Looking for a sensor maintenance list. X15e Cummins.

Model year 2021 Pete 567. Engine manufacture date 2020. Family LCEXH0912XAZ.
Watching Ryan on youtube as well as Make Cents channel, I'd like to replace all of the emission sensors on the engine with new. Engine has 250k on it and all sensors are original. I don't want to wait for failure codes.
Mileage has been dropping lately.
Also what about the breather filter system?
Any info on the sensors would be appreciated.

 

Thank you. That gives me a list. I was not certain about the ccv. So the vgt actuator, is that a sooting issue or a temperature issue that causes failure?

 

Thanks. That's exactly the info I am looking for. I don't want to wait for codes, derates, and failures. I want to replace the ones that are pretty well known to need replacing as part of a maintenance program. I know I can carry a few of the super easy ones to replace in the tool box, but I think many of the sensors are like an oil change. Just has to be done.
