Morning ya’ll long time lurker on this site. Got myself a 2020 eco with about 72000 now.
Few weeks ago i lost turbo boost on a grade and this code popped up, never came back and then suddenly it comes back on and off for the first few days.
Truck still runs fine and goes through regular regen cycles (able to monitor with scan gauge 2)
Im thinking because emissions diesels these days that one of the two egr valves has probably just been clogged of soot. Problem now is finding which one of the two. Anyone encounter this yet? Thanks.

Welcome not much help on your particular code, I would start out trying to clean the diffuser tube and the MAF sensor??? if it was mine simple and cheap start

Yeah ill probably go for the diffuser tube next, cleaned the map sensor and it was dirty but wasnt terrible i cleared the code and lets see if it comes back, my guess everything egr related just needs some love.

Welcome the forum.

Egr's need eliminated, not love. Unfortunately the EPA and our engineering community have no current solution to that mess. Good luck finding and fixing your problem.

Sensor B should be rear, post dpf. The odds of that clogging up seem small, but they are semi serviceable from what I've seen. The dealer will cover you if the wait doesn't bother you. I've also seen at least one person pop it, spray lube it, and put it back on. Pretty simple mechanism in there from what I saw.

@Reddiesel, why not take it to your dealer for a free diagnosis? Your engine is still under warranty. It's best to let them handle it.

Yeah maybe heading to the dealer might be a play, cali’s central valley is diesel trucks from eye to eye so might have some luck, if anything ill pop it off and see where it gets me thanks everyone.
