P2459 on My RAM 3500 Cummins 6.7 Dually // Diesel Particular Filter (DPF) Regeneration Frequency

[@DavidBrown-jt7yi]

I have a 2021 Limited 3500 HO Mega Cab and I have put HotShot secrets EDT since the 2nd fill up of the truck. If I don't have the EDT with me, our local Kum n GO fuel station has extreme diesel with all the additives in the fuel. It definitely cost more but well worth it. I have 30k miles on the truck and I've never had an error code, I never let the truck idle for long periods of time, ever. Thanks for the video.

[@AdventureRocks]

Thank you for the tip!

[@dougtodd416]

Please keep in mind that those big trucks that are idling, are mostly not owners of those rigs. They don’t care about the repairs. As a driver for 30 years, your tips are right in line. Well said.

[@AdventureRocks]

Great point, thank you

[@DanielMeyer-ls5ph]

After a hard pull, do not shutdown the engine until you have idled for about 3 minutes. Set the parking brake, hit the cruise control button and then the set button. The engine will increase the rpms to 1000 . Slow idle will load up the engine, washing the cylinder walls with fuel. Not cooling down the turbo will fry the oil in the turbo and fry the seals in the turbo causing eventual failure of the turbo?. 40 years of driving big rig.

[@electrified7309]

That's good to know, I have had a few times pulling my rv up and down the hills of Tennessee and when I was done I let it idle for about 5 minutes and the temperature went up, so I thought I was doing it wrong. Next time I will let it idle at 1000 rpm. Thanks again.

[@jatc8]

@@electrified7309 so if you idle the engine for 3 minutes at 1000 rpm, the turbo and oil cool off and that a good thing to do for the engine and turbo?

[@danielwagoner]

Good to know. I’m a new diesel owner and started using hot shots after reading lots of info in owners groups. I’m in the same boat as you with driving daily short trips and only towing the fifth wheel any one a month. Will be towing it for the first time this weekend and I’m really anxious to see the difference over my single rear wheel gas truck that I was using

[@AdventureRocks]

So far I'm in the clear between adjusting my habits and using the hot shot stuff. Always a learning experience that's for sure. Really it's a minor nuisance in the end to get such a solid towing experience.

[@miller6698]

Cummins does recommend a diesel additive, Power Service diesel clean. My truck has never gone 1 mile without additives. I was doing UBER with my 2015 Ram 2500 mega cab (yes Uber) and I picked up a Cummins engineer and he told me to always use Stanadyne Performance Formula, he acknowledged that Cummins recommended (which he said is fine) another brand but said Stanadyne was better. He also told me to get a bypass oil filter. I now have a 2020 Ram 3500 Dually. The increase in fuel economy makes the additive free, I buy in bulk and with fuel prices over $4.

[@AdventureRocks]

Good to know, thank you for sharing that helpful info.

[@OurRollingVoyageORV]

I started running additives after the first time my truck through a code. I started erasing the codes. But they kept coming back until at 92,000 ish, I cleaned my EGR sensor and cooler. Haven't seen it since. I'm at 98,000 + now. I full time RV so I pull my 5th wheel all of the time and I also use it as a daily driver. Just not that often. Great video, thanks.

Just to add. Remove the DEF injector and inspect for crystals blocking the screen. Mine was completely blocked by crystals resulting in DPF full, reduced power, see dealer. I knew what happened, the question was why? Removed crystals with a small flat screwdriver exposing the injector screen. This allowed the DEF fluid to do its job. End of problem.

[@stinson87]

I have a 2019 RAM Crew Cab LB HO Max. tow When towing, I use high idle if we are stopping for less than 10 minutes. I have switched between EDT and non, and I do see a difference, not in regards to maintenance but in regards to that 1 mpg. In my 100k miles I have never seen a P2459, and have only had one particulate sensor fail. for its 100k mile celebration it got the full hotshots secret treatment, with stiction eliminator in the oil, extreme diesel, and running 3oz EDT per tank rather than the 2oz for this oil interval. My truck only tows our fifth wheel, which is a mid profile 33ft at only 9k dry 11k loaded, But at the time I could not pass up the deal to get my truck, it was not selling due to RWD only so got a great price.

