Last August in Idaho, in the middle of a 8,000 mile road trip, I fired off my 2019 3.5 and ran about 2 miles. I had not blown it out in a while and the road was empty. Stop sign to a high speed wide open. As soon as I came off the throtle it thru several of the same codes.

Ran the codes and talked to Ford. Apparently my CAT was not at full operating temp when I gave it the boot. I cleared the codes and will make it a point to let that monster warm up a bit longer before house cleaning the motor. 4,000 more miles and no codes. Seem he was spot on.
