After replacing my front end ball joints, my traction control started coming on by braking a wheel inappropriately in turns mostly. During the job I just pulled the wheel sensors out of the hub but didn't disconnect them at their connectors under the hood. I mean i didnt disturb them much. I measured both s3nsors resistance and they were the same and checked out OK. I pulled the fuse so I could drive it but im puzzled what could be wrong?
