SOURCE: IAT and MAF info

I have the same "chip" (really just a resistor). It should be the wire harness that clips into the lower box of the intake. I believe it is a green and a black wire. Just unclip it and slide the end of the resistor into each wire prong. Then tape the heck out of it. I put a rubber cap over mine then electrical tape. Works like a charm

They share the engine wiring harness from the computer (called the PCM) and a common ground circuit, which is referred to as the signal return. So I think you need to look for a defective ground.

What 2 wires for iat sensor


you lost the colors.? or are there 2 wires there that you know are IAT but dont know which pin fit them.?
no matter, either pin works.
the sensor is not electronic, its just a resistor, that is non polarized
the ECU sends current to the IAT, the current that flows, tells the
ECU what the air temperature is. in the intake.
no car year stated
no engine option stated in F150
so NO ANSWER exact , ever. (country helps too, but ill not say that it scares folks to death for some reasons)
Im in USA and ford does EXPORT cars and trucks.
the IAT is a thermistor, the FSm shows how it works and how
to test one easy, super easy, ask.

tell more get more.

2007 BMW 328i IAT Wire Colors in MAF Sensor


If you are installing a so called "chip" don't do it, it can harm the engine due the changes it causes in fuel control as related to Intake Air Temperature and burn holes in the pistons. All that little part really is, is a $.50 (50 cent) resistor that you can buy from Radio Shack, it is smoke and mirrors and it also will void any warranty you may have. I for one strongly advise against installing it, it will make not difference in power and all there claims are just lies and falsehoods..

I have 5 wires going to mt IAT sensor. i need to know which 2 wires lead to the MAF/IAT SENSOR.its a 2004 chevy tahoe z71 4x4 with a 5.3 liter v-8. im putting a computer chip on so need the color of the...


Well im not sure why you are asking this question . They are two differant systems the mas air flow and the idle air intake bolth run off a 5 volt referance voltage but are not related so to speak to each other as far as the same ref voltage the same ground as every thing else .The IAT MAP TP ECT and fuel pressure sensor are one side and the MAF EGR and the EVAP are on the other side but all on a common ground . Ex plain what you are trying to do and why you are trying to do it and mabey i can make your life a little easyer and what caused this problem

I want to know which IAT wires to tie into for my new performance Chip. I have a 1994 Toyota 4-Runner with the 3.0 Motor. Thank you. Oh yeah, there are 6 wires that I found. Only 2 go to the IAT.


That chip is a waste of time and money, and your mileage is going to suffer. Why dont the instructions tell you which wires? The THA terminal is wire color Yellow/Black. the E2 wire is Brown/Black.

Im installing a GForce Performance Chip but im trying to locate the AIT sensor. can you please give me its location, thank you for your time.


I'm installing a Gforce chip and I do know were the IAT\MAF sensor is located, but I still can not figure out which 2 wires I need to connect it to? I have the 5 wire sensor which ones do i need to hook up too. I do not get any reading on my multimeter.
And yes the battery is connected.

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.
