P0500 — Vehicle speed sensor malfunction
Generic powertrain DTC · MEDIUM priority for follow-up (not a certified safety rating)
What the code means
A fault was detected in a vehicle-speed input used by one or more control modules.
What you might notice
Inaccurate speedometer; transmission shift concerns; ABS or stability-control warning.
Possible causes — not a diagnosis
Sensor failure; wiring/connector fault; damaged tone ring; network data issue.
Useful diagnostic checks
Compare wheel speeds and vehicle-speed signals; inspect connectors and fault codes in other modules.
Next steps
Fix confirmed sensor or communication faults before relying on speed-dependent systems.
