Without any other information on how the truck is running and symptoms and what you have done i will throw 2 cents into the diagnosis........lalso full model and serial number are a help but here it goes.....

522712-4 is for Accel pedal sensor A OUt of range low(OORL).....did you inplug the accel pedal with key on...???

2023-12 is Canbus error as stated

522655-1 is short term fuel lean condition
522592-1 is EPR(Electronic Pressure Regulator) Pressure low
These two are related and more than likely the initial codes generated

91-2 is for TPS(Throttle position sensor)......was this also unplugged with key on during your diagnosis....????

Your codes are all over the place. Check the Canbus resistance, you have a couple of can errors, these can cause a lot of erratic codes.
