Personally, I just drive my truck. If it's regenerating when I get home I shut it off and it starts regenerating again in the morning when I leave. My '13 and '18 didn't have a DPF gauge and I never heard the engine sound different during a regen (mechanical valves) so I never knew when it was regenerating.

I chased regen issues on my '22 from around 15K miles to around 40K miles which ultimately were cured by a new DPF. Since getting a new DPF I have never seen the DPF gauge register anything. It does the 24 hour run-time regen that doesn't last very long.

I feel that if everything is working correctly the emission system works like mine does.

Keep in mind that I pull a trailer around 40% of the time.

How many miles are on your truck?

How many miles are on your truck?

As per photo at the end of last regen just over 11K but I have been noticed short 300-450 mile regens since 5K, also have seen oil growth so did a UOA 1396 miles after an oil change, it confirmed 1.5% fuel in oil, with just 4572 total miles on the engine... So yesterday I stopped by an asked dealer about the DPF going to zero as it seemed odd based on others I've had, I was told oh it did a passive regen, but later after a stop and restart I noticed the regen smell and sound, I checked the EVIC an see an auto regen message as in above photo, but I was just told it did a passive one before that is why I'm trying to figure out why it did an another regen about 17 miles after what I was told was a passive one that took my DPF to zero as you can see in my photos above..

 

Your truck is always doing a passive regen when driving. It's more effective with higher EGT's like you get when you have a load on. The gauge does not register anything when it's doing a passive regen hence the passive part...

Your short regen cycles and your gauge going up and down tells me something is not working correctly--could be in the engine (too much soot going into exhaust for some reason--plugged air filter, bad injector, etc...) or in the exhaust (like I said, my DPF was no good and kept telling the engine to regen but maybe you have a sensor that could be bad). I believe the voltages of the sensors and such are very low--I'm amazed anything works.

Like I said, my gauge never moves off zero since my problem is fixed. And I keep an eye on it.

1.5% fuel doesn't seem that high to me. My report said 6.0% (just looked it up). I was surprised it wasn't higher than that.

 

My second UOA fuel in oil went to >4.7% in just over 3347 miles, oil growth it another reason why I am tryin go stay on top of regens now and not wait until later when the engine sounds like a Hemi that needs a new cam & lifters or worse, and why I'm asking lots of questions trying to learn as my dealer is clueless, was told today when I asked why they don't talk to STAR they said if they ask them Q's about regens or oil growth they are told they need a case # & reason as to why they are wanting information so my only option is to ask for help in the forums

 

Just erase that screen from your mind....

 

Lousy advice

 

Today my truck DPF was at around 12% or so 21 miles after driving at Hey speeds it went to Zero, stopped, then drove 17 miles an stopped for a coffee, just after I had got back into the truck I noticed the truck sounded off, so got out to smell regen, ugg, low and behold I check EVIC and see auto regen so out the hwy I went, so the big question is, is it normal for the DPF to go to zero via what I can only guess a passive regen without me noticing it and then a short time later do a another regen as in maybe a 24 hr regen as I think I was close to that number? See attached photos below..

Like others have said just let it do its thing. My only recommendation would been to do a boost leak check. My 17 ran and drove complete fine as a matter boredom (If I am being honest) I did a boost leak test and found several pretty large leaks. I have since noticed my regens only occur because of time and no longer soot load.

 

That screen on my 21 3500 always shows 0 (zero). I will get the message saying performing a regen, but other than that its always at zero. Is it possible that sensor isn't working?

 

If the differential pressure sensor wasn’t working you would know, as it would trigger a DTC or multiple DTC’s. If your DPF gauge is constantly reading 0%, it’s most likely because you are operating the truck in a manner that is consistent with best practices. Your truck is working hard enough that it sees a good amount of passive regeneration regularly and the soot load is remaining at or near zero. You will still get the 24 hour regeneration cycles even if the gauge reads zero all the time. That’s absolutely the most ideal scenario for an emissions intact truck. The fewer active regeneration cycles the truck runs, the better. More regeneration leads to increased fuel dilution in the oil and takes life off of the DPF.

 

I’ve asked this on the HD forum but curious if anyone has noticed when an automatic regen starts and they are using cruise control that the engine makes a noticeable very quick change in operation, almost like a quick pause. I’ve only noticed it when I’m in cruise control and the truck initiates a regen. Thinking maybe it’s just in the programming when using cruise control.

