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.

I am installing a performance chip and need to know the location of I.A.T sensor. Surburban,1500,350 engine,[5.7ltr.]


  • It may be built into your mass airflow sensor (if its not in the air intake tube. Reference:chev tech
  • I hope that is not one of those chips you can get on ebay, real they are a waste of money. there is not much you can do to improve fuel mileage.

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...

Where is the intake air temperature sensor?


if you look in the air intake boot you should see a two wire sensor stuck in it. this is the iat. That being said i dont recommend the "chip" you are referring too all it does is make computer think it is cold outside all the time so it adds more fuel to engine this is were they claim the extra power. decreased mileage and decreased engine life.a programmer works much better.
