Well done, I thought this was possible also. I was lucky to find an original sensor on e-bay.

This is really interesting and could be quit helpful down the road. Not sure I ever knew what the MAP sensor looked like inside the ECU. Makes it even more interesting when you hear of people suggesting sticking cotton up there and putting on heater to dry up/clean. Seems a little far fetched to think any strand of material could 1: make it all the way up to the sensor, and 2: do anything in the way of cleaning it.
Looking at this, is there any safe cleaner one can use to spray into the outlet pipe on the ECU to clean these? I know they make specific sprays for MAP sensors but are these different and would break if used?

Would tend to agree after you look at the pics. It would be helpful to remove any build-up in the inlet tube, but not the sensor itself. From what I could tell it was just a MEMS type pressure sensor with a silicone membrane over the top. Without trying I can't say, but something which wont destroy silicone.... and then the heater trick to dry it out afterwards.

Just wonder from your picture of the open sensor, is it possible to replace the silicon membrane to rebuild the sensor?
