I do have a triangle yellow light hazard shown in the in the upper middle of the speedometer. Does that mean I have traction and if so do I need to replace the wheel speed sensor with traction? Any response or comments is greatly appreciated.

Im pretty sure it could be a fault with the tone ring on the rear axle, just as likely as a fault in the sensor itself, and you'd get the same fault on the scanner.
Unless he tested the actual sensor with a voltmeter, it would be hard to know which problem it is
