I went and ran the machine with the DPF disconnected and it operated for about 10 min without throwing the code. Im going to clean the dpf tomorrow and see if i can get it back to work.
bummerNo you can't,
id like to start with simple first. do you know how much the kvgt shloud move? i get zero with machine shut doewn and .156 to .220 working it.Ive diagnosed a few of these,
No I didn't probably should've but it has less than 100 hours on all new filters and fluids. The charge pump feeding the egr was putting out 210psi no fluctuations coming out of the egr valveDid you change the oil and filter when you serviced the screens?
Egr screens were removed and cleaned. Booster pressure was good and getting 4.97 volts to the kvgt sensor plugFirst, did you remove, clean and inspect the screen at the EGR valve and did you verify good booster pump pressure? Did you start the machine and observe KVGT position while operating with and without load? Are you producing boost. The KVGT is hydraulically controlled. The computer has to see values within spec before the code can go inactive.
