Follow the plastic tube from air filter box to your engine. The iat is closer to the air filter box, you will see a large connector attached to sensor.

94 isuzu rodeo mat sensors location

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.

Where is the iat sensor located on a 1999 chevy cavalier 4cyl

The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.

Where is the MAF Sensor and the IAT Sensor on my 99 dodge avenger, i cant seem to find these 2, if someone can kindly instruct me to find, i will be greatly appreciated

IAT is located beside the throttle. This engine does not have a mass air flow sensor the computer uses the inputs from the IAT, MAP (Manifold Absolute Pressure) sensor and the RPM reading to determine what the air flow reading would be.
