Ok 95 , must be 16v as only that engine has MAF.
the sensor is on the air cleaner box, has 2 wires. and the ohms
is on the below page. as is the full schematic, and the maf wiring
is the cel glowing key on , and off driving 20miles? if not post the flash codes. DTCs.
the iat is the least important in fact the 92 its MISSING !
the maf tests are here. too. many tests,
suzuki sells a maf for $1000 (dogs) and the china one is junk.
so test it carefully or go broke fast.
IAT and ECT ( both read same)

    the IAT is the least important sensor on any MAF engine. Unlike the MAP engine. that is why some years 92 it was not even there. (USA spec cars) if you need help testing the MAF, (or VAF) ask, btw never chean it by touching the hot wire, or closed, always keep 1foot away if using CRC MAF cleaner, as i use. CRC is a top USA brand. plastics safe....and all that...

    the tech reason for that is the MAF alone reads flow regardless of air temperatures. it is a calibrated instrument , too. thus , expensive to buy. (i find used ones , are best bang for buck)

    the MAF reads mass arr flow not just volume like the EU, VAF does, the USA spec care uses a real MAF , unlike many other countries. Geo's are sold to 8 countries..

Where is iat sensor located on 2006 tpyota tacoma 4,ol ?


Intake Air Temperature (IAT) sensor and Manifold Absolute Pressure (MAP) sensor are combined into a single assembly which is called Mass Air Flow (MAF) sensor. This MAF sensor is located on the air filter box near air filter hose, and is connected with a five wire connector. You cannot replace the IAT sensor alone. Instead a MAF sensor is replaced altogether.

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:

For a 2005 GMC yukon 5.3L what are the wire colors that control the IAT sensor There should only be 2 wires controlling it but there are 5 on the connection as it controls the MAF and IAT with the sa


The intake air temp sensor is part of the MAF sensor so yes there are 5 wires.
The two wires that go to the air temp sensor are tan and black. The other three are for the MAF.

Which are the functional iat sensor wires on an accordd 2008


It all depends on which engine your Accord is equipped with. This is really nice-to-know information when you are asking somebody for help with your engine control circuits.

For the 2.4L engine: At the MAF/IAT sensor connector, Pin #4, GREEN/BLACK is the "sensor ground" and Pin #5, RED/YELLOW is the "sensor input" for the IAT.

For the 3.5L engine: At the MAF/IAT sensor connector, Pin #1 GREEN/YELLOW is the "sensor ground" and Pin #2 RED/YELLOW is the "sensor input" for the IAT.

Exact location of the iat sensor on a nissan pathfinder 1996


The Mass Air Flow (MAF) sensor/Intake Air Temperature (IAT) sensor is located in the air cleaner case.
// // 0) preLoad.src = ctl00_cphLeft_chRepairTreeNav_tvTOC_ImageArray[i]; } ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.lastIndex = 34; ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.populateLog = theForm.elements['ctl00_cphLeft_chRepairTreeNav_tvTOC_PopulateLog']; ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.treeViewID = 'ctl00$cphLeft$chRepairTreeNav$tvTOC'; ctl00_cphLeft_chRepairTreeNav_tvTOC_Data.name = 'ctl00_cphLeft_chRepairTreeNav_tvTOC_Data'; //]]>

The Intake Air Temperature (IAT) sensor is an integral part of the Mass Air Flow (MAF) sensor. Looks like this:

Where is the IAT sensor on a 03 Ford Taurus,3.0L. flex fuel?


You don't change parts when you get a code. The codes are a starting point for diagnostic testing.
Codes are the symptoms of a possible problem,such as an out of range or defective sensor. Codes don't mean you change something. It's not that simple or are vehicles designed as such. You always test,then replace. You can't do either, if you don't know the system your working on.
The MAF and IAT Sensors are both in the MAF,one piece in most cases.

What are your issues ? Not likely a MAF gone bad.
Do you have the air filter cover on tight and no duct work leaks or vacuum leaks? That's what's possibly setting the code for the MAF.
