Santa Fe P0500 DTC

Santa Fe 2003 LX 3.5L, intermittently getting P0500 (Vehicle speed
sensor circuit malfunction), it drops the speedometer function for about
30 to 50 seconds, then recovers it.
Wheel speed sensors are clean, cables test OK, and there are not missing
teeth on the wheel crowns.

Two questions:

Is there a third sensor (the two wheel sensors + a sensor on the
transmission) ???
I cannot find any, but TSB 04-40-019 seems to imply it (Mention VSS and
WSS).

Does anybody had the problem and know what the solution is ???

Thanks for your time.

The sensor on top of the differential provides vehicle speed
information to the computers and the speedometer on the 3.5. As you
lose function for only a short period, I'd suspect the plastic gear
attached to the sensor rather than the sensor itself. You can remove
the 10mm bolt, pop it out the top and have a look. Usually I replace
both at the same time because it's often difficult to tell which is
the actual problem without trial and error.

Thanks Hyundaitech, will take a look to try to locate it, if that
fail, will order one, after seeing it should be fairly easy to locate.
