What is IAT in automotive?
What is IAT in automotive?
The Intake Air Temperature (IAT) Sensor is used by the engine’s Power Control Module (PCM) to decide at which rate the engine should spark and inject fuel to obtain optimal performance.
What are the color standards for electrical wiring?
For wires that will be 120, 208 or 240 volts, the following wiring color standards are used. It is important to note that with this type of wiring, there are multiple phases in place, each of which will get its own color wire to make it clear what it is for those working on it.
Which is the IAT sensor on the manifold?
The iat sensor is the front sensor on the intake manifold it has a gray 2 wire plug that is the 4.0 lt the 2.5 the sensor is the back sensor on the manifold.
What should the resistance of an IAT be?
That being said, as you may deduct so far, if you want the computer to “think” that air is colder than it really is, then a reading of a higher resistance from the IAT is what we are looking for. Many IATs go as low as 200 Ohms when hot around 100 degrees Fahrenheit and go up to 5000 – 7000 ohms at low temperatures like 30-50 degrees Feranheith.
Where is the IAT located on a car?
Most vehicles have their IAT = Temp sensor located on the air intake track of the vehicle. It will have 2 wires going to a plug mounted on the air intake track or air intake manifold of most vehicles.. If you cannot find your IAT and your car is 2000+ , then it maybe built into your MAF = Mass Air Flow meter and will have 4-5 wires going to it.

How to see the color of a connector?
For viewing connector pin outs, with two ter minals or greater, refer to section 8W -80. This section identifies the connector by number and provides terminal numbe ring, circuit identification, wire colors and functions. All connectors are viewed from the terminal end unless otherwise specified.
