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 of Diagnostic Trouble Code P2454 Category Powertrain
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.
