I thought the hot film looked like a chunk of black plastic.....been awhile since I looked at one. What the oil does to it is "contaminates" it, that's how I heard it described. And it's pretty delicate, it surprises me that you say you "decontaminated" one. I heard once they bite, they're junk, I guess I said that already though. Even a leaking air intake is said to damage them, just little pits from being hit by dirt particles, very sensitive to "anything".
The old injection systems used a "hot wire" sensor, and these were more durable, but not as good, I guess.
They used to use a intake manifold pressure sensor, and couple that with a barometric pressure sensor and sort of get info they wanted, but mass air flow is pretty much the industry standard right now, I thing intake manifold pressure, for a natural aspirated engine, is pretty passe right now...