[@AdventureRocks]

Great tips, thank you. Sounds like a great truck.

[@21psd]

Unfortunately, if your daily driving doesn't allow your engine to get up to normal operating temp, it will not initiate the required regens. So, whether you like to or not, you do need to take frequent "joyrides" in order for the DPF to regen. Better yet, use a different vehicle (gasser) for short trips. Unless I'm driving across town, I leave my truck at home and drive our Jeep instead. And as you stated, excessive idling will compound the problem. My 21 Powerstroke is no different in that respect, I monitor my DPF percentage and once it reaches 100%, it will attempt to regen providing my engine and exhaust temps are right. This is the time I'll put some music on and take a little cruise to allow it to clean. As for the Hotshots EDT, I also use it religiously on every fillup mainly because of my CP4. But it alone doesn't solve your regen issues. Our diesels are happiest when we're working them hard while towing, etc.

[@MindFusion-ij1xl]

As stated above, it turned out the sensor measuring pressure differences across the DPF would not intiate regen unless I literally drove it like a drunk teenager for a mile, fast starts, floored, sudden stop, repeat twice, then the never-seen regen simply began- then drove it 60 miles highway, and the DPF filter stayed clean according to the gauge for it. 21 RAM 6.7

Hey, I have the same truck you have and got the is code 2 days ago. I use fuel ox on every fuel up and do not idle it while park. I also use platinum DEF.

The truck runs strong and no other codes or issues. I’m going to another dealer since I know this cleaning stuff is all BS and they just want money. Thank you for the video!

I started on a couple thousand kms to travel a couple days ago. Light came on about 100 kms out of town, I drive truck for a living so I am used to the lights coming on, and that's especially true when they are not on the highway. Anyways, light came on and I carried on with my trip, got to where I was going, and buddy cleared the code for me, luckily he was a engine builder that I was taking my 383 mopar engine too. That was about 800 kms into me trip, after cleared I drove all the way home and it hasn't come back on... I pretty much only use the truck for towing and travel so it was strange it came on, anyways, you are right our big trucks that are used in town always need regens, I run the highway and we never see our truck need a regen so this is something I know well... I have a little cheap ford escape for running around town and it has served me well 👍

[@petermandel2552]

If your Def usage starts going up clean your def injector. Its two 10 mm nuts to remove injector located on your exuast. White crystal buildup will mess with the spray pattern and is less efficient. Clean with warm water. Have the injector gasket available.

[@headdown1]

Hi there, I recently posted this in response to another KZbin video on this subject, but I thought you might find it interesting. I drive a 2017 Cummins Ram 3500 that I bought new. I now have about 130,000 miles on it. Half the year I am towing an RV, either 15,000 or 6500 lbs, and the other half of the year I run empty. I'm just about to change the CCV filter for the second time. Apparently it is not wise to let it go longer, and it causes other issues if neglected. The EGR valve clogging up sounds weird to me. I have never had an issue or message about mine. I have changed the differential fluids, 68RFE transmission fluid, and transfer case fluid twice so far. I use Peak Platinum DEF, after seeing a KZbin video of a guy showing the condition of his DEF injector which was already clogging at 10,000 miles using regular Peak DEF. The more he used the Platinum fluid, the less white deposits there were on the injector. I assume this applies to inside the SCR unit, where you don't want deposits building up. I use Diesel Kleen as a fuel additive. Until Diesel Kleen, Cummins wouldn't allow any fuel additives to be used without voiding the Cummins warranty. Cummins not only approves Diesel Kleen, they actually recommend using it. It also raises the centane of the fuel, and that supposedly means less soot produced, and less for the DPF to deal with and eventually get clogged with. I have an app on my iPhone that tells me that I average 881 miles between regens. I also monitor 5 EGT sensors with the same app that are already in place from the factory. Cooler running is not better, and produces soot for the DPF to deal with. Above 700 - 750 F, the DPF is not doing much, as there is not much soot being produced. If I am towing I am usually around 700 - 900F EGT, which is great. If I am not towing, I can't get the EGT up to even 700F, so I just know I am sending soot to the DPF. The Cummins likes to work and using it as a daily driver empty is not something I really like to do. Idling is bad too for running cool EGTs. Oil has always been changed at the dealer at the recommended 15,000 mile interval. I sent oil samples off to Blackstone Labs for analysis at 75,000, and again at 90,000 miles. Blackstone's report said the oil was in such good shape that I should extend the interval to 17,000 miles and test again. I won't bother, since the oil filter and fuel filters still need to be changed at 15,000 miles. But it did give me peace of mind that 15,000 mile intervals for oil changes on the Cummins 6.7 are not too long - at least in my case.

