Been having the “bucking and surging “ symptoms last month or so, same as a few years ago.

I figured it was the DPFE part that needs to be replaced (again). This time it threw a CEL on me.

I ran a scan and this is what it showed. Truck runs fine at highway speeds, no power lose. All the same symptoms and complaints we’ve all had related to this part.

Just want to confirm these codes are related to DPFE part.

Yes, P139C is related to the EGR DPFE sensor. It states that a hose is off or plugged to the sensor. Have you checked for that?

I have the whole replacement unit.
Just wanted to make sure it’s that damned part!

Have you checked for hose blockage or a disconnected hose to the EGR DPFE sensor?
