2006 Ford Expedition 5.4L V8 Location of Intake Air Temperature Sensor I.A.T

It's under the intake in the side of the cylinder head no engine size given

Doesn't have one ,has a mass air flow sensor .

you don't have a MAP sensor, but you do have a MASS AIR sensor that is on your intake tube between your air filter and the throttle body.

I believe they are located in the intake manifold somewhere. Make sure the one that tells the computer the coolant temp is ACTUALLY giving out the correct temperature. I had a bad one one time in a 1993 Ford F-150, 5.8L....... no check engine light came on but hard to start. The bad sensor was telling the computer it was 32 degrees F when it was almost 80 degrees outside.!!
Garbage in=Garbage out.

Here is a video link from Youtube. There are 2 sensors, 1 for the guage and the other tells the on-board computer how hot/cold the coolant is. The one for the guage has 1-wire and the other one has 2 wires.
Hope this helps, ask more if you need to. What kind of problem are you having? No heat inside? Guage needle not getting into the normal area?

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.

Location of Intake Air Temperature Sensor:
The intake air temperature sensor, which is mounted on the mass air flow meter, monitors the intake air temperature. The intake air temperature sensor has a built-in thermistor with a resistance that varies according to the temperature of the intake air. When the intake air temperature becomes low, the resistance of the thermistor increases When the temperature becomes high, the resistance drops .

Idle Air Control (IAC) Motor OPERATION The IAC motor is mounted to the throttle body and is operated by the engine controller. The throttle body has an air control passage that provides air for the engine at idle (when the throttle plate is closed). The IAC motor pintle protrudes into the air control passage and regulates air flow through it. Based on various sensor inputs, the engine controller adjusts engine idle speed by moving the IAC motor pintle in and out of the air control passage. The IAC motor is positioned when the ignition key is turned to the ON position.


OPERATION Found on V6, V8 and V10 engines, the intake manifold air temperature sensor is a variable, thermister type which reacts to temperature changes. In cold air, its resistance is high. As temperatures increase, its resistance decreases.

The sensor element itself extends into the intake manifold air stream to provide input voltage to the engine controller. This signal is used along with signals from other sensors by the engine controller to determine the fuel injector pulse width.
