Customer Question

I have a 2015 ram 6.7 daily driver towing 26k.
Had a cell at 7k mi. And local dealer found code p2459. Did the re flash, fuel filters and air filter service. Test drove and light is still on but dealer said I could drive it. So I'm at 16k now and truck goes into limp mode towing at full power in 4th at 2500 rpm 60 mph. Also have 5or6 codes now on the computer all emissions related as far as I know.

Ok, thanks. Let me research this a bit and get back to you. Should be within 20 minutes or less.

Ok, after looking at bulletins and other similar cases, you may have an issue with the air intake system. Any leak or restrictions between the air cleaner and the intake plenum can cause the P2281 and in turn cause too much soot to build up and cause the truck to go into a regen strategy too frequently. That will cause the P2459 to set and then reduce power. There are a couple of Star cases that discuss this. Your dealer should know about this and I recommend you ask them to pull up those Star cases. If you want, I can send you the case number(s). Once the intake system is good, then a forced rgen can be performed and clear out the DPF. After that you should be good to go. One other thing is make sure you are using ultra low sulphur fuel and oil.

I hope this helps!
