First time on the site. I recently purchased a 2011 silverado 1500 4WD. High miles, but very well maintained. Soon after purchasing my abs and traction lights came on. Followed by Service traction control and service stabilitrac. My mechanic scanned it and said it was right rear wheel sensor. Replaced on Sunday And drove 15 miles with no lights or warnings. Then they came back on until I got home. Drove to and from work and nothing on the dash.
Does anyone have any ideas. Thanks in advance

 

scan it again
