Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer. What are the other codes that you now have?
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!
Ok, give me a few minutes to get that. Be right back.
Ok, the case number ***** P2281 is S1518000016
And this one was for P0420. S1508000202
