Quick update: Earlier I wrote that I unplugged the crankshaft position sensor and nothing happened. Well, it turned out that that wasn't the sensor I thought it was. (In fact, I still don't know what I was unplugging earlier.) After going over hard to find engine wiring diagrams I finally found the crankcase sensor, and it does kill the engine (and throws a code if I disconnect it while the car is moving). Unplugging only the camshaft sensor still doesn't kill the engine, only prevents it from starting - the ECU synchronizes it with the crankshaft sensor at start up, so if it gets unplugged later the crankshaft sensor takes over.
