There are two electronic sensors, one on either side of the DPF and two steel tubes, again one on either side of the DPF. Does anyone know what the sensors measure? Are they O2 or pressure? What should the resistance across them be when DPF is clear? Are the tubes pressure sensors and what is the differential they should see?
there r two O2s, three temp, and two presure sensers... the pressure lines see more psi on the inlet side of the DPF to determin when a regen cycle should occur... "getting plugd".. temps moniter so the DPF dont have a melt down and the o2s do the same thing as usual... read the amount of o2.. sounds good but mine didnt work so well.
That's kinda where I'm headed. I'd like to put twin stacks on. The flange that the dpf bolts to the cat through seems a good spot to adapt the stack pipe to. An elbow to turn up through the box, a Y pipe and two more elbows then the stacks. I'm thinking that one pressure sensor just after the cat and another at the bottom of one stack and the ecm should see a pressure differential but never enough to trigger a DPF regen. The temp sensor position wouldn't be too critical and neither would the O2 sensors. I'd like to see the output of all these sensors from a data logger when the dpf is installed and working correctly to know if its as simple as that or if there's sensitivity to what the pressure reading actually is.
When that DPF gets clogged... Come see us! Eventually that DPF will clog and to keep you running legal you will have to replace that dpf. We have solved the problem by building a kit for that specific type of truck. Give us a jingle if you have any questions... Jim Sutherland www.cleandieselspecialistsinc.com
Lol I think most are!!! They make good homes for little bugs. But most businesses and people who want to keep their systems legal this is a good option for sure. Way Cheaper and you can service it for life without having to buy a $2500 filter again. Crazy OE mfgrs. burnout
