IAT sensor location - Grand Cherokee Jeep Cars & Trucks

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.

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:

The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.

Hope helped.

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.

Try “autozone.com” or your local library for diagrams and step by step instructions.

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