He stated
only code I have is a vehicle speed sensor which is for transmission
If the wheel abs sensor is cutting out but not dead then this might cause the vss to give that error since he stated his speedometer drops out at times not that its not working at all.
A good scan tool would find the problem I would imagine one way or the other. I know the one I have would since you can monitor the sensor and it will record drop outs if that is the problem.
