My sensor does not look like that at all, I have one that is on the passengers side, it goes into the back of the brake assembly, it has a hex nut that holds it on.

It has a brake pad material on the end of it. Like a 2 inch plug that goes in and it has a 6mm hex that holds it in to one side.

I put it back together as I don't have a picture of it.

Maybe my 2001 has an older style of sensor?
