"I have become convinced that fully 97% of the Ford technician training program is centered around how to disconnect all the stupid clips and clamps used on these trucks. I don't believe I've seen any two electrical connections that work the same.
Anyway, rather than cleaning the old sensor, I simply ordered a new one with the idea that I will clean the old one at some point and then swap them back and forth every 100,000 miles or so in the future.
When I pulled this one out, I was expecting dirty, but got a bit of a surprise:
Most of the soot got wiped off while I struggled with that infuriating clip. I'm still not sure how I got it apart!
Anyway, thought I'd share since this exercise was prompted by some of the recent threads here.
SB make a MAP spacer that in theory moves the MAP sensor out of the path of the soot oil spray. I install an SB space a few thousand miles ago and an interested to see if it really works.
another thing I did was install a amsoil bypass filter to remove larger than 2 micron particles from the oil. I’m hoping with less soot particles in the oil…the oil spray whiny carry as much heavier larger particles that collect everywhere along the pathway of your intake. Once I do an official intake cleaning using a diesel intake cleaning product…I can revisit to see if this by pass filter helped at all.
I kept my old map sensor and ultrasound cleaned it with official ultrasound cleaning solution and let it sit out to dry. So I have a spare in case the installed one needs to be cleaned.
I've seen that spacer advertised and thought about getting one myself, but ultimately decided against it. On the one hand I can see how it could work, but on the other it seems to me it would clog up the same as my sensor has. I'm thinking the only real solution is to clean the existing sensor every 50 to 100 thousand miles.
I plan on cleaning this one and keeping it as a spare, too.
I found my notes; I cleaned my MAP sensor at 87474 miles in March last year after Fritz posted a thread after he bought the S&B spacer. I now have over 106k miles.
Found the pics...

Reason: correct post
Before photo some carbon build up. Scraped lightly with knife, sprayed with cleaner while holding it upside down so fluid would run out. Wiped outside with paper towel, after photo nice and clean. Reinstalled. 60k miles on truck.

Yours has less mileage than mine when I did it and the hole in the carbon build up is bigger than mine... mine was almost closed up. But yours seems to have had a higher build up on yours than mine.
Mine seems like it had a thinner layer of build up...
The hole wasn't blocked at all just build up on the top area. Not moist at all either, completely dry. The carbon easily flaked off with the knife. Gave it a couple good sprays, wiped the dirt off the outside plastic.

Thanks for sharing...
You may want to investigate further to identify the source of your moisture (i.e. water/air cooler, PCV box)
On the one hand I can see how it could work, but on the other it seems to me it would clog up the same as my sensor has.
Funny that you posted this, I was just thinking the exact same thing this morning. The only thing I could come up with is that the hole in the spacer appears to be larger, so it might take longer to clog. Less frequent cleanings could be the advantage. I may send S&B a brief message to see what they say. I haven't been able to find much in the way of user feedback on the forum.
