The fact that your vehicle presents a correct OBD-II speed reveals that the PCM and the items that feed the required data to it are working fine. On the other hand, it's now fairly clear your speedometer itself has an issue (defective, tampered with, etc). Having a valid OBD-II speed is the proof on this one.
***The speedometer gets the speed data from the PCM, not directly from any sensor.
