Toyota Hiace, KDH201, 2kd, Diesel, DPF soot Accumulation – level all the way up on the cluster.
had the pleasure of working on this guys with a DPF issue showing on the instrument cluster with a bars to high could this game still on there now funkos so up the car DPF light flashing a look at the temperature probes don’t find anything wrong has to go have a look to see how we can couple DPF out nothing we work so then we have to do is we had to put a 200 resistor on the exhaust temperature bank 1 sensor 3 press the DPF button and wait for it too just happen
the particulate matter accumulation radio ratio and all the way down to 14% and still watching the catalyst differential pressure is almost .02 kPa difference the particulate filter differential pressure 1.3 kPa and has not changed it looks like the trick with a temperature probe shorted with 200 ohm resisters really works
I’m waiting waiting by dick out matter accumulation ratio down to 4% and waiting for it to hit 0 and I’m hoping that the lot now down to 2% to 0% and I want the system to then self shutdown what I ended up having to do was stabbed my foot on the accelerator the minute I did that and the DPF mode came out the check engine light and DPF light stop flashing when out and the RPM can back to normal RPM speed therefore this thing is now solved
I then switched off ignition so the vehicle then stop stop the engine and then turn the ignition back on and I watched the exhaust temperature bank 1 sensor to drop from 700 all the way down to 81.2 that temperature is the same as the exhaust temperature bank 1 sensor 1 the exhaust temperature bank 1 sensor 3 is still at 742.5 degrees with ignition on as it has a 200 ohm resistor what im going to do is run the vehicle and see what happens because it looks like the whole lot is done by a mathematical equation and not differential pressure sensor being the only thing making the system be more blocked so to speak but then proceeded to River up the vehicle to 2000rpm watch the temperature exhaust sensor bank 1 sensor to go from 81.2 degrees all the way up to 450 and then I slowly let the RPM off and it’s slowly decreased all the way back down to 81.2 the particulate matter accumulation ratio is still at 0% so it looks like this is actually going to work leaving it in there I really like to see what happens with the vehicle in a couple of weeks time
