This 2012 Ford Triton V-10 6.8 liter is the engine for a 2013 Thor A.C.E. Motor Coach. I think I have located this sensor just past the air filter housing unit It is a 6 hole connection with only 4 wires that are Yellow/red, Gray,Black/white, and Gray/ brown. This unit is a flat cylinder with what appears to be an exposed diode on the end of the flat cylinder. Is this the MAF/IAT Sensor
That sounds like a Mass Air Flow sensor. Why are you checking it? What are your symptoms? Make sure your air filter is clean.
Save your money, the chip is a ohm resistor at Radio Shack for under $2.00. It splices in to you IAT wire harness located at the intake tube between the air filter housing and throttle body.
Problem with this system is, that you can not adjust anything and have to run a constant 91 octane just to make sure you do not have a Detonation. The ECM will catch the Detonation from the knock sensor and compensate for it by retarding the timing which in turn lose of HP till next start up.
If you like and don't mind the check engine light on once and awhile, you can do the same by just disconnecting the IAT wire harness which give the ECM a 0 resistance thinking it's -20 out side and turn the timing up and lengths the injector pules.
When i was running a Nitro in the Toy before i sold it, i had installed a 10K ohm Potentiometer which you can buy at radio shack for under $5.00 i believe, I just spliced it in to the IAC wire harness so if i wanted to play with the Nitro I'ld turn the resistor up making the engine think it's 185 degrees F and would ****** the timing so i would not hurt the engine. But if i wanted to get more timing i would just turn the knob to drop the resistance to get more time since the engine thinks it's -20 out side.
Hope this helps. Keep me posted if you need more info. Best thing is to do a dyno tune and you can change everything right down to the Shift points.

A new 02 sensor will come with new wires and connector. If not get back with me I think there is a repair kit for that problem.

maf is mass air flow sensor, it is on the air filter box, iat is intake air temp sensor, should be in the tube from the air filter box. don't know what atc and cts are sorry. best of luck
That is grey wire and grey with red wire.-------
The first one is only grey and second one is gery/red wire.

This will help.Thanks.Helpmech.
