This is interesting. I have been struggling with frequent regens and it does feel like it has something to do with air intake. It's hard to describe why other than the DPF % seems to shoot up either when the engine is in low rpms and trying to get up to speed, or when I really step on it. Interestingly it mostly comes when the truck is cold. I can have my DPF shoot up from 12% to 70% in 10 miles, and then have it drop 1% over the next 10 miles.....all with the same driving habits and at highway speeds. Maybe it seems normal for truck temps to impact, but it shouldn't drive that much of an increase that quickly in my opinion. It's almost worth the $ just to give this a shot. Already changed air filter, oil filter, and fuel filters trying to fix.

What was reason chose the 60261 vs the 20260? Thanks
Also curious about this....I couldn't tell the difference between the two options other than how they connect and price?
On my star case regen every40 miles, Ram has Mass Airflow Sensor coming to be changed out. No idea of which it is as has been in shop for 3 weeks. Part was supposed to be there last Tuesday now looking at Wednesday before Thanksgiving. Probably trade in if not there. Can't keep it in shop all the time.

Here’s what I got from AG when I emailed them today with my question. They said if heavy towing go with the 20260 but in my case of only towing a 10k trailer 4-6 times a year the 60261 would be fine.
They both offer up to 90 horsepower increase and 1-3mpg in fuel savings. The 60261 is a fuel rail module. So, it’s making the truck think it’s not producing enough fuel pressure, so the truck compensates or “steps up” for how much it thinks its low.
The 20260 is an injector module so it’s controlling the injector pulse width, holding the injectors open a bit longer so it can add more fuel; therefore, more power.
I would say you would be fine with the 60261, plus it’s easier to install.

Price when it describes it does the same thing.

Mines been in twice. Now they wanna change the MAFS and said RAM has a problem since the recall. My question is why does it NEVER move off 0 when towing 20K and there saying thats a safety feature....?????????? Not much hope then that anything else they say is correct

It doesn’t move off of zero because it is doing passive regens. That’s when the exhaust temperature is high enough for it to regen without extra fuel being injected into the exhaust via a late injection of fuel on the exhaust stroke. It can do a passive regen empty but it (mine) will only do it above 75 mph and du a long drive. Does better 80-85 mph.

Yeh that’s what I’ve been told and always thought but there telling me it says at 0 because that’s a safety factor…. Lmao

That really doesn’t surprise me with some of the other crap they come up with. If they don’t know what or why that is, just say so. They are just showing how little they know about these trucks.

Looks like there are two MAF part numbers (68334657AA and 68444077AA) listed when I checked a few Mopar parts sites. RockAuto shows the 657AA part under the catalog for MAF. The 077AA can be found using direct search.
What appears to be the later part number (68444077AA) is the one backordered.

Knowledge of these systems and their functions is absolutely critical to being able to properly diagnose and repair them. Simply following a diagnostic tree doesn’t always work. You’ll find that the vast majority of the dealerships that sell these trucks have limited or no understanding of how they actually function. If you’re lucky enough to find a good and knowledgeable dealer / technician, stay with them. They’re worth their weight in gold.

I’m confused as to why one is listed in one schematic for the air filter system and one is listed in the schematic for the EGR system. Is that supposed to be an update version for the old one ?

The sensor on the filter is MAF. The one associated with EGR is MAP.

I’m confused as well. Could be misinformation just copied over and over or could be a newer part. The sensor in the EGR diagram looks like the MAF sensor.
The exhaust manifold pressure sensor is 68444078AA.

That is Exactly the way it happened on my truck. Everything was fine with no active regins (only passive) the first 18k miles, never seeing the DPF guage register anything. Then one day my DPF guage started to rise. Over the course of a couple days it got to 45% and started a regin. Since that time it was just a cycle of 2-300 miles to the next regin. Something Changed Period. Thinking back, the only thing that I started doing differently was fueling at the terminal where my farm fuel delivery's come from. They also have pumps out front where you can pump on site in which I did to fuel my truck. For my farm I have always ordered bio-diesel so I was asking them one day if their pumps out front also contained bio-diesel and I was told no, that they used Power Service in their fuel in order to help with lubricity. I am now going to switch back to the fuel that I was using before and see if my issue clears up.

You could prolly goto McDonalds and run straight french fry grease without an issue these emissions' are that messed up. I wish i could go 2-300 miles. Mine goes 25 to 75 since the recall. Mines been at the dealer twice in the last 2000 miles with no end in sight. Talked to dealer on Wed and was told Ram has a huge problem with these trucks that all the dealers are seeing this and just stabbing at changing the MAFS because Rams radio silent about it but also there back ordered with no time frame as to when they will be available. Talked to an independent shop as well who said more than likely they will never get this fixed correctly. WIth it being a small percentage of their overall sales and given the time frame with supply chain shortages and all they will prolly let it run its course and the owners will eventually go away. He also said it a shame for cummins because its a great engine other than the Ram shipping crate they come in
To me it seems like Ram dealers should have been told and inform potential buyers that they are selling these without a vital component installed and will need to be recalled, I wouldn't have bought knowing that. This seems to me to be grounds for a civil lawsuit against Steallantis.
Dealers were indeed told to inform their customers that the particulate matter sensor was not installed, and that it would need to be brought back for a recall. This is the document that every buyer was supposed to be given at the time of purchase:
I signed one the day my 2022 was delivered. That was 11/30/21.
Yet again, the particulate matter sensor is not the cause of frequent regeneration cycles, nor is it the fix.

Interesting cause I don't have that form
