Had this problem about a year ago. Opened up the door panel and opened up connectors on window motor and door latch. Sprayed them out with contact cleaner, then packed them with dielectric grease. No problems since.
I've had very good results at AZP Installs in Kenilworth. They are mainly a Subaru Tuner shop, but have top of the line Hunter equipment. They have the Roadforce balancer, and the completely touchless mounting machine. Very nice to deal with, they actually care about cars, unlike your typical...
I had the same code and problem with my 2015 V6. Replaced the throttle body with a new Ford unit. Easy job, maybe 20 minutes. You can order on line at places like Tasca Ford at a discount. I think the new throttle body and gasket was about $65 dollars. Car runs great.
I don't understand why nobody was interested in it for the price you were asking for it. I'm in Staten Island. If you are of too far I will buy it from you. Thanks.

I had some creeking coming from the rear on mine. Turned out to be right side sway bar bushing was dry. Removed the clamp and used a silicone grease on the bushing. No more creek.
Up for sale is the Black Ford OEM GR3Z-8A224-AA Mustang running horse on the front grill. Bought this but never installed. My loss is your gain. $35 dollars shipped to 48 states.
There is a Ford service bulletin SSM47429 on the fix for this. It is a software issue, the BCMB body control module needs to be updated. Unfortunately, they will usually only do this for free under warranty. I don't know what a dealer will charge for doing this out of warranty. You can Google...
I also was disappointed with the lack of bass. I wound up using a Kenwood KSC-SW11 powered sub. It is small enough that I was able to mount it under the passenger seat. Added a nice amount of bass to round out the system. I believe it was about $200 dollars and an afternoon of labor to install.
