    2019 Hino 338 p0005 +p0007 codes

    Sent it to the dealer and it was in fact a fuel cut valve. Part was covered under warranty but still had to pay for the labor unfortunately. Thank you for the response and the attached service bulletin.

    2017 Hino 338 - Truck shakes at 1000 RPMS

    It doesn't happen in 1st gear revving up to 1000 rpm but it is very noticeable going up to 50-60 mph and letting off the throttle and as it comes back to 45-50 mph the truck will shake.

    2010 Hino 338 Wire/Relay issue

    The high idle ended up being a wire that runs over the top of the dump body that was corroded. That is why sometimes it would work and other times it wouldn't. Thank you again for all your help, this forum has been a lifesaver for my company.

    2010 Hino 338 Wire/Relay issue

    The truck was having an issue engaging the High Idle. After checking relays and fuses the truck will not start and when I put the key in the ignition the shifter lights won't say what gear the truck is in so I think they might be related. I can force start the truck from underneath just not with...

    Hino 338 Engine Break Usage

    A new injector was installed just this past week and the NOx injector was replaced just about one year ago plus the truck should have received any software updates last week. I will monitor the situation and let you know if the malfunction comes back up. Thank you for the response.

    Hino 338 Engine Break Usage

    I have a 2011 Hino 338 that I use for trash removal services and the truck experiences a lot of stop and go usage and little to no highway miles. Recently I have been getting a SCR malfunction and a P204F, P0410, and P0410 codes come up and the truck will run sluggish. The code can be...

    DEF Parts Diagram

    Hi, my mechanic is an older diesel engine mechanic and isn't too familiar with the newer Hino trucks and I currently have a 2008, 2011, and 2016 Hino 338. I currently just had a few codes(P204F and P20E8) that came up and after reading through some of the forums I found the answers I needed my...

    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    I am having an issue with the check engine light coming on still and my mechanic thinks there is a butterfly valve that isnt opening to allow the correct air flow. The picture was taken from the front of the truck looking towards the back and I am on the drivers side of the engine compartment...

    Swapped out the fuel pump and we are getting fuel to the engine so it appears that was the issue. The driver took the truck out and after 5 minutes of driving it started acting up again. He could go about 5mph up hill and rolling down hills no more than 20mph. The truck feels a bit sluggish now...

    We tried that and the fuel isn't getting to the injectors. We removed the return line on the tank and there was little fuel coming out while we were turning the truck over. Bench tested old SCV and it was working and so is new valve. At this point I think it may be the fuel pump itself.

    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    When the SCV is removed we can get fuel to come up to that point. once we plug it in we turn it over for 30 sec or so and still wont fire up so it seems as though the valve isnt opening because fuel is getting to valve without it. We tested the SCV and the fuel just isn't making it to the...

    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    checked and cleaned the banjo bolt and the valve but our fuel filter doesn't have a primer pump. It is a fuel separator/fuel filter combo. We did replace the scv and checked that fuel was getting to that point but when new scv was installed the engine fired up but wouldn't continue to run (after...

    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    We had spoken earlier about one of my trucks having a fuel restriction problem whether it was the scv or some type of blockage in the line. We attempted to swap out the scv for a new one but the dealer sent us one that does not match the one we have. So until we get the part we re-installed the...

    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    The tank is new we replaced it about 6 months to a year ago because the old steel tank rotted out. Replacing the fuel filter and cleaning out the fuel/water separator has fixed some issues. The check engine light doesn't turn on unless the truck is making an extended climb up a hill with a...