[@AdventureRocks]

Great point, thank you for the comment

[@robstatetx]

I have a local company that cleans DPF filters. My mechanic took it off, I dropped it off at their shop and they cut it in 2, cleaned it and put it back together. They do an air test before and after for flow and it went from 60% to over 90%. You lose quite a bit of flow just getting air through it. It was $500 to clean and $500 to take off and reinstall. They recommend about 80,000 miles to do it again. They did say the filter is a bit too small for this size engine and expected work load.

[@wildmanofthewynooch7028]

Your Idling is probably the number one factor. Using a good quality diesel adtivive like hot shots helps keep a consistent cetane level in the diesel not everywhere is top tier diesel.

Those kind of idles (at 5:30) could cause the new hydraulic lifter to prematurely wear out. Luckily mine was under warranty. They replaced cam, pushrods and lifters two times.

Howes seems to work well, especially when seasonal fuel is blended vs straight #1 or #2. Found better odds of finding non-blended fuel when filling at truck (pumps) in states where blended is available. Just replaced the fuel filter and water separator which showed discoloration vs previous changes where I fueled exclusively in a non-blended State more often. Also found my trucks run better, longer and more efficiently without the emissions… night and day difference, especially daily driving.

[@bjnorris2780]

You’re getting better fuel mpg.because it’s not going into regen as often. When the truck does a regen it uses more fuel. Went through the same thing with my 2022. Fuel additives help with the situation and lessen the regens but if you Replace the maf sensor you wont need the fuel additives as frequently Granted I do still run fuel additives every 4th fill up. I can now go between 700 to 900 miles between regens if I drive empty daily around a 30 minute trip. If I’m hooked up to a trailer and towing I only see a regen when the computer commands the truck do one at every 24 hrs. The maf sensor in my truck was reading the wrong air temp and causing the truck to slightly over fuel itself thus making it plug the dpf sooner. And the fuel additives kinda helped mask the issue by making the fuel burn cleaner. Up until I replaced the maf sensor my truck never made it past 275 miles between regens. The error code p2459 is set to come on if the truck goes into regen 3 times back to back and the miles between each one of those regens are 150 miles or less

Everything he said is basically true, but not always the real problem.

[@JFitness88]

I have a diesel Rubicon and run a scan gauge 3 in the OBD2 reader and monitor soot mass percentage and can see if I’m in a passive or active regen. If you turn your vehicle off during an active regen soot can start building up and stay around for awhile. I use my mini tazer to force parked regens to clear everything out. I think you can do the same with a Jscan device.

[@MindFusion-ij1xl]

Got something for you! I had no regen except once in 69k, then it regen and immediately said "Take to dealer". I instead drove 100 miles at 2500rpm. It went into regen BUT after a couple days, the DPF was half full. So, I researched. One told me to "Drive it like I stole it" (which I never do, always after fuel economy). Well, I DROVE IT HARD on city streets, inviting a ticket. Guess what? THE REGEN IMMEDIATELY SENSED THE INCREASED DIFFERENCE ACROSS THE DPF and initiated a regen. NO tool or meter would! So I drove it for 60 miles (at 2100rpm) and the DPF problem is SOLVED. Who would think you NEED to abuse the truck to keep its exhaust clean? But it worked- nothing else did! Edit: merely driving at 2400rpm for 50 miles recently DID NOT WORK but provoking the regen FIRST did work. 2021 RAM 6.7 with 69k.

I also been running Hot Shot Extreme LX4 once a month on fill ups and really can't tell anything different. in performance or mileage improvement. Only idle time I do is done few minutes before shutting off so oil in turbo can cool off a bit.

