You guys a living legend’s because you teach us how to try and fix it our self with equipment we can afford (Bluetooth OBD2) and not a $5000 scan tool. I’m having trouble somewhere in the catalyst system and only have very limited funds. THANK YOU FOR THIS VIDEO
After literately hours and hours and hours of reading and watching videos this video really helped me to make sense of how to actually read live data thank you guys
It should be noted that you will want your crowsfoot-type O2 socket to be perpendicular to your torque wrench. Otherwise, the torque that you're applying will be different from the value that you set your wrench to. Also, if you're replacing an O2 sensor, they should already have anti-seize applied to them from the factory. And a final note - if you remove an O2 sensor just to inspect it and plan on reinstalling it, they have a crush gasket (washer).
I Wasted so much time before I found this video well done guys, extremely well presented too, before the O2 sensors on my car where some dark magic that seemed some how to hard to diagnose the errors and check engine light they keep throwing, now I feel confident to tackle the errors with out it just been guess work. Thank you
If you're in the rust belt, heat up the exhaust pipe near the sensor before attempting removal. I actually tore the o2 sensor housing clean off a 2002 yukon trying to remove bank 1 sensor 2.
@@aaronwism how/where exactly do you spray it, such that it actually gets into the threads? It seems that if the sensor is screwed all the way in, there would be no way to get any spray into the threads.
@@tc3imagery it’s called penetrating oil fir a reason. I’ve never seen a o2 without exposed treads and I’ve been turning wrenches ( mechanicing) for 40 years. Spray on the nut facing the threads it will run into the treads. Don’t be stingy with it either!
Hello ! I took my hyndai getz 2008 1.4 petrol .no. 1 lamb from the sensor before the catalyst, diagnostics showed a non-existent very low signal due to which the engine worked very stiffly and you could feel the vibration. I put a new lambda sensor original bosch and checked it with the diagnostic device on the engine running in 71.. .730 Ma was the rapidly changing amplitude of the signal. Although I'm not a professional car mechanic, I managed it, as they say a man from the forest fixed the car, good luck to all DIYers!
Good video Makes me want to buy a bluedriver The only issue I had with the video was that when monitoring the 02 sensors there was no bringing the engines idle up to 2500 rpms? But otherwise amazing video!!!
Excellent information and teaching! Thank you for the great video! One little thing I am laughing about to myself as I watch the video is that for the sake of the viewer (Me lol) you've chosen a car with an O2 sensor right up front where it's the easiest thing to see, find, work on and possibly change out if needed. I want people to know though that almost all (obviously there are a few that are easy) are VERY difficult to find, reach and work on. 16:08 "This sensor is proving to be pretty easy to remove". Wow he sure said that right LOL. They are being VERY polite and smooth. In the real world 95% of the sensors you will have to remove will "prove to be" lol. Al LOT more difficult to remove. A LOT, LOT more difficult. They are so often only accessible from underneath the car and sometimes only through the wheel well or some other strange place very difficult to reach. Sorry for telling the bad news. But the facts are always better to know up front then finding out later when you're in the thick of it. Thanks again for the great video!
I heard about the cars built before year 2006 have different type of sine wave pattern for the O2 sensor. This is due to the ECU not cutting back fuel sufficiently to prompt the voltage to 0.1V for the O2 sensor. Yes, no?
A question for the masters , I have a 2013 M37 Infiniti, code P0151 showed up (O2 Circuit Low voltage) Bank 2 sensor 1 , I went ahead and I replaced the sensor, 40 miles goes by and now I have the same code showed up again + P0131 and after resetting the codes now am getting a new code , which is P1168 in addition to the other 2 codes, please let me know if you can help resolve this issue, thank you.
Could you please advise how the ECU interpret the narrowband o2 sensor produced up and down signal fluctuated in the entire range? Does it averages or pick a value in a specific time?
I try disconnecting a vacuum pipe on my mx5 NB ( pipe from cylinder head cover to intake body) to get a lean reading on my BlueDrive but the engine cut out...
My pre cat sensors swing up and down sharply as good ones should, yet my B1S2 is pretty flat at .47V but my B2S2 is flat at .031v. Both spike up when I rev it. Under .45 is supposed to be a lean condition so is my B2S2 detecting a lean condition post car but pre cat the fuel trims are hoveering around 0. Do I have a bad cat in B2? There is no leaks in it as its one unit and there are no leaks between the 2 O2 bungs. All 4 are new and its on a 2012 Chrysler 3.8 with 136K miles. Thanks
I am confused. With my 2005 Mitsubishi it shows a steady up down for bank 1 sensor 2 but for bank 1nsensor 1 it shows numbers, not a graph. Therenis no reference for what is acceptable for the numbers.
My o2 second sensor voltage is higher than 1. 0 It fluctuates between 1.0 and 1.02 on idle and when i rev up its value goes upto 1.6 What could be the reason?
I got (closed loop) as soon as I turn on the engine, 20 seconds After a cold start How can this be fixed I don't think it can go closed loop this fast. Or can this be normal for some vehicles?
2.9 ohms on 12v is 4.1 amps. That does not seem like a short for a heating circuit. And that also is about 49 watts... again, seems reasonable for a small heater.
Along with your excellent tutorial you need to give about a million other TH-cam people how to present a no nonsense video. Head banging music, fireworks, convoluted graphic introductions and unfunny attempts at humor are nothing but aggravating time wasters.
I wish if I have known bidirectional scan tools before I bought bluedriver. Guys, please save your money & buy a bi-directional scan tool. Bluedriver was good 5 years ago, but it is not a bi-directional scan tool. I had to re-set my TPS after cleaning throttle body and than only found out about TPS reset after cleaning & bi-directional scan tools.
I have 2 good bidirectional tools and still keep my BlueDriver in my pocket. It gives good data but yes, a bidirectional is needed at times but there's also ways to go around them at times.
@@iam1smiley1 I had a SRS light on my 07 civic & Bluedriver misled me to coming so close to replace front collision impact sensor. In fact, that sensor was never the problem.
@@desi4lyfe379 code reading is only part of the diagnostic process. Codes may put you onto the correct problem area but it's still up to the technician to do proper testing before changing parts.....you see this happen a lot with O² sensors!
@@iam1smiley1 There are so many cheap obd2 readers & I dont see the value in bluedriver. It was a great product back in the day, but bidirectional scan tools are just much better.
Guys my fuel status shows (closed loop) just after a cold start. And the fuel trims start showing the readings. I don't understand why doesn't make sense 😐 It should only become closed when heat increases. Not sure if that's accurate or it needs an updated IDK Bluedriver Fusion 2014

