Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
This can happen when one of the wheel bearings start to fail or of a harness is damaged which would usually happen on front wheels. At this point you will need a scan tool connected capable of monitoring sensors during problem and whatever sensor is giving inaccurate reading check that wiring, if good replace that bearing which has a wheel speed sensor built into it. Let me now if you have more questions or if there is anything else I can do to help. Thanks.
