You made two mistakes........ Do not scrape the sensor, and use MAP/MAF sensor cleaner ONLY. Hold the sensor with the hole pointed downward and spray the MAP cleaner spray on the bottom and inside the hole allowing the cleaner to drip back out as you are spraying. I used an entire can of MAP sensor cleaner to get mine clean without any scraping.
Yep, what he said... MAP/MAF sensor cleaner only. I gently used a Q-tip I believe for the hole... real gentle like...
Is there really that much difference between MAP/MAF cleaner and GDI cleaner? Both are cleaning the same thing: carbon/soot deposits.
Oh well, guess I learned an $80 lesson. Going to town to pick up the new sensor now. Motorcraft was $111 and AC Delco was $75. Ouch.
Its not the carbon or soot to worry about.....its the plastic housing, circuit boards and small electronics that can be dissolved or melt from the other types of cleaners.

But, GDT/turbo cleaner (the one I have is CRC brand) is designed to be sprayed into the intake. Intakes are plastic, MAFs are plastic, intake manifolds are often plastic.....
The more I think about it I believe my mistake was gently scraping the soot out. The tool probably damaged the sensor inside. I noticed that the Standard Motor Products brand I bought today has a barb inside the sensor to prevent any tools from being pushed inside.
Well, I've had the sensor installed and batteries unhooked for a few hours now. Time to reconnect power and pray that the engine runs normally again....

It has nothing to do with plastics its all about the sensitive sensor inside that cannot have any residue on it. There are only 2 acceptable cleaners both from CRC
@wrvond that stuff on yours is really oily... I'm thinking my catch can is helping me with my intake as my MAP sensor looked more like the others with a more dried, caked on build up...
When I removed the hot CAC hose to get the FRP sensor for the Derringer harness connectors, there was not a lot of oil... I can't remember if I cleaned it out when it was out when I installed the S&S DPK kit recently... I don't believe it stops everything but does catch the majority of the crap though...
from your post on that thread, #25.
I just recently bought the electronic cleaner, so it's good to know that when I run out of the MAF sensor cleaner, I can use the other stuff also...
My MAP looked identical to your first pic, just a pinhole visible. I changed the old sensor out with a HITACHI sensor (OEM manufacturer) and I have gained 5lbs+ of boost at WOT. Where the truck normally tops out at 20lbs now hits closer to the 30lb mark on the gauge. Fuel mileage gain unknown as I just replaced the sensor a few days ago. I will try and report back when I have ran through a few tanks of fuel.

Did a little maintenance this morning of changing the air filter and replaced the MAP sensor. I did notice that when replacing the old with new looking down the hole of the old sensor I could not see the wire at the bottom of the hole like I could clearly see in the new MAP sensor.
I still on occasion get an "P259f Turbocharger 'A' Boost Control Position at high limit has been detected" and the MAP sensor is a possible cause. I'll see later if I run for some propane and stomp on it.