 

Does the level of Def have any influence on the regen process? I have a 22 model that was shipped without a DPF sensor, I have about 25K on the truck and never had an issue with regen. The dealership did install the DPF sensor within the last 5K miles and everything seemed to be working just fine until last night. For the first time, I got a regen notice on the EVIC while driving (freeway). I went to the EVIC screen for DPF and it said it was 50% full. Then I got another EVIC notice that said the DPF was full (even though the DPF said it was at 50%) and that it needed dealer servicing and a message about power reduction. I kept watching the DPF sensor gauge, it went from 50% with a white color lighting on the % reading to a color of red % indication after 50% reading. Within 10 miles of driving (freeway) it went to 100%. I have just under 1/2 tank of DEF fluid, just curious if DEF level has any impact of how the truck regens. I will contact the dealership today, as this is a very strange anomaly as my truck has been running great with few issues other than the nagging entertainment system buzz that happens every once in a while. Anyone have a perspective on the sudden DPF warnings?

 

The amount of DEF in the tank has absolutely no bearing or effect on the regeneration process for the DPF. Although both systems are in the same exhaust pipe, they function independently. Since your truck is a 2022, I would highly recommend monitoring your regeneration cycles closely. From the data I’ve gathered on trucks with frequent regeneration issues, over 60% of them are 2022’s. If the gauge is showing that the DPF is filling that quickly, you either have a faulty differential pressure sensor, a failed or failing DPF, or an issue upstream that’s causing contamination or significant soot loading in the DPF. Regeneration issues on these trucks require a good bit of proper diagnostic work in order to determine the root cause (or causes). It’s also important to note that how the truck is operated can have a significant impact on the regeneration schedule as well. These trucks need regular highway driving for 20-30 minutes continuously or towing a few times a month in order to keep the DPF cleaned out and avoid repetitive regeneration.

 

Today my truck DPF was at around 12% or so 21 miles after driving at Hey speeds it went to Zero, stopped, then drove 17 miles an stopped for a coffee, just after I had got back into the truck I noticed the truck sounded off, so got out to smell regen, ugg, low and behold I check EVIC and see auto regen so out the hwy I went, so the big question is, is it normal for the DPF to go to zero via what I can only guess a passive regen without me noticing it and then a short time later do a another regen as in maybe a 24 hr regen as I think I was close to that number?

Sounds like Passive regen brought the soot load back to zero and then shortly after, you probably reached the 24 hour mark and the active regeneration kicked in. That’s perfectly normal operation. Contrary to what some will tell you, it’s worthwhile to monitor that screen regularly. That gauge is every bit as important as the rest of the gauges on the instrument cluster. If you make a note of the engine hours when that cycle completes, you can check to see if it’s a 24 hour regen by referencing the engine hours at the next one. Under ideal operation, you should only see regeneration at the 24 hour trigger point, rather than having multiple active regenerations triggered by soot loading.

 

My 16 will active regenerate 24-25 engine hours as has been mentioned. I monitor my soot load regularly via the ezlync3. Rarely does the truck ever get regen outside that parameter. However I mainly drive 30-40 min one way at 70-75 freeway.

Question for mbarber,

1-Dpf pressure never exceeds .5 psi, is this normal?
2- soot load never exceeds 1g, what does this equate to in percentage.
3-truck is stock outside of calibrated power software tune. Does the tune "clean up" the oem tune allowing better running leading to more efficient and active regens?

Thanks in advance,

Marc S

 

Not sure exactly what pressure reading you’re seeing with the “.5psi”. Might be the differential pressure between the inlet and outlet. If the truck is constantly reading 0% soot load then the differential pressure between inlet and outlet would be practically zero. So that might account for the .5 you’re seeing.
In terms of the soot load, i think the 45% on the cluster which triggers the regeneration cycle is roughly equivalent to 45 grams of soot. Not exactly sure though. Ram isn’t very good about getting that kind of information out. Depending on how the tune is designed and developed it may help decrease soot loading and be more efficient in its use of the fuel. Can’t say for sure without actually seeing data though.

 

The dealer did the YT443 update on mine and now I'm having regen issues. It seems I'm not the only one so I must assume Y43 is doing other things then just checking the new sensor.

