Code P2454 help

Hello all, for the past week or so, I have been searching this site over trying to figure out the answer to my problem, but to no avail, everything I have found on the topic had to due with people who have already put aftermarket exhaust on. My truck is off the showroom floor stock, and after pulling a 36ft cargo trailer a couple weeks ago, it kicked the P2454 code, then had trouble pulling the trailer. It didn't miss, spudder or anything like that, just a loss in power.

I have talked to a few people on the matter, but I would like some more opinions to better figure out how I need to attack this problem. Talked to the head service tech at the local Dodge house, he thought it is a fuel problem and told me to start with the filter, so i started with that, changed the filter to which I found out it was in dire need of replacement(I have just recently bought the truck and seems like the previous owner never changed it.) and it seemed to pick up some spunk. Then more driving without the trailer, it would still kick the code on and off. So he thinks that I might need to have a new lift pump and that I need to check the fuel pressure.

I have also talked to a general mechanic who is a friend of mine, but he seems to think that it has something to do with the particulate filter or that valve(can't remember the name of it) that has the two hoses on it that go to both sides of the filter.

Does anyone have any input that would help me have a confident way to attack this problem? Thanks in advance.

I am no expert on these matters and I'm sure some others will offer up much better help than i can. First off you would think the head service tech would know what the P2454 code is.

Definition Diesel Particulate Filter Pressure Sensor "A" Circuit Low


The emissions systems on these truck cause 90% of the problems. If you are still under a warranty, take it to your dealer and make them fix it. If not.....one option is to delete all the emissions crap and let your truck breath and run better than ever.

I'm sure more knowledgeable folks will be along shortly to give better options.

Not under warranty, and believe me, as soon as I can justify the money, I will be removing all the emissions crap on it. I just need to find out what is causing the problem, so I can spend my lack of money wisely.
