OBD2 fault code
HighP0500
Vehicle Speed Sensor Malfunction
The code identifies an implausible condition in the monitored system. The component named in the code is not automatically the defective part.
What does P0500 mean?
Vehicle Speed Sensor Malfunction. The engine or vehicle control system detected that a measured value, control response, or communication signal was outside the expected range.
Common symptoms
- speedometer or cruise control malfunctions
- transmission shifts incorrectly
- ABS/ESC or check engine light
Likely causes
- vehicle speed sensor or ABS wheel-speed signal faulty
- damaged wiring, connector, or tone ring
- control module receives implausible speed data
Sensible diagnostic order
- compare speed signals across control modules
- inspect sensors, wiring, and tone rings
- scan ABS and transmission modules as well
Can I continue driving?
Only if the vehicle runs normally; avoid heavy load. If the check-engine light flashes, the engine shakes strongly, warning messages increase, or power drops significantly, stop and arrange professional assistance.
