What does P0500 mean?
P0500 — Vehicle Speed Sensor Malfunction. This is an OBD-II diagnostic trouble code a scanner retrieves when your vehicle's computer detects vehicle speed sensor malfunction. The level of risk depends on how the vehicle is currently running and how long you've been driving with the light on.

How to fix P0500
