Can anyone tell me where my iat is located on my 2009 impreza. I know where the maf is but the chip I want to install needs to be installed on the iat sensor.

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:

You can go online to Free auto & truck manuals and get the right manual for your vehicle and it has wiring diagrams in the back of the manual usually. Hope that Helps.

havent a clue sorry.. contact dealer service for this..

ATTEMPTING TO LOCATE THE TWO IAT WIRES IN THE MAF SENSOR PLUG TO INSTALL PREFORMANCE CHIP IN a 2012 COLORADO 3.7 engine.

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..

If your planning on installing on of those so called chips, don't bother. It is just a .25 cent resistor that will cause more issues in the long run. Trust me on this one.

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.

The IAT is integrated with the MAF sensor on the 09 Fusion. The MAF is located near the air box on all three engines. on the driver's side, and will be held to some part of the intake tubing by 2 torx screws. http://media.photobucket.com/image/2009%20Fusion%20MAF/itsamecameron/fusion4cylengineMAF.jpg 2.3L shown, 3.0 and 3.5 should be similar.

its right next to the ignition coil,bolted right on intake

the iat is part of the maf sensor located in the air filter duct or housing. 6 pin connector. pin one color violet/gray is for iat. pin 2 is c-signal rtn yellow/violet. pin 3 maf yellow/violet. pin 4 maf rtn blue. pin 5 ground black/yellow pin 6 circuit breaker fuse 76 blue/brown
