Drive on a freeway or highway where there's a speedometer check point. Set your odometer to zero, drive the exact speed limit (try to use cruise control), and after the speedometer check point is over (5 miles), you will be able to determine if your speedometer is working correctly based on the miles driven according to your odometer and the end of the checkpoint.
If the speedometer/odometer is working, chances are the VSS (Vehicle Speed Sensor) is good.
You gotta smack it with your shoe.
This code indicates a problem with the vehicle speed sensor. Check the wiring and if it is good replace the vehicle speed sensor.
Check out a good Public Library.
Check
servis control
Replace the faulty speed sensor and the light will reset itself after a short drive.
if your code is po500 check the wires between speed sensor and cluster .mostlikely your problem is in the cluster
I started having tons of electrical problems and they told me it was a speed sensor. I. Would suggest you check for an oil leAk.
Probably the wheel speed sensor. Check the connector. If connection is good then the sensor may have been damaged or it has failed.
check for a faulty speed buffer module
Check the speed sensor on the top of the tranny. This will tend to build up with metal shavings and cause the sensor not to read the speed of the transmission.
