Often, it is also installed on the intake manifold.
How does IAT work on a car engine?
IAT sensors must operate within specific ranges to send correct signals for the ECU to coordinate with the throttle position sensor, Manifold Air Pressure sensor, and Mass Air Flow sensor to adjust correctly for proper engine operation.

What does a faulty check engine light mean?
It helps monitor how much fuel is burned. A faulty sensor means it’s not providing the right data to the computer and causes a decrease in gas mileage. Most cars have between two and four oxygen sensors; the code you get from the scanner will tell you which one needs replacing.
After turning it on, check for the temperature of the IAT sensor. It should be 10°F above or below the ambient temperature of the vehicle. If this is not the case, you may have a problem with the sensor.
How does the IAT sensor help the PCM?
With the IAT sensor, it get’s to know the temperature of that incoming air and then is able to better calculate how dense that air is. Calculating the flow rate and density of the air that the engine is breathing at any given time helps the PCM maximize everything from fuel consumption to performance.
How is the sensor ground grounded to the engine?
The sensor ground is externally grounded to the engine, as well as to the ECU. The ECU is grounded to the engine also. We know that as the injector duty cycle increases, the average ground current of the ECU will also increase, and therefore so will the voltage drop between the ECU and the engine.
How to remove the IAT sensor from an air cleaner?
To remove the IAT sensor, detach the wiring harness connector from it . . . To install: Wipe down the air cleaner outlet tube and IAT sensor mounting boss to clean the sensor area of all dirt and grime. Install the sensor into the air cleaner outlet tube securely. Attach the wiring harness connector to the IAT sensor.
After turning it on, check for the temperature of the IAT sensor. It should be 10°F above or below the ambient temperature of the vehicle. If this is not the case, you may have a problem with the sensor.

What are the symptoms of a bad IAT sensor?
Symptoms Of A BAD IAT Sensor. The most obvious symptom will be the check engine light (CEL) lit nice and bright on your instrument cluster. The second will be an IAT sensor malfunction diagnostic trouble code (DTC) stored in the PCM memory.
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.
Can a bad intake air temperature sensor be repaired?
The chances are that your car’s intake air temperature sensor (IAT) is damaged and that it should be fixed immediately to avoid any serious damage to the engine. In this article, you will learn the meanings & the symptoms of a bad intake air temperature sensor.
