2006 TRD Sport ABS Brake issue

My ABS/Brake light is on so I went to O'reillys and had them plug into my port to see what the issue was. They told me that it was my right rear sensor and it had to be replaced. OK, I bought a sensor for it and replaced it myself.....I went and started my truck and the lights are all still on. What else can I do to check into what is causing this? I've heard that the tone rings that are inside the hub can be cleaned up or even have a magnet that can pull out debris that is inside the hub. I feel fairly confident that I can do this myself and not take it to the stealership and get bent over........any help out there guys and gals, is greatly appreciated.

 

Maybe find a good local mechanic and get it checked out rather than guessing?

Just a thought rather than casing the problem
and spending on something it is not.

 

Unplug the battery for 30 minutes and see if that resets the codes.
