Mitsubishi powered. I got these faults. 3348720 DPF temperature too high. 3354864 DOC cleaning state. Machine not in derate, and we're gone when I arrived. Codes didn't clear when requested. Data pic is engine off. When started, all temp values go up together, with 5%.
Had the exact same codes on a sk140 with a Mitsubishi D04EG. Mine did not have an after treatment fuel injector. I pulled all the fuel injectors and sent them out for testing. All four failed. Installed 4 new injectors and haven't had any issues yet. I also sent the dpf/doc out for cleaning.
If you ever need injectors, feel free to contact KRIG Pyskowice. I think they’ll sort it out for you
