Cummins ISX CM871 Technical discussion

Geez, that seems like a bunch unless the truck in only running 300 miles a day.

Unless it's really hot or cold, the APU doesn't need to run constantly.

Lets not turn this into a APU thread

 

hello I have a cummins isx 2009 model engine serial number79287765, ok ive cleaned the dpf the pulled it all a part had the catalyst and filter cleaned again replaced map sensor cleaned egr dif press sensor replaced dpf press sensor replaced dpf egt sensors truck uses no oil no coolant but I still keep getting the 5018 with 11 fault codes and the truck derates o yea also cleaned the 7th injector anybody have any ideas thanks pj

 

from the top I pulled the dpf cause I was getting a fault 5298,had it cleaned put it back together. then started getting the 5018 fault code fmi 11 root cause unknown so I pulled it all a part again had the catalyst cleaned and the dpf had a forced regen ran after each pull.fault code went away for a while the I got a doser fault code cleaned the injector had a forced regen dune again. couple months go by started getting fault code 5018 witch is not doing a complete burn do to uneven heat across the dpf so I took it to a shop had them do a forced regen and watched temp sensors face 575 middle 1040 tail 1000 roud about temps during all this ive been replaceing sensors due to haven 622000 miles on truck figured its time to replace egr press sensor and dpf press sensor at same time I have also replaced my map sensor sorry about the horriable typing and spelling im more hands on