[@joebarry2641]

All the new diesel trucks do a passive regen cycle about every 800 miles for about 15 mins. Putting an Edge CTS monitor will show you when it’s doing this so you don’t shut your truck off mid cycle and start plugging the DPF!

[@AdventureRocks]

Thank you for the tip!

[@Mill72]

Misinformation…. Passive regens are when you have the temps in the exhaust system hot enough to clear the dpf without notice. Active regens are every 24hr running time regardless of soot load in the DPF or when you have enough back pressure difference with soot load. Like your short trips, etc will trigger a active regen. It takes about 20 miles to clear out. You have a DPF guage on your +19 trucks. It will dispaly when in active regen. You can shut the truck off without any issues. It will pick back up when the truck gets to operating temps to complete. Additive is not needed.

[@AdventureRocks]

Thank you for the comment and helpful suggestion. I have also heard aftermarket filters may throw a code...I guess the oil gets on sensor and throws off calibration.

[@robertpayne1153]

never ever let your truck idle more than 3-4 mins, cold start , press cruise and double press the set button, raising to 1100rpm has enough cylinder pressure to soot out....

[@DavidGonzalez-g3h]

Hey man thanks for video. I’m having same issue. Has it came back since?

[@AdventureRocks]

I actually sold the truck, but it's my understanding the current owner has not experienced same error code again. I believe in part it was due to improperly callibrated software that was basically giving up on the regen and throwing the error code. But, then my short trips and idling probably weren't helping. Regardless, once I cut out idling and did the Hotshot treatments, it never came back. At one point a RAM technician mentioned he thought a software update was on the way to fix the callibration issue.

[@kimsmith8991]

Hi there!! Thanks for the information. How did you Clear the Check Engine Light??? Do have to take it to Dealer??

[@AdventureRocks]

After cutting out the idling and doing the Hot Shot treatments (both the initial full treatment and every day treatment at fillups) it went away. I did hear through the grape vine that it is possible the code is at least part due to a software miscalibration. Anyway that's what worked for me, hope you can get it sorted out on yours.

Can you tell me what brand code reader you used on your Ram 3500?

[@AdventureRocks]

At the time of this video recording it was a super-cheap ($15) and generic bluetooth OBD II reader, but since then I've been using the Kingbolen stand alone unit featured in this video here: kzbin.info/www/bejne/gYXTdmmpYtCZgLs It's way more feature-packed and much less finicky compared to the bluetooth connection. Hope this helps.

[@dieseltechjoe]

So I have found most of these codes are caused by high oil levels. They need to be drained for 30 minutes. There's other stuff that can cause the code, boost leaks, poor maintenance, driving habits. But I deal with the code alot and about all the trucks have high oil levels. Let the truck sit for 15 minutes and check the oil level.

[@Leeryannavy]

Given your opinion at the end of the video about gas versus diesel, I just bought a new fifth wheel that is 16,000 pounds when it’s fully loaded or the GVWR. We only plan on traveling with it 2 to 3 times a year and the rest of the time it will be parked. Do you think a diesel Dooley is absolutely necessary?

[@AdventureRocks]

Do you happen to know the pin-weight on the fifth wheel either actual (from CAT scale) or manufacturer claimed pin-weight? If under 3K total when loaded/optioned fully, you probably can get away with single rear wheel (SRW) truck that has a payload/door sticker 3.7K min or higher. Some fifth wheel models/floorplans have unusually high pin-weights when loaded. For example my Jayco Pinnacle 37MDQS had an advertised pin-weight of about 3,200 lbs dry from Jayco. But, when optioned and fully loaded my actual pin-weight was 4,400 lbs and still within GVWR overall. So I absolutely needed a dually in my case due to the sheer pin-weight on the fifth wheel, though an SRW could pull it based on tow rating. Sometimes the advertised pin-weight on fifth wheels can go up 20-40% once optioned and loaded given the see-saw like configuration with a fifth wheel and truck. If you're not sure on loaded pin-weight for your specific model, sometimes groups on Facebook have fellow owners that share their sample weigh-ins from CAT scales to give you an idea. I'd say if you're anywhere close to 3K lbs pin-weight fully loaded/optioned you'll probably need a dually based on payload by the time you factor in hitch + passengers + tool box, etc. (~600-700 lbs allowance approximately). But, all that being said, if you're only towing short distances a few times a year and remaining stationary, that certainly can impact one's purchase decision ultimately. Hope this helps.

