Footnotes

  1. Value may vary due to altitude and weather.
  2. O2 Sensor will toggle from Low to High every few seconds.
  3. Pre-catalyst O2 Sensors will toggle from 0.0 volt to 1.0 volt when operating in closed loop.
  4. Post-catalyst O2 Sensors should remain near a fixed value.
  5. Value may vary due to ambient air temperature.
  6. Value will change due to fuel level change. Voltage will increase as available fuel decreases.
  7. Will vary due to fuel level and ambient air temperature.
  8. Can be different due to vehicle option.
  9. Value is application specific.
