Is a 94 Chev K1500 equipped with a IAT or Mat sensor? If so, where is it locAted?

mat?
why ask engine questions with no engine stated??????
the old name for IAT (manifold air temp)
new name is Intake air time.. not arguing names.. but using real name puts me on track.
why do easter egg hunts from pro retired mech.s.?
why do that. and not stating symptoms.
NO ENGINE stated, which one?
some engine do not have one. even with EFI.
that is a FACT. ( I had a 92 that has none)

they removed manifold(M name) because the sensors are mostly on the air cleaner box now, true inducted air , temperatures. work best !!!

usa car or canada?we cant guess that.
and they are different. in many ways....
on some engines, the IAT is hidden inside the MAF sensors. (a fact on many)
but no engine or country stated, so can't guess.
that.
even
This vehicle was sold as the Holden Rodeo in New Zealand and Australia.
but yours is in N.Americia right? this is a USA forum
and no one ever states their country and smog parts, vary by you guessed it , country....... and their smog laws... BIG TIME.

------------------------------------------------
USA answering (wild mostly useless guess)
engine 2.6L or 3.2Liters?
some 2.6L have a MAF sensor. (other use a MAP)
the IAT is very important on the MAP engines, but not on any MAF.
"speed density and air density system " they can be 1 or other.
and matters big time.

ill look at alldata.com (usa only it is) for you. done.... (so can you,log in read)
ok, im there,
2.6L has mAF, no MAT (IAT) there, that means the MAF does all that on one part. (measures air flow and corrects air measurements with its internal temperature sensor device inside MAF) (magic?)
now the 3.2L bingo it has a MAP engine and has IAT.
there are other engines....

below is 3.2L IAT (E loc)
end easter egg hunt..... on other engines, its on the air cleaner. or none AT ALL.
Post symptoms and get real help.
say dont want guessing what tests. !!! and win.

See if this helps -

94 ford ranger mass air sensor the iat sensor

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.

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).



Fig.: On 1996-98 vehicles, the IAT sensor is mounted in the rear air intake duct


Hope this helps (remember to rate this free answer).

The IAC motor is located on the throttle body, mounted sideways and looks like this;

Are you aware you can't really test this without the correct impedance meter You can ohm the sensor. But you will need to see how it responds while the car is warming up and you will need an laser to test for temp. I'm just letting you know that these newer computer in cars can be damaged easily with the wrong meter.
Good Luck

IAT is incoming air temperature sensor. Look from intake air hose/duct up to throttle body, for sensor that sticks into side or top of ducting that airflow coming in through there, or at front of throttle body area.

I assume you are looking for the wiring for the IAT because MAT sensors are no longer used..

here you go

black / white - PCM ground
pink - fused 12-volts
yellow - MAF signal
tan - IAT sensor signal
black - IAT sensor ground

manifold temp. sensors are no loner used.

I believe you are looking for the IAT "intake air temp sensor" which is part of the mass air flow sensor.

good luck

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).

most of times it is located on the big breather hose after the air filter
