Anyone get a P047E or D code

[RhinoJT]

Got a P047E and D, exhaust pressure sensor circuit B intermittent. I got back from a 2 week work trip and the Jeep sat, have t had this issue untill now. Only thing I can think is the soot level is at 70 percent and maybe something is getting clogged or gummed up from it sitting. Would running a manual then help. I haven not been able to find much on these codes online or the forums.

I would clear the code and see if it comes back. If it does. I would next check the wiring at the senor to see if a critter chewed on it since it sat for 2 weeks without running.

Check out the link I posted.

This is the second time the code has come back. Looks like there is a pre and post DPF sensor, I checked all and nothing looks broken, all seated and no broken/chewed wires from what I can see. I have only driven the jeep for a few short cycles since I got back, so I just got done taking it out for 45 minutes on the highway and around town. I have the Idash and the soot level was at 70%. I kept the rpm’s above 2k and about 15 minutes in I saw the soot level jump around, went down to 68 then jumped up to 80 then 81. The jeep started a regen pretty much right after that and dropped down to the base level at 8%. No CEL for that entire drive cycle. Wonder if one of the pre or post sensors got gummed up. Guess we will see.

I have the iDash too. When my SL% gets to 80. It regens. So what you seen is about right. It takes about 12 minutes and about 12 miles for the regen to complete it's self.
