2011 Prostar Plus, Epic Fail

There's almost nothing you can do in the field as a driver to deal with those lights. A trip to the dealer is about all you can do. Probably Monday? What was the problem last time it was in the shop for a week and a half?

Happy thanksgiving , hope your luck changes for the better!

 

Stop and check engine lights usually mean the engine is seeing the DPF loading at level 4, which is game over for you. Level 4 requires a laptop to run the regen. Driver controls will not work.

 

all trucks break down is part of the job i know it sucks sooo bad i been there just stay warm n take this as a test u will be stronger once u come out of this, i spent 3 days stuck in denver thru a snowstorm in new year in 2010 just be thankful for what u have in your life today by the way im working today wont be home till tomorrow its just part of the job, stay up driver.

 

DPF Lights on? Oil Pressure?

 

Had a similar problem on my Volvo with an ISX Cummins. Kept saying regent required, check engine light would come on, finally it derated. Turned out the DPF was toast, it kept trying to regent but couldn't. The only clue was when the techs at the Buffalo Truck Center in Buffalo, NY took it apart to clean it and the DPF came out in pieces.

The pressure differential sensors were also bad. After everything down there has been replaced, I've had no problems, knock on wood, lol.

 

Yes, like PackRat said, sometimes the regen is doing nothing because the DPF is already plugged to capacty or damaged internally. There could sensor problems and it is reading the differential pressure wrong.

 

Also the AFI (Aftertreatment Fuel Injector) could just simply be clogged and not letting enough fuel out to get the Temps. up. What kind of work did you just have done? EGR Cooler?
