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
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?
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?
Hi, thank you so much for all your videos…two questions, will this test work the same on American cars? I have a Chrysler Town & Country, my 02S11 reads less than 1V (as low 0.175 and as high as 0.840) when I press the brakes 5 times nothing happens, my 2nd question, if it does not go up, then down, then back to what reads for me, then the 02 sensor is bad? Is just that I’m getting a P219A and a misfire to cylinder 3, so I change sparks and ignition coils, PCV, check all the injectors, everything looks good but the P219A and misfire continues, so I think I will change all four 02 next. Any information or answers to my questions will be greatly appreciated. Thank you again for sharing your knowledge through your videos. They are all super helpful.
Super clear and helpful video! Is there also a test for the downstream sensor?
I have just learnt something NEW. You nailed it in a few minutes pal. I'm subscribing right away!!!
🥳🎊🎉✨⭐✨🎉🎊🥳
Nice trick to force lean from inside the car! Thanks.
That's a good video. wish I watched it before I ordered a sensor for $60.
Thanks for your concise explanations!
That was super helpful especially because I have the same scan tool. Thanks!
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.
I think it varies by manufacturer. I work on ford's and their operating voltages for 02 sensors are 0.1-1.0 volts
Mine is at 0.2/3 at idle and cold engine and 1.8/1.9 when its at temperature.
Is testing the down stream sensor the same method? TY
Thanks, everything helps with these expensive damn sensors...SUBBED

It should be on the top of the fuel pump.
@@HVAC_Mechanic it's not it's not on the tank or the charcoal canister or the fuel rail
Look for your part in your local auto parts store parts diagrams before taking things apart.
Is different lambda11 and osb1s11?

There usually is a bigger jump but it did move so likely good.
Same
I have a 2012 Scion tc, my o2 sensor voltage is always under 3.300, does this means it’s bad?
Test method 80 fail for bank 1 sensor... What does it mean?
WOW! Thank You So Much!!!

It needs to be diagnosed, but I would fix the misfire on cylinder #3, as that is likely the cause of the P219A code.
@@HVAC_Mechanic Right, well at least I know is not a spark plug, ignition, pcv, or injectors…so I will continue on the process. Thanks for your reply.
How do you test the downstream sensor?
I just changed my 02 sensor. But after 200 miles sensor is still the code. What can I check for running lean diagnosis
Vacuum leak. Carb fuel. It’ll be okay if you spray little
Unless I missed it, you didn't specify this is a wideband o2 sensor. For narrowband o2 sensors this check won't work.
Help me I have p0171 code for corolla. 😢
I made a video on how to troubleshoot a P0171 Code. Here is a link. ruclips.net/video/b9__WGuD-dc/видео.html
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
Ur a real 1
Mine say -127.000 that means it’s bad I’m guessing….
My reading shows 0.000 for bank 1 sensor 1
