Ok since both codes are related to bank 1 and the mileage on this truck is up there, I would suspect an issue with the camshaft phaser for bank 1. The front of the engine would need to be disassembled to get to the phaser, these engines are known for timing chains failing and camshaft phasers failing. So this would be the area to check, replace the phasers and replace the timing chain.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
