All that is available from the Ford Workshop Manual and the Electrical Schematics. There are lots of threads here that suggest different ways of getting those items.

Default ambient air temp sensor reset

Greetings My new to me 2015 F150 XLT is not responding to all the suggestions on how to reset the sensor,,SO,,I bought a new sensor at Oreilly's. I bought the OEM at $30 instead of the china model at $16 thinking it be better. Well, So far I have tried a every method to reset with none working,,!! What is VERY puzzling is the wiring at the sensor has only a green wire and a White wire. YET at the big connector where it plugs into ,,that connector has 6 (SIX) wires,,,!!! Did maybe the PO connect these WRONG,,,?? HELP,,!!!

The AAT sensor only has two wires. What makes you think the AAT isn't working? Are you getting a DTC?

There is no reset possible.
The Ambient outside Temp sensor is direct wired to the Computer.
The Program uses it to compare with the Map T Sensor for a reasonable agreement on cold and Hot re-starts vs Cylinder Head Temp value.
This sets the fuel Injection amount and Ignition Timing to fit the circumstance for starting.
The reading you see is for your general convenances.
Good luck.

I hate to tell you this but there is definitely a reset for the AAT fords own workshop manual literally tells you to reset the sensor after replacing it by pressing the recirculation button and ac button at the same time then pressing the ac button again within 2 seconds
