What should the resistance of the IAT sensor be?
Now, to test the IAT sensor with a multimeter, you should measure the resistance of the sensor. If the multimeter shows a reading of 0 to 47 Ohms, then you have a problem with the sensor. The only thing remaining is to check for a circuit malfunction in the IAT sensor.
What should the temperature of the IAT be?
Disconnecting the IAT from the MAF should get the temperature reading back to -30 to -40°F. However, if this does not happen, it means that there could be a problem with the vehicle’s internal computer, which needs to be checked and solved by a technician. Connecting the 2 IAT wires with jumper cables should change the temperature to 300 °F.
Where is the IAT sensor located on the intake manifold?
It ensures optimum combustion and efficient fuel consumption. Where Is the IAT Sensor Located? The Intake Air Temperature Sensor is located somewhere on your intake pipes between the air filter and the intake manifold. It is often integrated with the MAF Sensor. Often, it is also installed on the intake manifold.
What should I do if my IAT is not working?
Connecting the 2 IAT wires with jumper cables should change the temperature to 300 °F. If this does not happen, it might mean that the wiring or the computer is bad. Now, to test the IAT sensor with a multimeter, you should measure the resistance of the sensor.

How to fix a bad intake air temperature ( IAT )?
If this does not happen, it means that the internal computer is to blame, and that it is not producing the voltage that the IAT sensor needs to function. To fix a faulty intake air temperature sensor, remove all carbon and oil accumulation. If this does not fix the problem, replacing the unit is the best option. Like it? Share it!
How to test the intake air temperature ( IAT ) sensor?
Testing the intake air temperature (IAT) sensor, which is located inside the mass air flow (MAF) sensor, can easily be done with a scan tool and/or a multimeter. In this article, I’ll show you how to test IAT sensor in a step-by-step way that will help you say that, ‘Yes, it’s BAD’ or ‘No, it’s not BAD’.
