A: The only way to know if the O2 sensor is functioning normally is to. Check its responsiveness to changes in the air/fuel mixture, by Voltage Measurement or Wavefor m Simulation. Use a 10-megaohm digital voltmeter. Hook up the voltmeter's red probe to the sensor's signal wire and the black probe to engine ground.

Use back probe method, DO NOT pierce the wire. For a good sensor, voltage should fluctuate constantly between 0.1 and 0.9 volts after starting the engine for 2 or 3 minutes. Oes above range between 0.1 and 0.9 volt r emains below 0.5 volts Stays fixed at a particular voltage. Upstream location is between the catalytic converter and the engine. N is between the catalytic converter and the tailpipe.