 

If Y43 changed a parameter that ultimately caused regeneration issues, then every truck that received that update would experience the same thing. Which isn’t the case. My truck has had Y43 completed for months and have had zero issues. It’s more likely that they, the dealer, didn’t do something properly during the install of the sensor (like not securing it and causing an exhaust leak), or your issue is purely coincidental.

 

I was not at all surprised to see the DPF gauge started to go up today, the last time I had guessed it did so around 12.5 & 13 hours after a regen, now 13.40 hours after a 24 hr regen ( 444 miles, 80% of those miles were at hwy speeds, one drive was for 4 hr non stop at hwy speeds 60-70) the DPF started to go up and then up even more 11 miles late .... I'm a bit surprised that twice now the DPF gauge started to go up around 13 hours time frame, so the 64 billion $$$ question, is this some type of normal ecu programing? BTW 24 gallons of fuel in this tank is straight #2 diesel, the remaining fuel in the tank was B-5.

When I refill the tank here shortly I am going to try/add a full bottle of Archoil 6500-D Fuel system cleaner to see if it makes any difference like they claim it will, okay I know I'm dreaming but it can't hurt or so I hope

 

Update:

I was not at all surprised to see the DPG gauge started to go up today, the last time I had guessed it did so around 12.5 & 13 hours after a regen, now 13.40 hours after a 24 hr regen ( 444 miles, 80% of those miles were at hwy speeds, one drive was for 4 hr non stop at hwy speeds 60-70) the DPF started to go up and then up even more 11 miles late ....

Sounds exactly like what mine just started doing.

 

Seven months of zero soot load on the DPF gauge, all regens for those past seven months were all 24 hour cycles.

And now it’s starting to act weird again like it did back in May- June of last year. Most recent regen was only 14 hours and 502 miles. At 31 miles after the regen completed it registered 12.5% soot load:

51 miles later it’s at 25%

so it’s now at 25% after only about 80 miles. Whereas for the past seven months it wouldn’t register any soot at all for 7,000 miles. Same fuel station, same driver, same routes, same speeds, same fluids and filters, ….literally every factor the same except the date.

 

That’s normal when gauge comes 45% it will start regen some case 46 or 47 driving a lot in my eyes normal. I’m driving a year minimum 110k miles between 130k miles. You think it will be same as when you purchased your truck that date. No it’s not working like that just drive truck littl longer no too short distances even short distances don’t turn off also if its doing regen wait till fini every 24 hrs after do it passive regen parked your car wait 60 minutes between 75 minutes than it will start regen you will see.

Something to ponder. Summer is here.

 

This afternoon I emptied my 275 gallon water tote as I have too have more room to haul some items to the dump and then move some stuff for my daughter, so for the next week it will be driven without the 2300 payload in bed, it will give me a chance to see if it makes a difference to the DPF than it has recently with the weight in bed, it will also be running on the same fuel additive so we will see what changes or not....

 

Any update? Curious to see if the additive is working without the weight in the bed.

 

So, when y'all say that the dealer didn't install the sensor... you're talking about the passenger side bung that's just before the rear axle right? mine still has the plug in it, not a sensor, and they marked the Y43 recall installed, flashed, and done. After that I noticed on stock airbox/filter/intercooler piping it would regen very often... (I knew I should have made a log of it... oh well: coulda shoulda woulda...).

I drank the koolaid/bought the snake oil and installed the Banks "performance kit" (cold air intake, monster ram with egr valve, grid heater change plate, intercooler piping, idash monitor, pedal monster) on my truck. I noticed something VERY weird... essentially the regens STOPPED completely except for the time based. DPF gauge never went up really... sometimes it would tick up one or two if I was hotrod'ing around... but 20-30 mile trip down the interstate and it'd clear out.

WELLLLLLLLLL, it got cool and then hot and cool outside, the truck saw that there was an increased amount of EGR gas coming through, threw a code for it... I can't stand lights on the dash... so I'd reset it... just kept coming back, looked it over no leaks anywhere, nothing wrong mechanically. Called banks, they admitted that their cold air intake had been causing that code... offered to either return it for full price, or I could wait and they'd let me know when the "official fix" is out for it. I returned it and put back in my factory airbox/filter and noticed my DPF gauge was going up FAST. Started to monitor the DPF trigger % on the idash, and boy... it'd go up 12-18% every time I'd get in the truck to go run an errand... no matter 30 mile trip or 3 mile trip.

