Don't have the receipt in front of me, but it was low flow EGR, I think P0401

That's not a dirty EGR valve. That's either a bad DPFE or a plugged EGR passage through the intake.

Thanks. So I could clean it out and/or replace the DPFE? How to clean it? I think I know where the EGR is located - driver's side back of engine, right on top like a mushroom. Not sure where the DPFE is.

Differential Pressure Feedback EGR sensor also called a pressure transducer. They fail by the hundreds.

Well, if you don't want to get it diagnosed properly, I'd try a new DPFE

What about the cleaning? I've seen responses suggesting wire insertions and chemical breakdowns (B-12). I'd like to do this myself because it seems so simple, as is buying a new DPFE. I think I should do both, no?

BTW, I've gotten the same response before - replace the DPFE. This just doesn't seem to fix the problem. If there's carbon buildup, then I think it should be cleaned out. How to do this is the question. With a clothes hanger or with B-12 or something like it. Hey, I don't know what I'm doing, and that's why I'm here. There's mention of gasket replacements, throttle body cleanouts, hose replacements, etc. I'd just like a straight answer.
