Speedometer malfunction. Unsure if sensor, ecu or cluster. on 1995 Toyota Corolla

If I turn on the key without starting the engine, the speedometer will slowly move to the right until it pegs out. Engine is not giving any error codes, so I don't think it's the sensor. Sensor, ECU or Cluster? Any ideas?

Most likely cluster problem.
