I need to locate the IAT sensor so I can attach a performance chip to it.
Hi Terry:
The IAT sensor is a thermistor which supplies intake air temperature
information to the PCM. The IAT is located in or near the air intake duct.
Fig. 1: On VIN 8 engines, the MAT (or IAT) is mounted in the intake plenum
Fig. 2: On most vehicles, the IAT sensor is threaded into the throttle body extension
Hope this helps; also keep in mind that your feedback
is important and
I`ll appreciate your time and consideration if you leave some
testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

The IAT sensor should be located in the air inlet tube to the throttlebody
SOURCE: cant find the iat sensor on 91 s10
The IAT or MAT sensor (as equipped), is a thermistor (resistor which changes value based on temperature) mounted either in the air intake snorkel or the manifold (depending on the application).

Yes. That is exactly it. The Air Intake Temp Sensor is built into the Mass Air Flow Sensor on the Air Filter Box. Below is a picture...
I personally have not connected one of these Chips to a Tahoe...What I can provide you with, is the Connector Diagram so you know exactly what Wires you need to Splice in to. See below...
I hope this helps you. If you have any more questions or need any more diagrams, please don't hesisitate to ask...Thanks again, JShreader.
Save your money, the chip is a ohm resistor at Radio Shack for under $2.00. It splices in to you IAT wire harness located at the intake tube between the air filter housing and throttle body.
Problem with this system is, that you can not adjust anything and have to run a constant 91 octane just to make sure you do not have a Detonation. The ECM will catch the Detonation from the knock sensor and compensate for it by retarding the timing which in turn lose of HP till next start up.
If you like and don't mind the check engine light on once and awhile, you can do the same by just disconnecting the IAT wire harness which give the ECM a 0 resistance thinking it's -20 out side and turn the timing up and lengths the injector pules.
When i was running a Nitro in the Toy before i sold it, i had installed a 10K ohm Potentiometer which you can buy at radio shack for under $5.00 i believe, I just spliced it in to the IAC wire harness so if i wanted to play with the Nitro I'ld turn the resistor up making the engine think it's 185 degrees F and would ****** the timing so i would not hurt the engine. But if i wanted to get more timing i would just turn the knob to drop the resistance to get more time since the engine thinks it's -20 out side.
Hope this helps. Keep me posted if you need more info. Best thing is to do a dyno tune and you can change everything right down to the Shift points.

The iat looks like the mass air flow its a hard plastic cylinder that connects to the intake tube after the air cleaner

Just keep in mind, on earlier model vehicles, the sensor is referred to as the Manifold Air Temperature (MAT) sensor.
