I have a p0401: low egr flow code. The passages were gunked up cleaned them with no change. the egr solenoid was faulty so I replaced it. The egr valve functions as it should suck on the nipple car sputters and feels like its gonna stall. The only thing i can think of is the dpfe sensor. Is p0401 the code you get from a failing dpfe that the computer still thinks is good?
