Recently, my vehicle started acting up. It turned off on me a few times when I came to a stop at a streetlight then the "Check Engine Light" came on. I used my FIXD OBD-II Code Reader and it gave me a P0113 trouble code as you can see in the title. I also took a screenshot of the trouble code on the app. I have looked online for the Intake Air Temperature sensor and I have found a few different versions of it for my specific vehicle. I am not very sure which is the correct part and also exactly where this sensor is located on my truck as I cannot seem to find that information online. Note that a while back a "Check Engine Light" came on and it was for the mass air flow sensor which I have replaced and that trouble code light was removed. I also have attached images of the three different IAT Sensor from AutoZone for this specific truck and I do not know which one is the correct part. Help!

Hello,

Your vehicle's Intake Air Temperature sensor (IAT) is part of your Mass Airflow sensor (MAF). In the diagrams down below I have included diagrams, description, and step by step factory diagnostic troubleshooting guide for the MAF/IAT sensors, as well as the Original Equipment Manufacturer (OEM) part number for the MAF/IAT sensor.
Please go through this information and get back to us with what you are able to find out, please.

Thanks,
Alex

Thank you so much for this information. So I would have to replace the entire Mass Air Flow unit as the IAT sensor is built in it?

I replaced the MAF sensor last year because a trouble code appeared reading that it was the problem. Now it is the IAT sensor, why does AutoZone have those parts that do not look like those diagram images? They do not look like they are part of the MAF sensor but a sensor of its own.

Hello,

I am not sure of that. I have information for you about the Intake Air Temperature sensor (IAT) from one of our resource guides for a 2005 Nissan Armada (they do not list a 2004 Nissan Armada), and I have a complete set of engine controls for a 2004 Nissan Armada from the other resource guide we use. Both of them are included in the diagrams below, and both say the same thing, which is that the IAT is built into the Mass Airflow sensor (MAF) on your vehicle. Please go through the resource material from the diagrams below and get back to us with what you are able to find out, please.

Thanks,
Alex

I believe you could not find a 2004 Nissan Armada because my truck is an 2004 Nissan Armada Pathfinder, so it is a bit rare "I guess" I am not really sure. Even 2CarPros did not give me the option of the "Pathfinder Armada", maybe try looking for it that way? I would think it is the same engine though.

Hello again,
Let's make sure. I have included the information that you requested in the diagrams down below. And yes, It is the same. IAT sensor is in the air box and the MAF connector contains the IAT wires as well. Please get back to us with what you figure out.

Thanks,
Alex
