wheel sensors

[Little General]

What the deal with wheel sensors. I have not had a failure yet but a friend in the Hummer Club said you can clean them. I know in the past service records there were serveral replaced on my H1 before I bought it. What should I look out for?

If they go bad you will get ABS/TT4 codes. There is a way to jumper them and push the crud out, but I dont remember exaclty how you do it.
