Both codes indicate an issue with NOX sensor 1, bank one. IIRC Sensor 1 is in the exhaust before the DPF/SCR. Before replacing anything, I would first crawl under the truck and inspect the wiring harnesses for all sensors for damage.

It might be just the sensor, but also there is a reflash from Ford for the 2017-2019 trucks related to fake emission codes popping. My truck is currently throwing P0420 catalyst system efficiency below threshold bank 1. All sensors are functioning normally, but needs to go to Ford for the reflash and hopefully that fixes it. Fingers crossed.
