More than likely if the vehicle speed sensor is ok then we could have a ground issue with the cluster or a grounding issue.

However, how did you test the speed sensor? More than likely this is a speed sensor issue, so we need to check the sensor and make sure there is 12 volts getting to it and then that there is a voltage signal being sent to the cluster on the other wires.

Please see the wiring diagram below which will help with this. Please run through this info and let us know what questions you have.
