2014 RAM Cummins derated to 5 MPH

Diagnostic approach of a DEF pump issue and repair.

[@normbal]

Suffering through this recently. Bad bottle of Maomart DEF dated 6-30-2022. Dealer in Columbia TN “fixed” for $607. Drained tank, replaced o-ring, filled tank. 370 miles later, halfway home, DEF, check engine, 150 miles to limp home mode. Dealership in Abingdon, VA showed where SVC tech in TN got DEF on pump contacts which corroded contacts. Cleaned up, plugged up, filled up and I was on my way, sweating bullets until I got within 150 miles of home. I normally use about 2.5 gallons DEF in maybe 5000 to 7500 miles depending on what I’m towing. TN to VA used a quarter tank, refilled, next 380 miles the DEF needle barely budged off full. what a messed up system. This happens again I’m buying a delete kit.

Man I’m glad I found your channel!

[@dieseltalkwithtonysalas8725]

Thanks a lot!

[@anthonykontos7931]

@@dieseltalkwithtonysalas8725ust found your channel this is interesting to know I just replaced my def injector and still have this code U029E. I just picked up A code reader and erased it but still have the message on the dash saying “Service def system see dealer.” How long before the message will go away after deleting the code ?

In the middle of nowhere in Urah, my truck says service def. A few minutes later it went to count down. Later, I had 20 miles till it went into limp mode. Stopped and pulled batterie cables. Made it to a Dodge dealership. They came back an hour later and they could not find anything wrong. Drove home 500 miles away. No problem. Twice this has happened to me. Ruined my vacation. Any lawsuits happening with this bullshit. No problems till I paid my truck off.

[@dieseltalkwithtonysalas8725]

Definitely an intermittent concern. When you reset it by disconnecting the batteries you cleared the codes. Buy a cheap auto parts special code reader and next time it happens before you disconnect batteries check for codes first. If your truck has the recall don’t get it updated. Issues with the update

[@johnoshea5230]

Well done ,it feels good when it goes right.I have an 09 that`s going into the 5 mile an hour mode ,i just bought the truck and i`m a bit concerned about if it can be fixed and the cost.

[@dieseltalkwithtonysalas8725]

Of course it can be fixed ! Just need the right tools and info! Hope you get it fixed!

[@Peterswarahed]

So did you fix the problem and the cost ? Thinking of getting one soon.

[@michaelpacheco75]

Informative video thank you

[@dieseltalkwithtonysalas8725]

Appreciate your input! Glad it helped!

I had the P208a code come up on my 2017 ram with 197k on it. I tried to siphon some def to see what it looks like. All I got was a gel like crap that wouldn't even suck through the hose. Pulled the tank and it was full of this gell. I can't swear in court that I didn't have a brain fart and add either Lucas deep clean or Power service to the def tank instead of the diesel tank. To see what would happen I left some def in the jug and added both to see if it gelled. Nothing after a week. All seems well so far. Trucks running fine. Any ideas?

[@jeovanyarteaga5906]

Hi I have a problem with 2014 Ram 6.7 With only the P1C70 and I can’t erase the code..and still have a 5MPH Max speed service DEF SYSTEM ON THE DASH ..I replaced a def injector .. And the def pump I have only 14.6 psi

[@peterkosewski]

Got 150 mile message pulling sleds north. HERE WE GO! So far injector nozzle tests bad on bench. Can't get in to dealer around me for a month minimum

[@dieseltalkwithtonysalas8725]

What would help is the code it setting. You do have a check engine light on?

[@troyandeviegray9736]

Having same issues does it really drop you to 5mph ?

[@dieseltalkwithtonysalas8725]

Did I ever reply ? I am sorry! But yes it will not go over 5 MPH

[@34mhair]

My 2014 2500 Ram is in countdown with 15 miles to limp mode and has zero codes thrown. I took it to a local Diesel Performance shop and they hooked the computer up to it as well and no codes and could not clear the countdown. The shop forced a regen and still nothing. Any thoughts or help would be appreciated.

[@dieseltalkwithtonysalas8725]

Is the NOX light or Message on? Email me a pic of the dash with engine running at [e-mail]

[@swiftyplayz8247]

I have the same code (P208A) come up on my 2013 2500. So is there a good chance that I have a bad pump as well or could it be the wiring?

[@dieseltalkwithtonysalas8725]

Most likely, it is a common problem, clear the code if it immediately comes back, it can be.

