Thank you for explaining that. You just saved me a lot of money. Initially I was going to replace all 4 sensors in my ford truck but I did not realize that the dow stream sensors were specifically for the catalytic Converter. My truck recently started shutting off in the middle of traffic, so more than likely just my upstreams need to be replaced.

[@lewisvogel466]

I just replaced both 02 sensors in my Toyota Tacoma yesterday. I had the upstream sensor in for 14 years and the downstream in for 11 years. Man, what a difference in my engines performance. Everything runs so much more smoothly like i just got a major tune up. 485 dollars, but money well spent.

[@RBTheMechanic]

Nice job!! Yup it’s makes big diffrence !!

[@TheSouthParkVidsFTW]

Very helpful at the least now i know i will only have to replace the o2 sensors before the cat.

[@usnchief1339]

Great job! Thank you!

[@antor.j.medrano]

the thing about it is, is that was explaining my best friend & good friend & black cousin how this works. NOW I can send this video to them.😀

[@RBTheMechanic]

Lol yeah

[@bigred5393]

Thank you 🙏 my man I love ❤️ the way you explain the concept ✅🥰🇺🇸💯

[@RBTheMechanic]

Welcome!!

[@markmaushil2431]

Nice explanation 👍

[@RBTheMechanic]

Yup thank you!

[@vahagnmelikyan2906]

If I add hho from air intake filter box, will that throw off the sensors?

[@RBTheMechanic]

What is hho

[@vahagnmelikyan2906]

@@RBTheMechanic water electrolysis Positive negative on still plates they turn water into hydrogen and oxygen. What will happen if I inject it through air intake.?

[@ttautogarages]

Great explanation

[@RBTheMechanic]

Thank you

[@vahagnmelikyan2906]

What will happen if air intake is mixed with hho(hydrogen +oxygen)?

[@RBTheMechanic]

Not sure I never tried

[@Shamarihindsbmx]

Heck yeah i get some understanding

[@superdostrese4380]

The o2 sensor does not sense outside oxygen… just what’s inside the exhaust.

[@RBTheMechanic]

Yes

[@smashertechq8463]

Can it detect mafra in it

[@RBTheMechanic]

No

[@DARRENJOHNHARRIS1]

Can you bypass the 02 sensors

[@RBTheMechanic]

No I wouldn’t recommend it

[@DARRENJOHNHARRIS1]

I thought not can you help I have a 2016 Nissan QQ 1.6 Petrol. I replaced the bank 1 sensor 2 12 month ago this sensor failed again code P0138 H02S2 and P0037 I have a reading of 1.79v reading on the diagnostics H02S2 and it’s running rich. Before spending money on another sensor can you help with what’s going on like I said the sensor was only replaced a year ago could this be a dirty cat? Also do you have any recommendations on cleaning the cat without having to remove it I have been reading people have been putting Lacquer Thinner in the tank ??? thanks for your reply I look forward to hearing from you cheers

[@RBTheMechanic]

@@DARRENJOHNHARRIS1 sensor could have failed before u do anything u need to replace that sensor also there is a relay for sensor replace that also

[@DARRENJOHNHARRIS1]

@@RBTheMechanic is it normal for a sensor to fail so quickly they are not cheap and I don’t want to keep replacing it every 12 month. Should I replace both bank 1 sensor 1 and bank 1 sensor 2 ? Is it possible you can give a little more information on your reply to my original question I can’t find the location of the relay only a fuse to the o2 sensor I appreciate the help but I am no mechanic more help please 🙏

[@RBTheMechanic]

@@DARRENJOHNHARRIS1 usually they last good 2-3 year but u never know defective

[@Alwaysbusy300]

Thanks. I understand the oxigen s it's there just. Manipulate the fuel and make the car rum on the computer mpg especified from the Manipulate car market, that say if the car can give 50miles per gallon the ecm will make more fuel into the exhaust then all the. Energy waste on the donw pipe its burn at catalytic converter try to give less contaminated air out , or just say car its eating the fuel accordingly to the monopoly and that it's how its done into the computer control, and the cat. It's there just to burn the remaining fuel, and u don't smell the raw fuel coming out of the exhaust otherwise u catch back ad more oxigen and re-burn entirely end use the energy that it's waste at cat. By the. Way cat I control automakers treason

[@parksphakwa8871]

I have a pajero it can't go beyond 4000prm it will misfire It also consumes a lot of fuel

Sorry idk what u said

[@helpAmerica1]

It reads CO2 not O

[@82ndabnveteran]

It would be called a CO2 sensor then not a O2 sensor.

[@WarmthRainThunder]

My boyfriends car started having error codes ( p0300, p2626, p0132, p0130, p0030, p0302, p0441, p0304) Which I’ve ruled out was the 02 sensor or ECM being bad. He’s literally on the way to his next command (military) and his car broke down at midnight. It sounded like the engine was misfiring and shaking, would go above 40 when driven to the closest but closed mechanic shop. I don’t think it can be anything else but those 2 things. Hopefully it didn’t damage the engine. It had a high meaning, not enough oxygen. And it’s an error before the catalytic converter. Or an error on the ECM and just fucking the engine up…. Huh….

[@RBTheMechanic]

What year make model is the car

[@WarmthRainThunder]

@@RBTheMechanic 2015 Hyundai Sonata. The mechanic saw it and it was indeed the 02 Sensor and he was back up and running by 11am. It was causing his engine to misfire :D Thank You!
