    How To Test an Oxygen Sensor with a Low-Cost Scan Tool
    1. Start the engine.
    2. Find the 02 sensor volts in live data or data stream.
    3. Pump the brakes.
    4. The 02 sensor volts should go up, then down, and back to the original state.

    Super clear and helpful video! Is there also a test for the downstream sensor?

    Is testing the down stream sensor the same method? TY

    Is you test on an O2 sensor or air/fuel sensor? I thought O2 sensor voltage was between 0.1 and 0.9 volts for upstream O2 sensor.

    If the actual sensor reading is good, why am I getting a bad reading on the Air fuel sensor heater circuit response malfunction? What causes the circuit response malfunction?

    How do you test the downstream sensor?

    Unless I missed it, you didn't specify this is a wideband o2 sensor. For narrowband o2 sensors this check won't work.

    I have a 2004 Toyota Sienna with the 3.3 V6. At idle, both my upstream sensors will hover around 3.2. When I pump the brakes they will each go up to about 3.5 then go down to about 2.8 then back to 3.2. Does that sound correct?

    My b1s1 stayed at 0.00, it jumps to 0.015 and then back to 0.00. Is this sensor bad and need to be replaced?

    I have a Toyota Corolla 05 i'v check everywhere I can't find the fuel tank pressure sensor i'v Google it and it's not where it said it would be next step is to drop the tank

      It should be on the top of the fuel pump.

      Look for your part in your local auto parts store parts diagrams before taking things apart.

    Mine say -127.000 that means it’s bad I’m guessing….
