EBPS replaced
I replaced the exhaust back pressure sensor and tube today. I was not expecting much of anything from doing it even though the tube, sensor and the part it screws into was totally plugged. I had kind of a deadish first inch or so of go pedal since I bought the truck, after replacing the sensor I noticed that was greatly reduced. There was no feathering I could do which made 1st and reverse kind of bouncy. After all the reading I have done 1/2 says the EBPS only controls the EBPV and the other half say it works with the EBPV and fuel maps. I'm in the 1/2 that thinks the EBPS definitely has something to do with the fueling. So even if you have the deleted ped clean your EBPS.

Nah, sometimes when you unplug the batterys the TPS resets to re learn mode in most gas fuel injected vehicles, which makes them have a touchy pedal until it re learns your driving habits. Not sure this is the case in our trucks.

I seem to think on the SD forum a lot of people are replacing tubes or cleaning them along with using the sensor.
I deleted my tube and sensor long ago, along with the pedestal actuator & butterfly. Just left the sensor plug detached.
I personally had no issues after those mods.
But, I would like to know what the experts know and recommend.

Mine is currently flopping about, pipe was all plugged up as was sensor. Truck has been fine for about 25k since I have owned it.
I read into it on the factory manual, best I can figure it is for controlling the EBPV by utilizing this sensor, the IAT in the box, and the oil temp sensor. No clue on the fueling stuff I have read online, I am chipped so probably irrelevant to me. It also seems like a good place to pop in a pyro!

No sensor. Just a pigtail plug covered & tie wrapped to harness.

The exhaust backpressure sensor has nothing to do with the exhaust backpressure valve. EBPV operation is based on temperature you can unplug the EBPS and EBPV will still work normally, if you delete the EBPV the EBPS still serves the same purpose.

I just did a Google search:
"Ford 7.3 OBS exhaust back pressure sensor function"
There are quotes from service manuals, tuners, experts, Sort of experts, and everyone in between.
The amount of information is staggering.
Great way to spend your night.
I kept finding references to poor MPG with the sensor unplugged. My 400k truck gets 20 to 23.5 mpg at 70mph, depending on the wind direction.
Next year I'm going to do a test and buy a new tube and reinstall the sensor. Heck, I might get 25 to 30mpg.
Every time I read about this topic I want to start drinking again.

I couldn’t get mine unclogged and had to remove it and heat it red hot with an OA torch to burn the carbon out of it. I deleted the EBPV and the only thing I use the sensor for is comparing boost to backpressure. If someone wanted to bad enough they could make a few identical runs using AE or some other scan tool with and without the sensor connected and see if anything changes.
