Where can I get information for the DD15 Motor and emissions sensors and replaceable parts. For example what I'm looking for, similar to the Cummins website for the N14 I could search all the parts. Then lookup availability of those parts. Does Detroit have something like this? I like to change parts before they break on the road. This last trip I had the yellow emission warning light come on. It was the outlet NOX sensor. I couldn't find the part number without calling a dealer. Since I got home I called Dealer for all the sensor information. They only gave me numbers for the One box. I want to change the parts in the EGR system and the DEF. Thanks
