just a note: if you click on the "buy parts" link at the top, it will take you to the store run by the owners of this site. They list the sensors for about $136 each. And they get the parts to ya quick! Other places have simliar prices. heck, you could probably call the dealer and get a decent price if you only like to do things that way. I'd still clean the sensor and tone rings first, before I spent any money on parts.
