The problem might be occurring on another wheel too. Your shop should be able to put the rondo on their lift and hand-rotate each tire, while checking the validity of the wheel speed sensor signals one by one with their scan tool.
Is there anything unusual with the tires? Are all four the same make/model/size/inflation and close to the same amount of wear?
Does your car use in-tire sensors to determine the tire’s psi? Or does is that inferred from the wheel speed sensors?
