I have to admit it did make it a little bit better in a sense.
2 weeks later of having an occasional issue or new issue (the let’s just skip 4th gear entirely) made me head for the dealer before my warranty expires.

Steve,
Thanks for having the TSB handy. Dropped Danger Ranger off at Woody Anderson Ford in Huntsville, AL this afternoon to get looked at.
Truck is 4 years, 11 months old (2019) with 58,000 miles. Under warranty still? Yes. ?
Even though I have changed the DPFE sensor, MAP sensor, and IAT...
Not my photo but we do have the two piece lug nuts.
They look nice, but it’s Ford cutting some manufacturing cost corners. The outter layer is what swells over time and makes it where not even a SAE 3/4” socket will fit. In my video you can see me able to almost rotate that outter layer...
Good tip. I always check Ford Parts or Levittown first. I know Woody Anderson in Huntsville, AL is legit because I needed to replace a swollen wheel nut and it was the exact price as online.
Hoping the $150 I spent on sensors prevents that. :crackup: It did fix what I thought was the transmission going out for now..
Closing in on 60k miles so the clock is ticking. I did buy the 7 year/100,000 miles warranty with the truck from my dealer though so at least there’s that.
Drives like a brand new truck.
I theorize it takes a few days for everything to relearn, and the janky 3rd to 4th gear symptom is at least 95% smoother now. No more lugging or the feeling the transmission is in too high of a gear going 20 or less mph either.
Took a sledgehammer to my bucking/surging issue, the terrible 3rd to 4th gear shifts, and lugging at lower speeds through my neighborhood.
I am an electronics manufacturing engineer so I know sensors do not last forever so it was an age of my truck (about to be 5) and piece of mind too.
Plus...
Greetings All,
Dropping another one of my write-ups. This time on our Intake Air Temperature (IAT) sensor. (Also known as a Air Charge Temperature Sensor)
When I was working on my bucking/surging issue by replacing the DPFE (Differential Pressure Feedback) sensor, I figured why not go ahead and...
I thought I might be a guinea pig; see if the fix lasts longer than if you only replace one.
My new IAT arrived today too..$17 so why not.
I figured you could not go wrong replacing the big 3 (DPFE, MAPT, and IAT) every 5 years or so (my Ranger is a 06/19 build date).
Greetings All,
Dropping another one of my write-ups. This time on our intake manifold MAPT (Manifold Absolute Pressure & Temperature) sensor.
When I was working on my bucking/surging issue by replacing the DPFE (Differential Pressure Feedback) sensor, I figured why not go ahead and change the...
Just changed the thread title to reflect this is an EGR related issue to avoid confusion.
That is really good to hear you have had success. I think the biggest question everyone has is how long will the new part last, hopefully longer than the factory part. :crackup:
If yours does go out again...
There are quite a few components of our truck’s EGR system so it could be any of the hoses or tubes in the below diagram. I do think there is enough data to say when we replace the DPFE assembly (like in my write-up) it fixes the weird issues.
I would go ahead and replace the entire assembly...
Differential Pressure Feedback Sensor.
Based on that description you have it would appear to be this exact same sensor. Mine did not give me a code or anything yet ; has yours ever been changed?
