Where is my iat sensor on 4.3


The sensor is in the black rubber tube that connects your intake plenum (top of engine) to the air breather tube that comes from the air filter. The sensor is on the underneath of that rubber connector described above.

Where is IAT sensor located on 2004 f350 5.4L V8


2004 Heritage & Lightning ( guess this is your config, with posted in 2003 section ).

Looking at the engine, the air filter housing is the large round tube on the right hand side ( driver's side or left when reading descriptions )
The IAT is in the pleated section of the intake ( factory intake ) to the left of the air filter, about where the power steering fluid reservoir is at ( it should be pointing towards the back of the truck ).
Small black connector with a plastic wire loom on it.

2004 Non heritage ( New Body Style ) :
It is on the side of the large housing that holds the air filter ( on the stock intake, not a FIPK kit from K&N or the likes ).

Looking at the engine, the air filter housing and tray are on the top ( 2 latches hold the air filter tray in ), on the right hand side just behind the top of the T shape ( looking down on it ).

The connector should be black with a trace of red on it.

Cant find IAT on 99 jeep grand cherokee laredo...


Intake Air Temperature sensor.

It has to be installed ->BEFORE the throttle body, to sense the density of the air entering the intake manifold, based upon intake manifold temperature.

It provides an input voltage to the PCM, (Powertrain Control Module)
It's a Negative Thermal Coefficient sensor, (NTC. It uses two wires)

Meaning, as intake manifold temperature Increases, resistance in the sensor increases.
(Less voltage)
As the temperature Decreases, resistance in the sensor Decreases. (More voltage)

The PCM then uses this input to calculate the following;
1.Injector-Pulse Width
2.Adjustment of spark timing.

Just thought you might want to know.

Wish I knew what size your engine is.
A. The IAT in the 3.7 Liter engine, is located in the Left side, {Drivers} of Intake Manifold Plenum. (BEFORE the throttle body)

See that plastic 'snorkel' tube, that comes from the air cleaner housing, and goes to an oval shaped aluminum housing? That oval shaped, {On the end}, housing is the Intake Manifold Plenum.

The 4.7 Liter engine has the IAT in the same place.
The 4.0 Liter has the IAT installed INSIDE, the Front of the Intake Manifold Plenum. (Before the throttle body)

The color of the two wires are Brown with a Yellow stripe, (Thick 20 gauge wire), and Black with a Red stripe. (Thinner wire. 18 gauge)

Code came back as iat sensor reading high


IAT stands for Air Intake Temperature Sensor and it is located in the intake tube coming from the air filter box tot he engine. Easiest way to find it is look at the top of your engine where it says 2200. Coming right out of that manifold is a black ribbed tube about the size of a baseball to softball. It should be going towards the direction on the front drivers side. on the back side of that tube, about 4 inches away from the intake manifold (the things that says 2200) is a plug with wires. That is your IAT Sensor. If it is unplugged, plug it back in. Otherwise unplug it and replace it. Make sure to disconnect the battery while you do this so the computer resets itself after the new one is installed. Thanks and please don't forget to rate!

2001 malibu shifts rough


code p0113 means: IAT sensor high temp

and the solution:
The Intake air temp sensor is located inside the air flow meter and uses yellow and black wire and the black wire. IAT sensor circuit code P0113 indicating excessively high voltage or (Open Circuit) the ECM is either not seeing the correct voltages at terminals 66 and 80 under the dash at the ecm. It could be as simple as a broken wire under the insulation right at the air flow meter, Or a little worse a bad air flow meter. There are cheeper remanufactured Aair flow meters available at Nissan for your car around $150 instead of $400 like they used to be new.