Two weeks later noticed I was having a boost leak issue... three tries on my own to chase down and fix the boost leaks, a shop trip, and finally getting pissed and just putting stock intercooler piping back on today... that fixed and sealed the system finally. Noticed the DPF trigger % only goes up ~1-5% per trip. I think I'm on the trail to "undoing my mess-up", but any help would be appreciated.

 

So, when y'all say that the dealer didn't install the sensor... you're talking about the passenger side bung that's just before the rear axle right? mine still has the plug in it, not a sensor, and they marked the Y43 recall installed, flashed, and done.

testing testing mic check 1 2?

also, computer SAYS it's running about 10-12 hours between regens, but only 160-200 miles during those hours. that normal?

 

An Update from this afternoon.:

Well on my way to get my bed liner repaired the truck went into its 24 hr regen, sooner than I thought.. I still stopped to get my liner repaired and then headed out to the hwy to finish regen, the regen took a total of about 16.5 miles I was shocked at how fast it did this regen as the last time I did a 24 hr regen I was driving up and down some nice hills towards the pass at 55-60 mph and it took about 25 miles to do that 24 regen. Oh I also had the 2300 lbs weight in the bed at that time. The first photo was taken about 2 miles after regens started, had to wait to get photo as i had a police car next to me. When I compare the 2, 24 regens, it seems like the Archoil helped with this regen ( compared to the one before) and I have no weight in bed this time, it only took only 16.5 miles ( approx. 8 miles of city stop go 25-40 mph) with a 40 minutes stop in between regen start and it finished 8.4 miles later with speeds between 50-61 mph... Being I have to wait for bedliner patch to cure I can't put tote back in the bed so we will see how it goes over the next 100 miles

 

I walked past it the other day at my buddies in his driveway to get something out of the bed, could hear my truck making electrical whine/beeping from the far rear of the truck after it had been shut off for almost 2 hours… I’ve been wondering if my truck has been staying alive after I turn it off, get out, and walk away for a while.

When I look at the total hours vs miles, the idling hours are ~1/4 of the total hours on the truck and the average speed was about 28mph iirc… I can get the hours/mileage in a bit when I go to work.

 

As for the Y43 they just have just marked the recall done because there is deeeefinitely a plug in the exhaust still. 🤦🏻‍♂️

makes me wonder if they did the other two recalls(grid heater relay and trans dipstick) or just booted it out the door without any work.

 

I'm not crazy right? just walked out to the truck to take that picture... reached in past the passenger rear tire facing forward...

 

Not at all crazy.
Someone is lying to you. It should look like this:

 

If you're not getting a check engine light they did not update the software either. My dealer did the software but not the sensor. Immediate check engine light.

Seems to me the dealer is scamming Stellantis.

 

Hmmm, not sure if I should go in and yell at them to put the sensor on or not at this point...

guess I should look into the other two recalls fully and check if they were ACTUALLY done too...

 

An update, so far have used 3/4 of the Archoil treated tank, the DPF gauge is still at zero since 24 hr regen even though it's only gone 142.9 miles in 5 hours 17 minutes with approx. 40 of the miles were hwy driving at speeds 55-65 MPH with one short heavy footed burst 55 to 80 MPH today due to jack @ass. Oh the weight has not yet been put back into the bed so I'm surprised with all the stop and go its seen the DPF did not go up ... Also when I do refuel I will then start using the Arch oil 6500 fuel additive so we can see if it does any good or not.....

 

I’m about to buy some and try it. I’ll let you know if I see the same results.

 

I hope that you two will see some improvement in regens, I would hate to think this is a fluke, but then one can never tell now days with these trucks, I will also go back to refuel at the same stupid station that claimed to not be selling Bio diesel even though it's a state mandate that all regular diesel sold has to contain a minimum of 5% Bio. Also by the time I refuel the truck since the 24 regen it will have seen 2 short trips of a max of 5 miles round trip, truck will be shut off two times on a trip with one of the trips later today....

 

dumped it in to the tank tonight and filled with fresh fuel. I’m 97% of the way to a regen, so it’ll regen out tomorrow and then we’ll see how it does. I’m not holding my breathe.

 

I really hope you will see some improvement in regens, being you drive more than I do and for longer trips would hope it helps clean up & out crap in the DPF..... Oh the trip I took to the store & coffee shop yesterday was a total of 4.5 miles, it was shut off twice( do not like to sit in line for coffee or food so shut it off often and walk up thus my truck sees lot of start ups), still no rise in DPF gauge...
