Sandy Point, Texas, just south of Houston | We had this problem on our 8330, a 07 model I believe. Replaced the sensor twice, it would work for awhile and then throw codes and disengage autosteer. Turned out it was the wiring harness to the wheel sensor that runs from the side of engine to the sensor. There maybe a PIP on this check that first. I don't think you need dealer to do this, I don't remeber there having to be a recalibration for this.
