Use either an analog VOM or a lab scope set for either Volts or Ohms to look for a smooth sweep as you slowly move the throttle from open to closed several times. Any jumpiness indicates a bad sensor. Voltage should read at spec for minimum and maximum at WOT and closed throttle, but any variation means little until you check for reference voltage and ground.
A digital voltmeter, ohmmeter, or multimeter is worthless for this purpose as the resolution will not catch a problem. A graphing multimeter is similarly not usable.
