Message	Use the multimeter under the hood on the O2 output (middle wire) and check the voltage while the car is running and warm. You should see the voltage wave between ~1V (usually 0.8) to ~5V with the engine off-idle. If they don't do that (and you verify voltage at one side, ground at the other on the connector) then the O2 sensor is definitely dead.
