Hi all, newbie here, greetings from Canada
I normally find what I'm looking for without posting, but this one's got me stumped.
Background:
Machine is a 2014 T750 with a Tier 4 interim V3800 from Kubota. I bought the machine with 4800 hours on it from a Ritchie Bros. When the machine arrived it had a pretty good rod knock, so we tore the engine down and rebuilt completely. Cylinders were bored .020 over and all OE Kubota parts used.
With the engine reinstalled I'm getting issues with DPF. Initially it was throwing an E523601-00 (Exhaust Gas Temperature Sensor Fault. At the same time as throwing this code it would shut down, and inhibit starting till either I unplugged the 3 EGT sensors on the DPF or let the machine cool for 30-45 min. I resistance checked the sensors and found one of them to be reading erraticly, so it was replaced. Issue still persists, and the machine goes into regen (stage 1) much more than I think it should.
The only thing I hadn't gone through was the DPF. So as per the dealer's suggestion I removed the DPF and had it cleaned. I just got it back in the machine today, and ran it for a good 45 min or so. It didn't shut down, but the machine still attempts to regen much more than it should be, to the point where I hit the manual override to keep it from going into that mode. As of now it's throwing two codes. E523602-00 (DPF Fault) and M5902 (DPF inhibit regeneration switch error ON). The first code didn't show up until about 2 minutes before I shut the machine down.
I'll be having the dealer coming out Monday to plug in and reset the soot level via Diagmaster, as well as do a supply pump calibration and see if we can't figure out why it keeps throwing codes.
Any input anyone would be able to offer would be greatly appreciated!! I've already gone through and done the voltage checks found in the manual for the EGT sensors, they check out fine.
Thanks in advance!
