2002 4x4 with 176k

the dtc just popped up. i know it is in the egr circuit somewhere. i recently replaced the dpfe sensor, about 15k miles ago. any suggestions on where to start looking?

cleared the code and it was reset after 3 drive cycles.

i've popped the dpfe sensor and there was a little water in it. i will let it dry out and see what happens.

i checked the solenoid and it functions, in turn, the egr valve function properly. i will replace the dpfe sensor and see what happens.
