Do I need one to find out what the problem is? Or is there another way?

Get a scan done to check for trouble codes. Most parts stores provides free scanning services.

Most likely the Vehicle Speed Sensor or its circuitry is faulty. Do not jump to conclusion that the sensor is bad. It could be a loose wire or a bad circuit.

Japanese makes comes with a flash code retrieval for pre-OBD-II models.

Most modern scan tools comes with adapters for code retrieval for these but some are not compatabile as the ECM/PCM are not designed for scan tools as they are like those with sight windows which don't have any scan tool plugs.
