A Toyota vehicle speed sensor is usually bullet proof. I have never seen a failure but I have seen a lot of speedometer failures. The VSS does a lot of other things besides a speedometer. Does the odometer work??

As I stated before, the odometer is not working as well as the speedometer not working. That is why I suspect I may have a wiring problem between the speedometer sensor and the console. I will be measuring resistance between the 3 wires that go from the sensor connection to the speedometer/odometer. I am not sure what to expect. I suspect I will see a resistance for the speedometer. The 3rd wire may go to a power source, I'm not sure. I was told the power sensor needs power but is not protected by a fuse. That is why I suspect a wiring problem. The speedometer went sporatic(ie bounced around for a few seconds) before it completely stopped working. Hope this helps.

I have replaced dozens of instrument clusters on Toyota trucks and i have NEVER found a wiring problem or a bad vehicle speed sensor. The symptom of an occasional bounce is that of a bad cluster.

One truck I repaired had a corroded connector on the back of the cluster which I cleaned with a pencil eraser but never a bad wire or VSS. That was over a 20 year period. Good Luck
