... never gets a chance to do a regeneration burn and eventually the DPF blocks up. The whole reason the Diesel Particulate Filter came along was to clean up the diesel car image (Euro 5 Emissions, 2009). Is the AdBlue causing issues? But, it’s not all smooth sailing, here are some of the problems and solutions we’ve heard about. I … Need help figuring it out. The DPF is an emission filter that reburns Particulate Matter (PM) much like a Catalytic Converter (CC) does. Known faults with the D-max. “You’ll notice a reduction in power during a regen,” notes Nace. *The Stop Engine Light is on because I'm betting that a sensor on the exhaust side is not allowing the temp to go above the required level to activate the manual regen. Is the Isuzu D-max a god ute? All of these troubles can be an issue for your work truck Read More "WE CRACKED DPF DPD OFF ON ISUZU GX, FXM, FXY, GIGA, N AND F SERIES" Are you experiencing problems with your Isuzu Truck with DPF doing DPF Re-generations more frequently ? This is not a unique problem to the D-max it plagues all diesel engines living in the city. This code tells us that the exhaust temperature coming out of the turbo charger is not high enough to support the burning off of the soot in the DPF. 2011 Isuzu NPR red exhaust light light, amber regen light blinking, engine derate light on, no codes, exhaust differential is at 0.02 psi. Or is the DPF light now flashing but the truck won’t do a Regeneration? The DPF was manually cleaned. Regeneration takes anywhere from 5 to 25 minutes, depending on lots of different factors such as the amount of soot built up, type of engine and vehicle operating conditions. A computer sensor monitors the DPF and a dashboard indicator light notifies the driver that the regen is taking place, or the DPF is now cleaning. Optimize your Isuzu diesel engine with our DPF delete service and enjoy the rewards of improved fuel economy, engine performance, and reduced maintenance. Truck Agriculture. - It doesn't sound like a DPF problem necessarily, but more of a sensor issue. The Isuzu D-Max and MU-X twins are popular amongst the 4X4 fraternity because of the simple, hard-working engine and reliable mechanicals. Toll-Free: 1-855-932-0060. Skip to content (02) 99795933. Isuzu D-max common problems. Toll-Free: 1-855-932-0060. The Isuzu Rodeo's fuel pump system is known to develop small holes and leaks, which causes the vehicle to lose power on acceleration, show inconsistent fuel gauge readings, and issue smoke from the exhaust system. The Diesel Particulate Filter, commonly referred to as the DPF, can turn into one of the most frustrating parts of maintaining your '08-'10 Isuzu NPR medium-duty truck if it isn't properly taken care of.. DPF Regeneration Cycles: An active regen cycle is a normal process that takes place as the truck is going down the road. This burn off process is also known as regeneration. The Diesel Particulate Filter (DPF) is best described as the “ticking time bomb” in most modern diesels.Similar to EGR problems, the DPF can become clogged up from city driving where the car does not get up to temperature.. If you can't get the exhaust temps hot enough, the truck will not regen under any circumstances. (Even our work Hilux had a DPF problem at 40,000Kms) Diesel particulate Filter Problems … DPFs particularly cause issues for non-highway type applications, and the following series of problems can progressively develop… The number of “forced regenerations” increase, necessitating the truck to be parked up for 20 minutes at a time, to burn off the soot under higher fuel usage conditions. That was the reason Isuzu changed the dipsticks, not because of regeneration issues. Code P242F will set when the soot / ash levels in the aftertreatment diesel particulate filter system have went beyond the most severe possible. Isuzu learned that in those situations, if the amount of oil in the crankcase was reduced by 2.5 quarts it would limit the amount of oil that would end up in the intake system. The differential on the Isuzu Rodeo tends to run hot, which causes the differential fluid to break down.
