Service def see dealer

[Glenn ronquille]

I have a 2018 ram 2500 6.7 44000 miles went to the truck stop and filled up with diesel and def both tanks were between empty and a quarter tank when I left the truck stop I got the message but no count down to Limp mode has anyone else ever have this problem and how to fix thanks

 

[sag2]

Once you fill the tank the ECM runs the monitor to make sure everything is working properly. The code is usually bad DEF but that is not usually the case. More often than not its a sensor or crystallize DEF on injector or lines.

 

[Glenn ronquille]

Thanks I’m bringing it to the dealer Monday just didn’t want to travel to far and get that count down and get stranded

 

[gsbrockman]

I’ll bet that message will go away on it’s own after a couple or so key cycles....

 

[Glenn ronquille]

I hope you a right because I hate dealing with the dealership

Was the truck running or off when you refilled the DEF?

One time.....I received that message on my 2014 RAM 3500 when I refilled the DEF with the truck running...

 

[Glenn ronquille]

The truck was off and the two codes it’s giving me is
P207f
P203f
P207f is reductant quality performance
P203f is reductant level low
If I drain the tank and put some peak do you think it will clear up the check engine light

 

[gsbrockman]

I can say with a high degree of confidence that your truckstop DEF is not the issue.

You may have coincidentally a DEF pump in the early stages of failing.

 

[sag2]

Are the codes active or stored? Are you sure the DEF tank is full? Sure you didn't get diesel in the DEF tank?
Don't let them throw out the DEF in the tank unless they have checked the concentration with a refractometer.

I actually purchased a refractometer and carry it with me just for this reason. I'm not sure if I should sample periodically, but at least if on the road, I can diagnose and possibly remedy a DEF problem.

Cheers, Ron

 

[sag2]

Interesting I was looking at the diagnostics for the code. It says "is the DEF between 28 and 47"? In class they always said it had to be exactly 32.5 or it would cause problems. It would appear it's OK with higher concentration but not lower.

 

[jelag]

I've had the code twice after months and months of issues after one of the major recalls.... in my case I pulled the DEF injector and found it caked with crystals... I first knocked off the crystals and than flushed it clean.... reinstalled the injector and cleared the code and its been good now for 15K miles...
I had trouble getting the gasket from the dealer... they had issues finding the correct part number and didn't have it on the shelf.... like... have the tech's ever pulled one of these injectors and cleaned it....

 

[EDankievitch]

I got the same message the other day. It flashed quickly on the dash and went away. Hasn't come back. I'm now way out of warranty so.... I'm just going to drive it and see what happens. Last time I pulled codes I came up with: P1475, P1193, P228, B16B7. Granted I had just removed the air filter box to replace a defective shock and the CEL lamp came on after I re installed everything, No I didn't disconnect the batt when I was replacing the shock. Probably was a bad Idea... Cleared the codes and all has been good.....

 

[TCDiesel]

LOL. LETS SEE, I've been running Deionized water during summer months for 12 Years in the fleet of trucks My businesses own, We keep the DEF tanks Full when convenient, We make our own DEF and I NEVER had a Message for any DEF reasons, Never had any DEF system Fail.

I keep reading DEF comments all over the WEB/Forums Etc, and I See WHY owners have problems with DEF. If you apply/practice DEF info you read about Your DEF problem will Never END.

Keep your DEF tank FULL when convenient, and try not to let it drop below 1/2, at just below 2/3 it will take 2.5 Gallons to fill on CC/LB

 

[kthaxton]

I have had no problems with DEF, I usually only fill it half full unless I am going to be towing...no problems. I also have the warm fuzzy that I am doing my part to help humanity by not releasing NOX that I need not release.

When should I expect to see all of these problems you speak of?

 

[TCDiesel]

Well that warm emotional fuzziness your get'in has no effect on Humanity. You would have to drive 300,000 miles to equal the effects of 1 lighting strike has in production of NOx, and more than 1.5 Billion lighting strikes happen yearly.

So the entire DEF system has little to No effect on NOx production levels , (ERG does the most of the lowering of NOx) Its Good to Know Kthaxton get'in some effect from it.

 

[kthaxton]

So, the automakers and the EPA, got it wrong, and TCDiesel is the one with the correct information? Of course. You should let Cummins know about your findings.

But then there's this:
"Fossil fuel combustion, microbes in the soil, lightning, and forest fires all produce NOx. Scientists think lightning's contribution to Earth's NOx budget -- probably about 10 percent -- is relatively small compared to fossil fuel emissions. Yet they haven't been sure whether global estimates of NOx produced by lightning are accurate."

If you have better information than NASA, they'd love to hear from you.

Oh, and, this too.
"Q. What are the advantages for the fleet in using SCR technology?
A. Cummins 2010 engines will deliver what customers need in these challenging economic times. Cummins 2010 heavy duty engines utilizing SCR will provide substantial fuel economy improvement, up to 5%. SCR catalyst technology allows much greater NOx conversion efficiency, thereby allowing the engine to be fully optimized, which contributes to this fuel economy improvement. Another benefit to the improved fuel consumption is less frequent Diesel Particulate Filter (DPF) cleanout, thereby further reducing costs."

[TCDiesel]

Kthaxton like usual, Were did I say anything about fossil fuel combustion, the DEF is not the NOx knock out it only get the levels to meet the EPA requirement of near 0 PPG.

Just another irrelevant comment that diverts the subject of DEF Use, Kthaxton your comments are hypocritical, if you that concerned about NOx and other Unknown's start walking your NOx and other possible contaminates will be 0 levels with no ICE ( Internal combustion Engine) use.

 

[kthaxton]

Kthaxton like usual, Were did I say anything about fossil fuel combustion, the DEF is not the NOx knock out it only get the levels to meet the EPA requirement of near 0 PPG.

I'll dumb it down (Like usual),

You compared lightening strike NOX emissions to automotive emissions, I was pointing out that lightening contributes little compared to the burning of fossil fuels. If everyone did what you do, we'd be worse off.

Just another irrelevant comment that diverts the subject of DEF Use, Kthaxton your comments are hypocritical, if you that concerned about NOx and other Unknown's start walking your NOx and other possible contaminates will be 0 levels with no ICE ( Internal combustion Engine) use.

"Like usual", you make little sense, and I diverted nothing, you made some incorrect statements, and I pointed them out. And, by using DEF, my NOX levels are very close to, if not, 0. Explain to me how that is hypocritical?

While I am not certain why or how your fleet is able to run DI water without issue, I'm sure it is illegal. For the vast majority of us, DEF causes us no issues, so why not stay legal and emit less harmful pollutants?

 

[TCDiesel]

Khaxton, I don't run Illegal, I retained the correct Fuel analyzer from the MPCA and I tested many different Urea saturation % VS the 32%. You can dropped to level of 10% and still hit the CAA Near 0 PPG, Not always if I was to % of 10% Urea it drop NOx to near 0 80% of the time. the rest of the time is single digit PPG.... Heck I would have to drive 2+ million miles just to Make 7LBS of NOx by volume, at 10% concentrate.

You can also due a Search back to 2015 I tested My Eco and found that it was conditional, all 2 years before the EPA agreed with Me....

Khaxton the DEF just does clean up, the EGR weather in Head or external takes care of 50-70% the catalyst does 10-20% NOx. IMO
