Must Know Before Buying:
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 Waveform 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.
Please take a video clip of the voltmeter and contact us if our sensor:
Goes above range between 0.1 and 0.9 volt
Remains below 0.5 volts
Stays fixed at a particular voltage
You’re free to choose replacement or refund if our sensor fails to work, in this case.
