EGR DPFE Sensor Assembly Replacement Write-Up (LB5Z-9J433-B)

[got3fords]

What was the code you had?
and
What was the DPFE sensor reading (Live Data)?

or was this a blindly changed shot gunned part?

Generally, the associated codes for the DPFE - P139A - P139B - P139C and P0401 - P0402 will clear on their own after 3 drive cycles with EGR events - (light will go out) and 40 warm up cycles to fully clear from history.

I am about 90% complete on my EGR System operation guide - so posting soon.

Since you didn't quote, not sure who your question is addressed to.

Is there @ny sort of code reset or is it pretty much just plug and play reset?

I don't think he had any codes, he was just inquiring further into the DPFE thing in general after I brought up.

Shout out to Trash Panda. Great write up. I have a 2019 that has been running like crap for months. I ran across this thread and ordered the replacement sensor from Amazon. The ad did not show a brand but when received, it was Branded FOMOCO, Malaysia just like the original. I shredded my arms trying to get the lower lines off but nothing a few band-aids and time won't fix. Anyway, The result is fantastic. This simple fix made an unbelievable difference in the way my truck drives now.
Big thanks to everyone who has added to this thread. I was able to glean A LOT of very useful info from this thread alone.

I had about 75k miles on mine when I replaced my DPFE sensor. I had no real reason to replace it, except for a couple weird shifts here and there. After I replaced it, I have noticed no noticeable difference, but perhaps maybe the slightest improvement is overall performance.

I have around 86k and had just gotten used to a few hard or delayed shifts when I first started out or an occasional slow or hard shift in day to day use. Saw this thread while trolling and thought I would give it a try. NIGHT AND DAY! I forgot how smooth this truck could shift. It truly feels like a new truck and I had the trans service done at 75k with no big change in performance. Thanks for this post.

I had my 2019 ranger tranny rebuild @ 87k miles. After the break-in period (~1k miles) it still ran a bit rough. I replaced the sensor and things smoothed out nicely.
