Must Know Before Buying:

A: The only way to know if the O2 r is functioning normally is to check its responsivene to changes in the air/ mixture, by Voltage Measurement or Waveform Simulation. Use a 10-megadigital voltmeter. Hook up the voltmeter's red probe to the r's signal wire and the black probe to engine ground. (Use back probe method, DO NOT pierce the wire.) For a good r, 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 r: 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 if our r fails to work, in this case.
