Good afternoon,

Does anything else not function?

Does the transmission work correctly?

The sensor has no voltage to it. It generates a voltage to the ECM.

Okay, good chance the dash cluster itself has failed internally.

To confirm, I would have someone with a scan tool see if they can monitor the speed on there scan tool.

If they can, the cluster is bad.

If they cannot, it sounds like a wiring harness issue.