[@phillipgarrow2297]

My ford F250 6.7 started acting up once it got cold to much idle time it overloaded the exhaust filter the truck set all summer at the dealership I bought it at the in early November it gets cold in Michigan it warned me it was going to limit speed to 50 miles a hour in 10 miles it cleared its self and never did it again I've had a lot of diesel trucks over the years it's to bad they put all the emissions on them I still have a 2000 F350 4wd drw powerstroke I not getting rid of it now it's a plow truck

[@ronhoffman6555]

What kind of tool are you using to plug in the truck for the codes and ifo?

[@dieseltalkwithtonysalas8725]

I have a few scan tools, but on RAM/Dodge I use my Snap On Zeus scan tool. I am trying out the JALTest scan tool now.

[@dieseltalkwithtonysalas8725]

Geez it’s a bad one. I go after the relay code since you have the U code. You a tech? Have service info?

[@jeleelbellot4351]

What exactly did you do that clear the SERVICE DEF SYSTEM?

[@dieseltalkwithtonysalas8725]

Need to scan and see what error code it has to have a direction

[@danasmith376]

What makes pump run after taking key out for like 20 seconds?

[@dieseltalkwithtonysalas8725]

If the pump runs with key off is that it’s reverse “pumping” Meaning the system empties itself to ensure there is no DEF in the line to the doser when truck is shut off. Imagine DEF freezing on a cold night in the line. So this ensures no DEF left in line. There is a reverting valve that allows the pump to flow one direction but then reverts flow to the opposite direction.

[@danasmith376]

Is that normal? Will it hurt anything?

[@pocoyoarriaga]

My truck is on limp mode Diesel exhaust fluid line pressure shows 601 kpa, what that means?

[@dieseltalkwithtonysalas8725]

If in limp mode you should have a code or codes set. Need that info

[@pocoyoarriaga]

Yes code is P1c70. 2014 2500 cummins

Tengo una ram 2016 motor Cummins ino medeja correr maske a 8 kilometros ocupa borrar cosigo def

[@davidringer6775]

At the end of the video. U can clearly see the check engine light is back on. And u never scrolled through the vehicle messages. Where the message for 5mph max is displayed

[@dieseltalkwithtonysalas8725]

That is correct caught that after I shot the video. Nox sensor 2 to was the issue with that and truck was good.

[@dieseltalkwithtonysalas8725]

CORRECTION! I got trucks messed up! The reason why the check engine light is on is because the engine is off! Notice no RPM. Check engine light comes on as a bulb check with key on engine off! No why in the heck you trying to mess me up?!

[@chrischapman276]

Just subscribed to you. Is there a way I could email you for some info on my 2014 3500 that I'm working on? I've recently removed the exhaust and replaced with a delete pipe along with removed the DEF system to do a total delete. But, after doing some work on it by cleaning up the def system lines and tank along with the exhaust filter that stated it was 100% full I'm wondering if the work I've done may have been enough to repair the problems. Even though I've installed the pipe, finding the tuner is like pulling teeth with the price of them in the thousands$$$. If possible to email to keep these comments to a minimum, I'd appreciate it if you could/would.

[@dieseltalkwithtonysalas8725]

[e-mail] But! You deleted the truck without a tuner? Or are the sensors and def injector still plugged in?

[@chrischapman276]

@@dieseltalkwithtonysalas8725 New straight pipe. DEF is removed. Only thing left is to do the tune. (And disconnect the EGR) I had a problem with the DEF faulting on me consistantly being the last one the final straw. My wife filled up the truck with some 87 octane, causing the filter to clog, possibly. Regardless it stated it was 100% full. That's when I purchased the pipe and removed/replaced it. Had a Duramax before and regret going Mopar.

[@earlshop8312]

I have a 2017 ram 3500 6.7 cummins how do I disconnect the DEF from The exhaust filter

[@dieseltalkwithtonysalas8725]

Not sure what you are asking me can you clarify?

[@walterk1221]

DEF doesn't "connect" to the DPF... it is injected into the SCR.

The only redeeming quality of ram was the Cummins and they dekcuf that all up with $20k worth of emissions junk that give it the same mileage and acceleration as an old Buick. Having said that, I’ll be selling this piece of tihs soon.

[@TheMinnow101]

typical YT video. 15 minutes of blather followed by 1 minute of actually working on the problem with video edited the moment a problem is encountered. Then video cuts to repair completed. Waste of time.

Gotta love emission junk malfunctions.
