I i have the new one but how would i remove the old one

 

Take out the two bolts, unplug the electrical connector, and pull it out. It's in a really fun position though..... some folks go from underneath, other folks go from on top. Rumor has it, they have alan head bolts, as well as the hex head. (don't recall the size though.) So, whichever tool you have on hand, that you can get in there with..... might need some pliers to pull the sensor itself, if it isn't attached to the bracket any more.

 

I kno were its at but theres no bolts left for it no beacket and stuck about 1/16 inside the bloxk

 

Then it should just pull right out. There is just a rubber grommet holding it in place.

 

Ive pulled and pulled it wont come out

 

Get a mirror, or contort yourself around, so you can see down there. I bet the bracket is still there. That is the only thing holding it in, unless the PO glued it, or some such.