Wow, I'm so happy, I purchase Blue Driver. Great video, I feel like a expert from watching. Well put together video. ❤️
After literately hours and hours and hours of reading and watching videos this video really helped me to make sense of how to actually read live data thank you guys
Blue Driver videos are absolutely the best vids on the web. Well done!
Relax guys. I like my Bluedriver and would still recommend it to anyone. I've had mine for about 5 years.
I’ve had my BlueDriver for about 2 years and absolutely love it! Love the links to parts and videos.

I guessed they would be, luckily for me my S1 is right in front and came away easily with an open ended spanner....phew. (Mitsubishi Lancer 2006)
Just a superb video. Thank you for sharing your knowledge in such an understandable format.

Yes had my blue driver over 3yrs not knowing how to use or read the live data !
Wow, very clear and helpful to see different scenarios. Thank you so much for this video!

What are your trouble codes?
When torquing how do you compensate for the offset socket which would change the values of the torque wrench?
I’m wondering the same thing.
Excellent information. Thank you very much.
I love bluedriver scan tool.
Best
Will the OBD2 Scan Tool tell you which sensor and location that is bad for needed to be replaced?
thank you bluedriver for this fantastic video your amazing device reaching Oman 👍🏻
Informative video thank you. How can I share my live data report with you to understand if it is O2 or Cat Convertor?
Hey Ed.. does it matter if I buy a Bosch O2 sensor or an Infiniti O2 sensor?
Thank you. Very detailed and well explained video. Legends
So you guys are diagnosing the o2 sensors while the vehicle is just idle? Just asking is all.
I have a 2000 Chevy Tahoe unlimited. Service engine light pops on from time to time. Will this pull the code and also pinpoint the exact sensor?
Why did you guys stop making videos they were so helpful!!!
I am confused. With my 2005 Mitsubishi it shows a steady up down for bank 1 sensor 2 but for bank 1nsensor 1 it shows numbers, not a graph. Therenis no reference for what is acceptable for the numbers.
02 stratus. 80k miles. Check Engine light just came on. Reader says cat or o2 sensor. I'll start with the sensors... thanks.
Thanks very much this video was informative 👍
Awesome. Thanks.
Hello good info. Checked my pre cat sensor and it was reading over three volts? Any ideas any leads would be great thanks. Got a new subscriber
While idling at full operating temperature?
Gracias por muy buena información especialmente para reparar mi pickup ford
Excellent video !.
What about a P2245 (on a '12 Jeep Wrangler JK)?
Great video!
My o2 second sensor voltage is higher than 1. 0
It fluctuates between 1.0 and 1.02 on idle and when i rev up its value goes upto 1.6

I got (closed loop) as soon as I turn on the engine, 20 seconds
After a cold start
How can this be fixed I don't think it can go closed loop this fast. Or can this be normal for some vehicles?
Normal
Mine goes in close loop within 6 seconds, pretty normal.
How do you know when it’s gone into close loop?
@@scottykilmer3920 How do you know when it’s gone into close loop?
if you have a scantool you can see live data !
Can this work with 24V type B obd2 vehicles or is there an adapter to make it work with them?
These test are at idle correct?
Thank you.
Thanks, this is helpful
Great video. Thank you for making it
Thanx
P0137. Git. Low voktage bank 1. Sensor 1
What if an A/F amp is a negative number ?
Is this chris from chrisfix???
2.9 ohms on a heater circuit? its ALMOST shorted. What does the meter read test leads together?
2.9 ohms on 12v is 4.1 amps. That does not seem like a short for a heating circuit. And that also is about 49 watts... again, seems reasonable for a small heater.
Are you guys done making videos ?
can I use it in Italy?
How much this BlueDriver obd2...
Thanks sir
Does anyone know where's oxygen sensor 1 bank 1 in a mecedes E350 2017? Please help @bluedriver
Mercedes are a nightmare with repairs. Not sure. Everything is customed for Mercedes. Get rid of that car
My thing says my car only supports one oxygen sensor?
7:31 Microdose has kicked in 😅
Anyone else have hard time looking at o2 sensors? 2015 Nissan Sentra
Anyone ever associate a P219A with a bad 02 sensor
Sensor #1= upstream Sensor #2= Downstream
Hands in pockets?
Oh my….
thats outta pocket
