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

@georgeh1352 День назад

Good info guys, old style O2 sensor waveforms is just what I was looking for. Thanks

I’ve had my BlueDriver for about 2 years and absolutely love it! Love the links to parts and videos.

Now I know how to read that live data. My #1 sensor needs a replacement. Fantastic video. Thanks!

@sparky1044 2 года назад

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.

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).

@randyb3347 9 месяцев назад

@friguy4444 Месяц назад

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!

@rihovaher 5 месяцев назад

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!

@ramontgillespie5 2 года назад

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?

@magicone9327 9 месяцев назад

When torquing how do you compensate for the offset socket which would change the values of the torque wrench?

@whlawson5812 Год назад

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?

@joebagofdoe4762 2 месяца назад

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!!!

@janosszamoskozi6481 7 месяцев назад

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?

@farmingandmaybemore5175 Год назад

Can this work with 24V type B obd2 vehicles or is there an adapter to make it work with them?

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.

@E85_STI Год назад

@randyb3347 9 месяцев назад

My 2004 ram 1500 hemi purrrs like a kitten in open loop. The moment it hits operating temp and goes into closed loop it stalls. Both upstream sensors are north of 1.2 volts, and both downstream sensors are nearly flatlined steady at 0.8 volts. All 4 sensors were recently replaced with non-oem sensors. Any ideas you may have would be greatly appreciated. Thanks.

@randyb3347 9 месяцев назад

UPDATE: My crankshaft position sensor had failed. Replaced the sensor and it's purrring like a kitten in closed loop.

@chingonr 8 месяцев назад

@@randyb3347 thanks for the update. why did you replace the crankshaft position sensor? did it throw a code?

@randyb3347 8 месяцев назад

@@chingonr Yes, it finally threw me a new code and it was the CSPS. But that didn't clear up my 02 sensor codes. I suspect now it's because when I changed the sensors I screwed up and put dielectric grease on the connectors upstream (not the downstream, I was kind of experimenting). Had I read the service manual first it clearly states to not put any grease/lubricant on the connectors. My wife has been advising me since we met to read the instruction first on everything :) You live and learn....

@desi4lyfe379 2 года назад

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.

@iam1smiley1 Год назад

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.

@desi4lyfe379 Год назад

@@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.

@iam1smiley1 Год назад

@@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.

@bobomomo3764 Год назад

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

Along with your excellent tutorial you need to give about a million other RU-vid 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.
