I have a 2001 7.3 with the banks big wheel turbo, banks big head actuator with banks monster exhaust. 3 days ago i was driving up a small hill that i usually fly up in 5th gear and was forced to downshift to 3rd due to my truck losing all power, the engine revs up but there is absolutely no power. I changed the CPS and checked to see that the turbo is spinning. I ran a diagnostic test and found these codes, can anyone help me? PLEASE !

CODES: P0475 Exhaust pressure control valve
P0476 Exhaust pressure control valve performance
P0541 Intake air heater circuit low
