Well, since it apparently isn't a sensor problem, I now have a spare sensor on hand for any future use.

I just don't know where to go from here. I wouldn't even know where to start to check the wiring. I'm considering taking it to a dealer for a diagnosis, but I hate to pay what they'll want just to check it out.
