Cause
Truck only has 5000 miles on it. Ford has replaced 4 injectors and the PCM already at 2500 miles. CYL 5 injector is original yet but 7 they replaced. When the Truck is cold all injectors show the same resistance reading. Once the truck is warmed up 5 and 7 resistance goes high. others all stay the same. I tested at the PCM and directly at the injector and got the same high reading. Truck runs perfect even after it sets those codes.

Correction
Replaced two new injectors in and problem was solved.
