I have a 2007 Tahoe with the ABS light on. I know this is usually the front sensor problem so I went ahead and replaced them both. The light was still on. I even swapped the new sensors to make sure. I also checked under the seat to see if connectors were loose but they are not. Can anyone give advise on what other possibilities this might be?

 

ABS codes need to be read. That's step one, codes will point you in the right direction. Otherwise your just throwing a dart and cash hoping to hit the target.
Today you read the codes before even opening the hood.
