This was interesting and enjoyable to watch even though I already know what an O2 sensor is and how to test it... Straight to the point with a simple (but not dumbed down) explanation and a very good demonstration.
Man is nice to watch a video by an articulate man. Not a bunch of uhh's, and umm's. English isn't that hard is it? Lol They say it's better to do it with a candle because it keeps the heat to oxygen ratio more balanced.
The best way to remove the lambda sensor from the cast iron exhaust manifold is to heat the cast iron manifold near the sensor from several sides, if the sensor is broken, cut the wire and carefully unscrew the sensor with a long hex key, if you use a split key, which is more suitable for installing a new sensor, you can turn the edges of the sensor round.
Thank you for sharing .I have 2 question,I tested my 2 white wire from the heater and it read 00 ohms(even when its running),also tested signal and ground and it reads 1 volt,would this be consider as a bad sensor?. I also tested the signal and ground from the ecu and it reads 12.4 volt is this too high?....
Why would it bounce up and down in a sine wave? That seems odd to me. Shouldn't it put out a constant voltage under constant conditions? Wouldn't the sine wave be due to adjusting trim of the engine? Also, I wonder if getting it red hot with a torch doesn't do permanent damage to the sensor. I don't recall off the top of my head, and I'm not sure if you are talking C of F, but I'd think red hot is way hotter than 600 degrees.
I'm sure this website can explain it in far better detail than I can and willing to allow time for haha! autoditex.com/page/lambda-sensor-o2-sensor-21-1.html#:~:text=If%20the%20sensor%20is%20working,will%20be%20around%200.45V.
@@TutorialGenius Hi thank you for answering, replaced MAF, and the injectors too. at idle the long term fuel is -4.688, short term fuel trim bank1: -14.062%, and short term fuel trim B1S2: -%. The car had a P0507 that got resolved cleaning the throttle body but the idling is still bad, and planning to replace it soon. The car has no codes. O2 sensor B1S2 is always around 0.3V, and O2 sensor B1S2 moves from 0.3 and 0.4 V The car is a Sentra 2005 1.8S

Thanks for watching!
The opening explanation of open and closed loop was really helpful! Thanks mate 👍
No problem 👍 Thanks for watching!
looking for a video to test the vehicles wiring harness that attaches to the o2 sensor.

Very good explanation thanks!
Glad it was helpful! :)
You hit on so many details and important points it gave me goosebumps.
I think I need a cigarette now. 😆
hahaha! 😆😆

Thanks! Whatever you have available!
Very good explanation and demonstration information thanks 🙏👍👌💐
Great explanatory video. Thank you
You are welcome! :)

Nice video. It cleared things up for me. Thanks.
You're welcome!
Watch dozens of videos this is clear and easy to understand. 😊 And a great video and sound quality.
Happy to hear that!! :)
I bought four O2 sensors, and two of them test at 4.7 Ohms. Are they good? Thanks for the video.
Thank you for sharing .I have 2 question,I tested my 2 white wire from the heater and it read 00 ohms(even when its running),also tested signal and ground and it reads 1 volt,would this be consider as a bad sensor?.

I have a 5 pin upstream O2 sensor that’s reading 86 ohms. Does that mean it’s bad?
If you measure the other 2 wire (not heater side) in Ohms, what will you get while it's still cold?
Open.
Why would it bounce up and down in a sine wave?

bought a new 3 wire o2 sensor and the resistence is 0.0 ohms.
Is it necessary to remove the O2 sensor from the vehicle or can the test be done with the sensor in the exhaust ?
If you have an OBDII scanner, yeah sure, you can look at the voltages.
I mentioned in the video too
@@TutorialGenius Thanks! I found the problem... bad connection at the O2 sensor. I cleaned the connector and working perfect !
Hi, what about a car with a rich condition, and the o2 is always about 0.285 V to 0.305 V?
Do you think the O2 is faulty?
oxygen sensor, MAF, fuel injector leak, vacuum leak, fuel regulator.... many things! What are the long and short term fuel trims saying?
@@TutorialGenius Hi thank you for answering, replaced MAF, and the injectors too.
at idle the long term fuel is -4.688, short term fuel trim bank1: -14.062%, and short term fuel trim B1S2: -%.

The car has no codes.
O2 sensor B1S2 is always around 0.3V, and O2 sensor B1S2 moves from 0.3 and 0.4 V
The car is a Sentra 2005 1.8S
Hurry up a show😂
You talk too much dude. Get to the point
Here's the door, 🚪 use it 😊
Omg only test 1 sensor you're talking so much bro ur suck video bro
That's why we have teachers and McDonalds workers in this world. You have chosen your path already
Please stop moving.
I like to move it move it
You talking so much bro
