DTC P0500: Vehicle Speed Sensor: Description
WARNING: This page is about a different car, the 2002 Nissan Maxima and 2002 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.
The Vehicle Speed Sensor (VSS) signal is sent from the ABS actuator and electric unit or ABS/TCS control unit to the instrument cluster. The instrument cluster then sends a signal to the ECM.