@@AdventureRocks great choice. That’s where I was leaning. I had a 2020 Ram 2500 6.4 pulling a 11k 36’ 5ver. Wasn’t happy pulling in hills and mpg/ fuel range was terrible. Went to a 2021 Ram 3500 LB diesel and absolutely loved it. Air suspension in the rear and 50 gal tank. Didnt know the 5ver Was there. Joy to drive but unfortunately sold everything to move to FL. Now wanting to get back into Rving and not wanting to deal with diesel maintenance and fuel costs I feel the 3/4 ton gasser is the best overall with a taller rear gear for a DD and occasional towing. The 3.73 in the Ram 6.4 was a dog maybe if I had the 4.10 it would have been ok. Good luck with your new ride.

@@anthonyp6124 I hear you, a lot in common. I am really impressed with the GM L8T with 10-sp so far. I'll be releasing a 1st tow video in about 10 days. I'm not towing super heavy, just in the 5-6K range with a travel trailer, but RPMs are extremely low while towing...very similar to diesel surprisingly. Just a night and day difference compared to the last gasser I had, a 2015 5.7 Hemi 1/2 ton.

[@tex_hd_diesel]

Idling is way worse than your 30 minute commute, assuming your commute is at highway speeds. I have a similar commute and have had zero issues. My 23 2500 has only actively regen'd on the 24 engine hour marks. That's 14K miles in. But I very rarely idle the truck (< 15% idle time). Also have never used additives in any of my trucks, except the rare occurrence of a winter trip from the southeast to the northeast during a time where we may not have switched over to winter blend yet down south. Agree with the other comments. If your 30 minute commute is at low speed, watch your DPF EVIC gauge, and don't shutdown during an active regen

[@AdventureRocks]

Great points. Thank you for sharing.

Sorry to hear. That's frustrating for sure.

[@howardsherman9461]

Have you had any other with your DPF system? I have been having very similar issues.

[@AdventureRocks]

After I started limiting idling and running the Hot Shot everyday additive, the issue went away. My understanding was that given my low mileage and shorter than ideal trips, the system really needed to be re-callibrated to allow for my less ideal driving habits and keep running to the regen instead of throwing that error. It basically would give up on the regen due to my shorter trips and then tell the system that the culprit was something in the DPF system rather than just my habits alone. I had heard that RAM was supposed to update the software, but that was through the grapevine.

[@howardsherman9461]

@@AdventureRocks We had one check engine light. And now the truck is running automatic regeneration every 50 miles. Something is not right. We drive about 20 miles each way, mostly on the highway. Not much towing.

[@AdventureRocks]

@@howardsherman9461 See if your code was the P2459...if so it could be same issue. It's like the callibration is off such that it throws a red flag if the regen isn't completed in X miles or hours as if something is wrong with the DPF system when in reality it is more the frequency/shortness of the trips. If you're able to do a long stretch to at least clear out the current regen that may be a temp fix. But for me it seemed like between the discontinuation of idling and the HotShot everyday at fill-ups...it caused DPF to regen less getting rid of it. I'm certainly no expert btw, so just sharing my experience. Hope that makes sense.

[@howardsherman9461]

Wanted to give you an update on my DPF situation. After months of frequent regens.....the truck would auto-regen every 50-75 miles....I finally brought the truck to Dodge. They recommended me to change the fuel filters and air filter to mopar before they would do anything(even though I had just changed them all 2000 miles before). That did nothing to change the situation. After 2 more appointments, they finally agreed to replace the DPF filter. Even after that, I am still experiencing the same frequent regens. I have another appointment tomorrow and Dodge has assigned an advisor to my case. I will keep you updated.

Yes, I think for me it was a combination of excessive idling and shorter hauls. Once I quit idling, combined with the Hotshot EDT, the code never came back. I also heard that RAM/Cummins may update the software to re-callibrate what throws the error code, so I think in reality it was being overly sensitive in some ways, but also I wasn't doing any favors with the shorter hauls and idling.
