Fault codes, are they serious

[JReichenbach]

Hi, I'm looking at a 2013 2500 with 120,000 miles on it. It has a P0420, P20EE, P026B, and P249E codes showing, MIL light was on, erased codes and they didn't come back after a short drive, anything to be concerned about? My 2005 is a lot less complicated than this one looks to be, any insight on these codes would be helpful. Thank You.

Mine gets P20EE when it needs more def. And (I think) sometimes when it needs a regen. I just add DEF and give it a hwy drive.
My def gauge is not accurate so, even if the gauge says full, I can (often) still put in 2.5 gallons.

At 120,000, though it might need the NOx sensor replaced ??????

That's the only code I'm familiar with.

The repair bill could easily run into the many thousands once you make the deal and are on the hook . Some codes are just nuicance codes, some will start the "countdown to death" as I call it, where a mileage timer begins ticking the miles off until 5mph derate.

If you live in an area that requires emissions testing I would absolutely make the owner "pay up" and figure this one out before making a purchase.

My DEF gage sits at full for a long time before it budges. Then it steadily creeps down. I plan to top it off at half. The diesel stop nearby at the Cat Scales has a Def pump.

comrade - i did a quick google search on some of those codes. most seem emission related. i would be careful if i were you. cheers!

Get it taken care of.

Since no one else felt like providing the actual code definitions:

P249E - Closed Loop SCR Reductant Injection Control at Limit - Flow Too High

P0420 - Catalyst Efficiency Below Threshold

P026B - Injection Timing Performance

P20EE - SCR NOx Catalyst Efficiency Below Threshold

I would insist on having the truck taken to a local dealer to have all of those fault codes addressed. Some may just be simple faults that can be erased; others may be indicative of hard failures that need to be fixed. Either way, let the owner and the dealer sort that stuff out before you buy.

That DEF gauge behavior is very typical of the 13+ RAMS. Also, the ability to add ~2 gals beyond the full gauge indication.

As noted above it could be simple, or very expensive. As long as you factor in the expensive part and the truck is priced accordingly you should be fine. It would be my preference that the truck be fixed before purchase, but then the sales price will most likely reflect that. I guess it comes down to are you feeling lucky today?
