P0500: Vehicle Speed Sensor Malfunction
System: Vehicle speed · Priority: medium
What P0500 means
The control module detected a condition matching the generic definition Vehicle Speed Sensor Malfunction. A trouble code identifies what the module detected; it does not automatically identify the failed part.
Useful next checks
- Compare wheel/vehicle speed PIDs with actual vehicle movement.
- Inspect speed-sensor wiring and connector.
- On many vehicles the speed value may come from ABS, so scan all modules before replacing a sensor.
Why vehicle context matters
The same generic code can have different diagnostic paths depending on engine, calibration, wiring layout, service bulletins and related codes. Freeze-frame and live data can help establish when the fault occurred.
