What is the Regen frequency for Isuzu NPR?
But I am stumped, my local Isuzu “lead tech” is stumped. This truck came in with a p244b – dpf high differential pressure, p2463 – dpf high soot accumulation, p2459 – dpf regen frequency. I perform a forced selective regen. System goes 200 – regen start. Sits there awhile. then 220 – temp rise.
What’s the history of the Isuzu NPR network?
History, in the last year, its gotten NOx1 and 2, DPF, Last time it was here for a EGT temp sensor code, where the egr temp sensor broken off in the exhaust manifold. So it got a sensor and manifold. this last go around I did a DOC, EGT1/2, aftertreatment injector, so except for the SCR, the aftertreatment is all new.
How does Isuzu make fire in Regen active?
It does make fire now, but it doesn’t always go into the regen. As I said above, it will sit at “200-regen start” forever, then sometime it will start the regen (370-regen active) then a couple times WHILE IN REGEN ACTIVE, will kick out into regen start. I see nothing changing when it…
Is the EGT temp sensor broken off in Isuzu?
I subbed for 3 days on Isuzu site and its the same info as on my scan tool, so that was a waste. History, in the last year, its gotten NOx1 and 2, DPF, Last time it was here for a EGT temp sensor code, where the egr temp sensor broken off in the exhaust manifold.
Are there any issues with my 2012 Isuzu NPR-HD?
I have a 2012 Isuzu NPR-HD with approx 90k miles and am having issues with DPF regen and Catalytic Converter. First off when driving highways speeds, it does a regen about every 125-150 miles. If there is no traffic and moving ok, there is no issues.
How does the Regen button work on an Isuzu DPF?
When a manual regeneration process is started, the driver pushes the regen button, the light flashes and then the green light comes on. Untrained operators may think “Oh, now it’s okay to continue driving or otherwise operating the vehicle and the regeneration will continue behind the scenes.”
Why does my Isuzu NPR diesel engine not start?
If it starts with one of the fuel lines to the injector capped, you know that that injector is allowing fuel to pass and not allowing enough fuel pressure to build in the common rail to start the engine. My test showed that the injector on cylinder #4 was allowing the fuel to pass and not allow the pressure to build high enough to start it.
How does the Isuzu NPR diagnostic network work?
Nothing happens. I take it out and beat it to get the exhaust hot, return and retry, it goes 200 – regen start, 220 – temp rise, then 370-regen active. EGT gets to about 800*, it goes BACK to 200-regen start and sits there half an hour, then kicks out and sets a P244C – too long in regen.
What kind of differential pressure does an Isuzu have?
I have this 2012 NPR, Im calling out more professionals for assistance, seeing as many of my die hards have left the mothership and came here. But I am stumped, my local Isuzu “lead tech” is stumped. This truck came in with a p244b – dpf high differential pressure, p2463 – dpf high soot accumulation, p2459 – dpf regen frequency.
What kind of diagnostic network does Isuzu have?
So it got a sensor and manifold. this last go around I did a DOC, EGT1/2, aftertreatment injector, so except for the SCR, the aftertreatment is all new. I did have a p0172 code set twice, which I cant prove out. data lists o2 content at 15% and 16% idling, I haven’t watched it driving.
What causes an Isuzu car engine to not start?
Dead or weak battery. Bad starter motor. Oil viscosity too heavy. You’re out of gas. Your engine stopper is bad. Restricted air filter or air inlet tube. Restricted fuel injectors or fuel lines. Blown engine stop fuse. Low or no voltage to glow plugs. No cylinder compression – stuck valves or broken pistons.
Do you leave the Isuzu box truck during regeneration?
During this mode it is important to remember: Don’t leave the Isuzu box truck during regeneration. Make sure that there are no flammables near the muffler, DPF, or exhaust pipe which may result in a fire. Remember that the temperature of the exhaust gases are high enough to burn you.
How often should DPF regenerations take place in diesel engines?
There is only one answer to excessive DPF Regeneration: Eliminate or dramatically reduce diesel particulate matter (soot). If you can achieve near perfect combustion efficiency, exhaust soot drops to the point where DPF regenerations or “regens” would be extremely rare.
What is the priority service program for ISUZU trucks?
Our Priority Service Maintenance Program (PSMP) is a service program that is specifically designed for your Isuzu truck whether it has a gas or diesel engine.
How many seats does a Isuzu N series gas truck have?
