It is a sensor with 2 wires going into it located between air filter and throttle body.
IAT air intake sensor is a thermistor ( a resistor that varies the value of it's resistance in accordance with temperature changes ) the change in the resistance values will directly effect the voltage signal from the sensor to the PCM/ECM. As the sensor temperature increases, the resistance values will decrease. As the sensor temperature decreases the resistance values will increase.
The IAT sensor (Intake Air Temperature) is an integral part of the Mass Air Flow sensor.If the IAT sensor must be replaced,you must replace the MAF sensor
The IAT sensor, or Intake Air Temperature sensor, is typically located in the air duct between the air filter and the throttle body.
Underneath the drivers side seat, under the carpet.
There is a sensor located at the bottom of the coolant reservoir.
You do not, you have to replace it.
You will find the outside air temperature sensor under the battery tray
its by the under side of the radiator
On my 1998 Aurora with 4.0L v8, the air intake temperature sensor is located on the air filter housing on the driver's side of engine compartment.
In between the air box and intake manifold.
Depending on which one, it's in the dash or behind the grill.
how to change air temperature sensor on astra 2003 how to change air temperature sensor on astra 2003
The 1998 Toyota Corolla air intake temperature sensor can be found on the air intake hose. The air intake hose will come from the air intake box and proceed to the engine.
if it is like my 1998 it is mounted on the MAF sensor and must be replaced together as one unit
It is part of the mass air flow meter which is located in the air intake tube just after the air cleaner.
An air temperature sensor in an automobile is very important. The temperature sensor detects the external temperature. The external temperature is important because of the manner in which the car's computer mixes air and water.
If you remove your MAF (Mass Air Flow) Sensor, you will see there is a resistor just behind the MAF sensor on top...thats your Air Temperature Sensor.
