Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

SOURCE: IAT MAP MAF pics & locations

Go to alldatadiy.com and buy the car you are working on and you will have access for a year. This should have mechanical illistrations of what you are looking for. By the way that car does not have a MAP sensor.It uses a mass air flow sensor. Hope this helps...Dan

SOURCE: location of iat high input sensor

The iat (intake air temperature) is located on the air filter housing. If its reading high its probably unplugged

SOURCE: IAT SENSOR

what do you mean by control? there is one wire normally pink or white with pink strip that is power 5 volts + black is ground and a reference voltage 5 volts ground is black or white so the other two colors would be the control wires going to the computer. However would need the first 8 numbers of the Vin to know for sure. you can also go to www.alldatadiy.com and purchase a subscription that will give you the exact information you need, they change color codes for wires from time to time and if you hook it up wrong you can destroy the computer so I suggest you purchase the subscription to be sure.

For 2010 acadia, where is the location of 02 sensor fuse for bank 2 sensor 1?


O2 sensors do not have fuses as they are powered and grounded through the computer. if you have a code set for this sensor then you need to have the sensor checked or you can just replace it.

I would like to idenitify the different wires in plug going to IAT on my 2009 GMC Acadia


Why would you want to?? If your bought a chip for your IAC to try to get more performance and economy from your Acadia, all you bought is away to shorten up your service life of your engine.
IAT Sensor = “Intake Air Temperature” sensor AFR = Air/Fuel ratio, ideally it would be 14.7 units of air to 1 unit of fuel or 14.7:1
The IAT sensor is a passive or discrete electronic component that will simply vary its resistance depending on changes in temperature (also called a thermistor). It has a negative coefficient, meaning that the higher the temperature is, the lower the resistance it will offer to the current flow and vice versa.
Few ECUs will use the signal from the IAT sensor alone, to modify the ignition and / or injection to slightly compensate for the incoming air temperature variations. So making the computer “think” the incoming air is cold will make it do small adjustments to ignition timing and / or fuel injection and there is where the IAT Mod ideal originally came from.
It is accomplished by putting a fixed resistive value (fixed resistor) instead of the regular IAT sensor, simulating a cold intake air situation. Going back to the facts above, “the higher the temperature, the lower the resistance”, to benefit form this modification, we would need to make the resistor value high enough to make the computer “think” that the temperature is low enough. That would hopefully induce the ecu to inject more fuel and advance ignition timing accordingly, in an attempt to compensate the supposed incoming cold air.
The problem with the IAT modification: Even more and more people that have bought those IAT mods are claiming that it does nothing. It is probably attributed to the fact that not all cars depend only on the IAT sensors alone to make the necessary changes. So, it is very probable that modifying the IAT sensor of your car will do nothing, or at least nothing noticeable.
If you successfully modify the IAT sensor and the engine makes some noticeable changes, remember that the air will not be truly colder or denser, so no extra oxygen will really be present, ending up in a richer mixture, higher emissions and very probably lower performance, unless your car is already running way too lean because any previous modification or any existing engine problem and a richer mixture will benefit its performance.
If you live in a cold area, you will notice no difference as the original IAT sensor installed in your car will already be in a better resistance value than the one you would insert. If you live in a hot area (tropic, desert), it will be worse than the ones in a cold area, as even less oxygen will be available for the combustion. If you live in a high altitude area, you will have similar or worse luck that the ones in the hot areas as oxygen and pressure progressively decrease with altitude, even if it’s cold.
Regardless of the all mentioned above, if you finally make the car computer do a positive modification by installing that 10 cents resistor, remember that changes will be on the factory program range limits or specifications anyway, computer program is still the factory installed one. All changes made by sensor modifying (any sensor), will stay in the factory specs since sensors can be read but can not bypass or override functions in the ECU, unless a modified program (Dyno Tuned) is installed.
