I can't seem to find the Air Intake Temperature sensor on my infiniti fx35.
The only thing I was told was that it was close to the throttle body, but the only sensor I can find is the Mass Air Flow sensor, it has five wires going to it.
Thank you very much for your time.

Re: Can't locate IAT sensor on 04 fx35
Well first of, what are you looking for the AIT?
But anyways, the AIT should be in the MAF Sensor. Hence all the wires.
OK so i havent taken apart a MAF sensor and neither should you, its a pricey item.
But I do know this; An AIT is an NTC sensor meaning that when tempurature goes resistance goes down and when resistance goes down Voltage goes up. Now one thing you can do is find a wiring diagram of the maf sensor and the vehicles computer. And on there it will show you which wire goes to the AIT.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

P0111 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Range/Performance Problem. It is very likely the sensor got disconnected during some service work like replacing the engines air filter. Other causes- Dirty air filter - Intake air temperature (IAT) sensor harness is open or shorted - Intake air temperature (IAT) sensor electrical circuit poor connection - Faulty intake air temperature sensor
P0113 - Intake Air Temperature Circuit High Inputhttp://engine-codes.com/p0113.htmlForum CodePossible causes- Dirty air filter - Intake air temperature (IAT) sensor harness is open or shorted - Intake air temperature (IAT) sensor electrical circuit poor connection or sensor has been disconnected in error - Faulty intake air temperature sensor When is the code detected?- An excessively high voltage from the sensor is sent to ECM.
DTC P0113 - Intake Air Temperature Circuit High Input.The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

The Mass Air Flow (MAF) sensor/Intake Air Temperature (IAT) sensor is located in the air cleaner case.

The Intake Air Temperature (IAT) sensor is an integral part of the Mass Air Flow (MAF) sensor. Looks like this:
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.
