I have just learnt something NEW. You nailed it in a few minutes pal. I'm subscribing right away!!! 🥳🎊🎉✨⭐✨🎉🎊🥳

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

That was super helpful especially because I have the same scan tool. Thanks!

Ur a real 1

WOW! Thank You So Much!!!

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.

Is testing the down stream sensor the same method? TY

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?

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

How do you test the downstream sensor?

Test method 80 fail for bank 1 sensor... What does it mean?

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?

There usually is a bigger jump but it did move so likely good.

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.

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?

Pretty sure

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

My reading shows 0.000 for bank 1 sensor 1
