2019 troublecodes

[603Diesels]

Hey guys, I have a 2019 Raptor with 10k miles. I’ve done a injen cai, turbosmart diverter valve, borla catback and sct x4 can tune. Everything’s been great and running smoothly up until today. Went to hammer on it and popped up with the following codes. Good places to start looking? Thanks In advance.

P0299- underboost code
P04DB- crankcase ventilation disconnected
P061A- internal control module torque performance
U0422

Sounds like the diverter valve might be leaking. That will cause P0299 and can also cause P061A, since the PCM is not seeing the expected torque. The aftermarket calibration can cause P061A as well, but diagnose the underboost DTC first.

P04DB is related to crankcase pressure; make sure you reconnected all of the lines and they are securely latched. Even a small air leak can trigger that DTC. U0422 is a network related DTC and can be ignored for this concern.
