Thank you. This video really helped and explored my knowledge to determine quick to which o2 sensor is fail via live data test by a scanner.

[@PoLarBear_1973]

Thank you very much for such a clear and concise video.

[@mattmotionpix]

Great explanations, and taking the time to show the live readouts and sensor activity... is so insightful. I love my BlueDriver reader paired with the android app for observing these exact conditions with live telemetry on my big express van, which throws these faults sometimes. And sometimes, it's just old touchy wiring (that I probably will update at some point).

Thanks for explaining that bank 1 is nearest the front of the engine. Good info!

Cheapest decent OBD2 scanner I've found, is a cheap (Bluetooth) ELM327 OBD dongle ($5.00) and the phone App (Car Scanner Pro-$5.00). It gives LIVE data graphs and plenty of features. I used to have a $2,000 Matco professional unit, but it expired in 2001, so I needed something quick and simple. This is good for now.

Really well explained, thanks!

Thanks alot for lovely vedio, but what if I have OBD1 lexus LS400 95 model, and I get the Bluetooth OBD2 & installed paid app , but not working with my LS400 ( works fine with other newrs cars ) What should I do to know the error cods check light in my LS400 95 🤔

[@kalpeshkapadia4623]

Thanks sir

[@georgeh1352]

Good job, Checking my S2 at the moment. Reading is varying at 0.1+/- 0.05mV so assuming good sensor, think CAT needs a clean.

[@wilhelmmmitlwe2800]

Thanks

[@ps4account674]

Thanks that was a great way to see what's wrong, I'm trying to troubleshoot for the longest time a P0420, some say is either the oxigen sensors or the catalytic converter, you think if I get that reader, I'll get some good live data info besides the ox sensors? What other live data could help me with my code? 🙏

[@binovc9108]

I have a 2002 Dodge Grand Caravan 3.3, which is a V-6, and it only has two O2 sensors, 1 upstream, 1 downstream. Otherwise, thanks for the good info. Trying to figure out why I started out with a P0135 code (1/1 heater performance), and after replacing the Bank 1 Sensor 1 (upstream) sensor, I now also get P0134 code (sensor circuit no activity detected B1/S1).

Question I have a 09 crv got code po 420 went connecting OBD for live data I get my numbers just don’t stay steady like on your obd I get 0.191 the 0.054 then - 0.031 is the a bad sensor ??

[@mikaile9954]

Hello. I saw your video about the oxygen sensor on KZbin. I have it in my golf mk5 car. Bank 1 Sensor 1 values are 5.29 mA. However, you said it should be between -2 and +1.5. Do you think 5.29 values are normal? Engine light is on. I'm not sure about the sensor's work.

[@eddievantailn2882]

Do you know if VW or any car trouble codes are recorded by the vehicle ?

[@monstermind4286]

I have a toyota camry 2018 se 2.5l I have misfire cyl 2. Code and also random misfire I believe p3000 I have new fuel pump and filter. New Injectors.. new spark plugs. swapped coils to check if it changes to different cylinder code. Checked leakage for valves. Good. Intake sensor good. MAF sensor is good. Haven't checked compression. But when I disconnect cylinder 2 while misfiring it doesn't change meaning seems that exactly still the area where the problem resides. All others (1,3,4) when disconnected cause it to misfire even more.. I do also get engine power reduced sign on dash. May my 02 sensor for any faulty reason possibly be causing my ECU to think it's running rich or lean and be causing the random misfire and the specific cylinder 2 misfire?? Without popping up a 02 sensor code on OBD 2 scanner??? Thank you guys any help would be amazing!

[@ElVerdeVida]

Hope someone can help. I have a uaz hunter and was running normally then suddenly the vehicle feels like.. if gas has dirt on it... and it shutsoff then start again and it feels like.. like again like if dirt was on gasoline and shuts off. I already bought a new oxygen sensor which i think it is. Any recomendation or comment on your experience ?

[@user-pt5nx1np5t]

This car has 2 upstream wideband sensors (they read current) and 2 downstream narrowband sensors (they read voltage).

[@thomasmunguya2207]

Does this mean I can’t read the voltage for the upstream sensor?

[@chicagorc3967]

the tool you used was 170$ man but the tool in your link is 40$? how can you say that other one will work if you didnt use it?

[@yourecancelledfromsociety7551]

You can get live data from your vehicle for even as little as $20 with the right setup. Doesn’t need to be expensive to get what you’re looking for
