P0148 - P0193 Help Please
I re-installed my quad xzt box two days ago. Yesterday I thought I noticed a little more injector rattle. This morning when I left for work my truck started bucking and farting and burping black smoke under acceleration around 2k rpm. I stopped on the side of the road and pulled the box off and used the by - pass plug it came with, so I could leave the harness there. I called the delaer while I was driving and asked them to ready the diesel tech who recently replaced my #6 injector. They informed me he was no longer there[:@], and it would be the end of next week before they could look at it because the only diesel tech there was booked through then [:@][:@]. So I continued on with my day and it smoothed out after a while. On the last leg of my trip today I stopped and had my bed rail protectors replaced. When I left there to come home it started acting up again and threw a CEL. I got home and did the key trick and the codes I got were P0148 (HPCR Checksum) and P0193 ( Fuel pressure sensor voltage too high). Now the quad harness plugs into the rail pressure sensor, so I took the harness off. Then I drained my fuel bowl just to make sure I didn't get some watery fuel, it was pristine.I just returned from a test drive and it seems ok now. Should I jsut go to an auto parts store and have them clear the codes? Will the dealer be able to tell I have done this? Should I just go to another dealer and let them check it out?
