P141f is the code i keep getting since i started working on the hino 2012 truck..i changed the dpf filter after i saw lot of dark and sometimes white smoke coming out of it.,the igniters are new and so is the nozzle and flame sensor..it worked fine when i changed the dpf but now it's back with failed regen and the code stated above plus another code p2030 under BCU..today i even changed thermo sensor and gas sensor and temp sensor to no avail..i tried the regen and stayed the wole time like that unfinished..i also could erase the codes but 141f is back.
Upon forced regen using the dx2 i noticed dpr exhaust gas temp [in] was stuck at 32f when i changed the sensors today and attempted regen it was stuck at 152f ..i know something is wrong when i amell some fuel burning time to time ..
I really hope you guys gonna help me figure this out..
Thank you very much..
