Question about 1995 Geo Tracker

1 Answer

Any Photo or Diagram of location of Air Temperature Sensor/IAT/MAT etc;


Help I bought the eBay performance Fuel Saver CT-700 "chip" for the 1995 1.6 / TFI that add's 25 MPG's & add's 70+ HP, but can't seem find out the location to put the diode on the vehicle's air intake,or manifold.

I think I've been ripped off .99c grrrrrrr.

Thank's for any help in addvance.

Where is iat sensor on 2006 toyota tacoma 4.ol 4door located ?


This is the 2001-2012 Toyota Tacoma wiring diagram, Toyota Tacoma IAT (Intake Air Temperature) Sensor Location and the Toyota Tacoma MAF (Mass Air Flow) Sensor Location, also included is a pinout of the sensor. You are likely installing a performance chip or a cold air intake kit for increased HP (Horsepower). You will want to be sure to disconnect the car battery before adding performance products.




Here is the Toyota Tacoma's Iat sensor diagram:

Where is the IAT sensor on the 1993 corvette


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.

Need to wireing diagram for iat sensor


Vehicles: all computer-controlled internal compustions engines equipped with an IAT (Intake Air Temperature) sensor

Intake Air Temperature (IAT) Sensor

Operation - IAT

This sensor is a resistor based sensor which detects the intake air temperature. According to the intake air temperature reading the ECM/PCM will control the necessary amount of fuel injection.

ECM = Engine Control Module (aka "the car's computer")
PCM = Powertrain Control Module (aka "the car's computer")

Where is the IAT sensor


The Intake Air Temperature (IAT) sensor is the same as the Manifold Air Temperature (MAT) sensor on earlier models. IAT is located in or near the air intake duct (click image for zoom).

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.

Locating the iat sensor on a 2003 dodge 5.9


The IAT sensor is along the intake tube before the throttle body. If your planing to buy the performance chip from EBAY or any other place, save your money. You can go to Radio shack and it will cost you less then $3.00 for the resistor needed to make your own "performance Chip" IF you like you can use and 10K ohm potentiometer wire it through to the IAT sensor wire harness so you can adjust your timing for the type of fuel you want to use or how much performance you want out of your engine. Here is a link to the installation of the resistors and the different resistor's you can use or like me use a Potentiometer. Note if the timing is to high on hot days, the knock sensor may trigger and the engine will power down 15% till next start up. Good luck and hope this helps. http://kingenterprises.net/IAT-Timing-Tricker.htm

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 cant locate the iat and the maf sensor wires on my car.


I can tell you that the mass air flow sensor is up front on the drivers side of the engine. It will be located on top of the round black tube that runs behind the air cleaner box. The IAT, or the IAC valve should be located closer to the engine towards the end of that same tube. That's where the throttle body is located. I would suggest going to your local library and referencing a Mitchell or Chilton repair manual if there is one available for that new of a model.

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).
