The sensor is wired to your "diagnostic plug" inside the left fender. In your car, it is completely unused unless some sort of diagnostic tool is plugged in.
It's a pain to get to, but if I were you I'd simply verify that the sensor bracket is securely attached and there is clearance between the pin and the sensor face.

Hi Bob
Very helpful information!
I spray painted the pin so as to be able to tell if it is still scraping. The leading top edge of the pin does have a bevel - not sure if it has worn that way or not. Everything around the sensor is packed with dirt/grease - very hard to see what's what - I'm working on getting that cleaned up before I crank the engine.
Could you direct me to pics or a diagram of the sensor? How is it held in place and is it adjustable?
Thanks,
Joseph
