A quote from the dealer:
Per our conversation yesterday, we found the DPR system has failed. We also found 3 of the 6 injectors overfueling. We are recommending to replace all 6 due to the fact that if we don’t replace all six it can cause damage to the new DPR.
It has no power and pops thru intake, bucks and surges under acceleration. Any ideas? Passes all of the dx tests in hino explorer. The only spec out of range I have found so far is turbo boost is around 10 psi, 15 psi is spec if I recall. Again any Idea? I rarely work this product line.
I'm just about to buy a Penske 2009 Hino 268 with 170,000 miles, but having come across this terrific thread of yours I'm nervous about how much bother Hino trucks might be. Are Internationals with the DT466 or Freightliners with a Cat or Merc likely to be less trouble? Thanks.
These techs just suggest more tests which just costs more money. We deliver laundry to our hotels in the Rocky Mountains so not a heavy load. Could this be an altitude issue? It always seems to happen around Lake Louise Alberta. I also have a 2009 185 which had the same issues but since the recalls have been done it is fine but too small to handle our summer business. Any suggestions?
Hi, I have a 2008 Hino 268 with 300,000 miles on it and am having constant issues with the DPR. It frequently asks for a manual burn instead of doing it automatically. Eventually it goes into limp mode and we have to take it into the Hino dealership to have it reset. This has happened at least 15 times in the past 3 years. They say that all the recalls have been done and they have brought in techs from Hino Canada.
I have to make 2 posts as I was too long. I had a mechanic look at it and I told him about the 3 holes in throttle and he said he never heard of it, telling me I need throttle body and egr valve. Like to what you think.
