It may take a little while to get everything back to normal. But I would monitor and see what happens in a week. If it continues, you’ll want to have your truck checked out by a competent dealership as yours is likely experiencing an independent issue. What error code did you mean by “particulator code” ?
P2459 Diesel Particulator Filter Regeneration Frequency
I would recommend taking it in and having it checked out by a dealer that’s competent with these trucks. There have been an increasing number of 2022 trucks with that same DTC. I have a contact who is an extremely experienced Ram diesel tech. He was telling me the other day he’s seen several of these same issues at his location. He suspects that there may have been a change in the media used in the DPF itself and they’re going to pull one apart and look it over. In any case you’d want this issue noted in case it is reoccurring or leads to further action. I would try and perform a parked regeneration, then have you run the truck and see what happens. You need a baseline of back pressure across the DPF when the system is cleaned out, then drive it as you normally would. If the truck continues to trip into constant regeneration then your problem lies elsewhere. Could be something as simple as a boost leak in the charge air system, or more complex like a faulty injector at the engine or malfunctioning differential pressure sensor in the DPF itself. My friend also mentioned that Ram’s current diagnostic procedure for addressing this issue is lackluster at best, and doesn’t follow the best practice for finding the problem. There are so many different avenues that can lead to a regeneration frequency problem that it isn’t an easy one for unfamiliar techs to try and diagnose and most dealerships ultimately end up tossing parts at it in random orders and never truly get it right.
You have to assume that they're going to install the right one, no? If they don't it's their problem. I was out $50 bucks because my truck didn't like the one that I installed. Plus all of the time screwing around trying to figure out which one will work.
I would say you’re placing too much faith in the dealer. I’d venture to say the vast majority of the dealerships are going to look at the parts catalog and install the 68517554AA in the truck because that’s what their system tells them to do. Most aren’t going to read the “tech tip” that says to actually use the 53034051AB. And even if they do, their network will likely show the correct filter is on extended backorder. So you’ll either get the wrong mopar filter, or you’ll get a cheap knock off aftermarket like a Wix which can also easily cause issues. Your best bet is to order the Fleetguard AF27684 yourself from a reputable supplier like Genos Garage or your local Cummins engine shop, and put that in your truck yourself. The fleetguard AF27684 and the mopar 53034051AB are identical and are the only two filters you should be running in these trucks. Period. Your mileage may vary wildly with aftermarket ones. There have been a plethora of issues with these trucks using anything but those two filters.
If that’s the case, they installed the wrong one from the factory. This air filter works just fine in a hemi. It was factory installed and been fine for 30k miles.
Per the Tech bulletin:
I see that. Must’ve been published after my truck was built. I have a replacement on order and I’m putting the same one in it that it came with.
Given the 10% fuel dilution in your engine oil, I would suggest doing some diagnostics and testing of the injectors. You may have one or more malfunctioning. Keep in mind that the injectors can be the cause of the Regen frequency issue from two different angles. If they’re overfueling, then you’re going to get more unburned hydrocarbons passed downstream in to the DOC / DPF which will cause a faster than normal increase in soot loading. At the same time, when the truck sees the DPF filling and engages a soot load based active regeneration cycle, those same overfueling injector(s) are now responsible for dosing fuel in during the exhaust stroke in order to drive up DPF temperatures and burn out the soot. This is a double whammy when it comes to saturation of fuel in the engine oil, and if left unchecked could result in a fairly aggressive wearing of the rotating components and the hydraulic valve train. Cummins made a huge mistake in choosing to use the engine injectors for the regeneration process. So much so that I feel that may be the true Achilles heal of these engines. Far more so than hydraulic lifters.
I had a similar issue with my last truck (not a RAM) the dealer kept throwing parts at it and the truck was at the dealer for extended amounts of time. It sounds like you cant smog it which means you cant renew the registration. I got tired of the whole situation on mine and did a lemon law on it. CA has the best lemon laws in the country.
I’m sure you’re right that’s common when old part numbers are superceded. Had my fingers crossed that I would get an AB filter.
Pics comparing.
The 53034051AB is a higher cost at some places. I bought mine at Genos $37 for either but Rock Auto lists both filters for the 2022 6.7 Cummins the AA for $40 and the AB for $54. Who did you order from?
I agree completely. I think the AB is a better / sturdier filter all the way around. Which would stand to reason why it’s used specifically for the diesel. These Cummins trucks demand a lot of air. It’s not uncommon to see a lot of aftermarket inferior filters getting collapsed. If the build quality isn’t there, they won’t hold up. This was posted in a different post / thread a while back:
Amazon. I reached out to them as there was a $7 difference between the part I ordered and the part I received. They issued me a $15 promo code for my next order and that was satisfactory to me.
