AFS) sensor.

6.- This sensor is located in the air intake plenum assembly. It is combined with the Manifold Absolute Pressure (AFS) sensor.

Hope this help (remember comment and rated this) TY for using Fixya.

The iat looks like the mass air flow its a hard plastic cylinder that connects to the intake tube after the air cleaner

The IAT or MAT sensor (as equipped), is a thermistor (resistor which changes value based on temperature) mounted either in the air intake snorkel or the manifold (depending on the application).

it is the air Intake Temperature Sensor located at the air cleaner housing.
