What is the intake air temperature sensor?
What is the intake air temperature sensor?
The intake air temperature (IAT) sensor, otherwise known as the air charge temperature sensor, is used by the powertrain control module (PCM) to determine the temperature (and therefore the density) of air entering the engine. Typically, the PCM sends a 5-volt reference to the IAT sensor.
What does the intake air temperature sensor do?
The Intake air temperature sensor or IAT sensor has the core function of monitoring the temperature of the air that is entering the engine of your vehicle. This information is very useful for the engine control unit or ECU for many functions and calculations, such as calculating the air density for effective ignition timing and fuel efficiency.
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.
Where are the air temperature sensors located in a car?
One sensor is used to monitor the temperature of air inside the passenger compartment, while another measures the outside air temperature. A standalone IAT sensor is located between the air intake box and the throttle body in the air intake passage of most vehicles.
How to check intake air temperature ( IAT )?
To use the scan tool, you need to perform the following steps. Attach the scan tool to the vehicle, and turn on the engine. 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.

What should intake air temp be with engine off?
With the engine off, measure the sensor resistance across its terminals. At about 68 F (20 C), you should get around 37K ohms At about 86 F (30 C), you should get around 24K ohms Plug in the sensor electrical connector.
