I just had the rear Ant-Lock Brake light turn on, what causes this? Is it just a bad sensor?
Junk yards and craigslist. Do you know if its your sensor, or are you just replacing it because FOG suggested you should...?
Also check rockauto.
Don't just change it because you THINK it is bad!
Good luck finding one at a junk yard. I have been looking for one since March and have yet to find one. Check the whole rear brake system as well. The Factory Service Manual can be very helpful.
