EcoDiesel - Unidentified DTC - Intake Air Temperature

Hello, this forum is great. I have been having an issue with my new 2014 Ecodiesel Grand Cherokee and I was hoping I might get some insight here.

Primary Question: Any ideas where the Intake Air Temperature Sensor 3 is located on the Ecodiesel?

Background:
I have 1000 miles on it and it has been throwing an error code "P00EA" on an intermittent basis that sets off the "Service Electronic Throttle Control" warning and reduces power.

I have taken it to my local dealer once. They performed a few RRTs on it and said it was fixed. On my way home it set the same error. I have been tracking the data via a scanner and have some interesting data on it.

Intake Air Temperature Bank 1 Sensor 3 has been very erratic. Going from 70 degrees to 450 degrees for short amounts of time. The dealer didn't figure the problem out and I would like to take a look at the sensor connections myself. However, I'm not sure if "Sensor 3" is part of the MAF sensor on the air intake right after the filter or not. The specific DTC "P00EA" didn't even show up on multiple list of codes I could find online. The only spot I could find it was in a blog referencing Duramax Diesel engines here: New 8-Pin Mass Air Flow, Humidity, BARO and Intake Air Temperature 1 and 2 Sensor

Any ideas where the Intake Air Temperature Sensor 3 is located on the Ecodiesel?
