i replace o2 sensor still pop up the same code solutions.

[lowdown]

I’m having the same issue. I ordered a bank 1 sensor 2 02 sensor. Found this video and you confirmed that would be the fix. Thanks.

I had code for o2 sensor on an 04 honda civic lx. Replaced it with a 'delphi' o2 sensor and it seemed to run better, but had occasional hiccups, and started throwing a different code relating to the o2 sensor. Checked with multimeter, wiring was fine, plugs fine. Reluctantly, on the advice i found in forums, I replaced it again with OEM sensor (denso) and it actually worked. According to the forums, the other brands won't send just the right signals that it's expecting to get the way the OEM Denso sensor would.

Thanks for sharing this my friend.
I was having issues with my car, cel light on and codes p0132 and p0152, it was driving me crazy, I never thought that the rear 02 sensors would be the cause of the problem.
You just saved me lots of money, time and headache.
Highly appreciate you. Thanks 🙏.
Oh, and I was already subbed to your channel.
Just like it.👍🏻

So frustrating. Something that should be easy (replace an O2 sensor) and it turns into an endless battle....

*Imagine changing a whole exhaust system, all 4 o2 sensors ( twice ) and come to find out it was a vacuum leak*

Thank You for sharing your advice and experience. You are helping many of us out here. God Bless You 🙏

Wow, I am having the same problem with my 05 4runner. I had change my driver manifold including a new upstream o2 sensor and it is throwing p0031/p0051 code from both bank 1 and bank 2. I will try changing out the 2nd o2 sensor to see if it works. What a headache.. thanks uncle. I'll try it.

My 2003 Ford Mustang keeps throwing P0153 for Bank 2 sensor 1 slow to respond. I replaced upstream with a Ford Motorcraft O2 sensor. The code still came back. I don’t have cats and using MIL eliminators. I’ve been to the exhaust shop twice to check for an exhaust leak, and now you are making me think I may wanna check my downstream O2 sensor since it’s the original with 131, 000 miles.

FYI ... I found out today that accidentally leaving one of the hoses on the intake near the air filter disconnected after changing the air filter will throw the exact code for this bank1 sensor2 O2 sensor failure

my torque app said the light was on for 'o2 sensor slow to respond' ... instantly fixed by fixing the disconnected hose on the side of the intake tube

if you have this code for bank1 sensor 2, first check all of the hoses that attach to the intake before digging into this O2 sensor repair - especially if you've recently had the air filter out

if writing this helps at least one person it's worth it

Thanks for sharing this! I’m having this problem right now with my 2009 G37.. will try this asap and see what happens 🤞🏼

[imjustabartender]

I’ll check that tomorrow. I just replaced both up and downstream o2 sensors on my matrix xrs and the engine light came back on. I have a second xrs. 😂 ima swap the coils and see if that works. 👍

[chriskourlos]

Thankyou i believe this is my problem. Im gonna show my mechanic at auto electric shop cuz I cant get anyone to figure it out yet. My car bank 2 sensor 1 check code check engine light on replaced it twice after transmission renewed 2 mis ago from dealer.
I hope its just a faulty ignition coil stinking up causing the sensor to pick up stinky and check engine come on.
Thankyou. Where is your shop? Maybe I come to you if after this only gets reset and check engine comes back on.
You have made sense and im not depressed and not anxious. Much prayers now.
Wish me luck brother!
Great upload. Please do more.

[paultran]

Thank you so much my 2001 avalon had same thing 02 sensor both in bank 1 replaced but same code came right back up .

[DaKidMel]

I dont even know how i came accross this video but i have a 05 4 runner with same issue throwing p0158 everytime even after cat and sensor was replaced very informative ill check on those coils and swap 02 sensors

[kimchee]

P1130 AND P1135 at the same time on the V6 Camry. 6 years ago it was intermittent, check engine light comes on for 100 miles then automatically off for another 100 miles. It was on an endless on and off cycle forever, making a rush for smog check when its off. Then this past 18 months light stays on without automatically resets. I have a DENSO on order, it's my 4th one for Bank 1 Sensor 1. I think the last two DENSOS were fakes although the check engine light came off for the first few months. Funny it performs like new, very smooth and no lost in performance independent of on or off light.

I cleaned the catalytic converters and the O2 sensors, and then I got the same issues you are describing here in my 2012 ford F150

[erickharris]

You sound right i have a coil bad and o2 bad after getting new cats but the coil been bad its the 3 way pigtail plug flex fuel connector. i will be replacing that tomorrow

[thomasfoy]

Thank you! I've been having same issues with my 06 Subaru Forester I'm just going to replace both O2 sensors now and then go from there. Great video. 👍

[tsahiv]

Thank you. I got a similar problem on 2011 1.2TSI but throwing p0136 and p0140, also thte engine runs poorly with poor gas milage with no misfires. The car was at the dealership 10 minthes ago, they replaced o2 sensor (bank 1 sensor 2) and igniters. problem kept coming back. i took the car yesterday to the dealership again. the car is still there. i will ask them to replace the ignition coils aswell.

[elnosworld]

Very interesting.

I have a 2015 Toyota Corolla and then I’ve had a lot going on recently
I have 443, 871 miles on the car
I’m the original owner and I’ve taken pretty good care of it up until last year and a half
Money became an issue
So I wasn’t on top of things

But my car started bucking whenever I wanted to give it gas. If I gave it a little extra push, it would start bogging the track off light would come on, and I essentially wouldn’t really be able to drive it more than like 10 mph until I could pull over.
First time that happened I turned the key off and I removed the key from ignition. I put it back in a couple minutes and cranked it over and it went back to normal.

Things were going bad on my car. I was throwing codes for misfire on three and four. Those were replaced recently months ago I had Code replaced the coil and the spark plug on that one.
Well, it turns out since it is an all electrical car that there were many
My brakes for one there were times where I didn’t think I was gonna be able to stop. Yes, I needed new rotors and pads and those were replaced but I still was having this issue where it seemed like I was struggling to stop my car.
Turns out it was my alternator, and I believe it was my PCV valve because that had never been changed
So when we were in there changing it, we realize that all the vacuum hoses were cracked
All of them were replaced, except for one that one actually connects the other end through the vacuum hose or line to the sensor, which I just replaced, which is the purge valve
That is malfunctioning the brand new one just like the old one
It’s giving a rat noise and at first it was kind of slow and now it’s really sped up
My car will buck even when I have my foot on the break
So I went to one of the parts stores and had them run a scan on it after all this had been done, and it comes up with code 4020 which indicates quite a few things for 2015 Toyota Corolla
When we were in there, changing the PCV valve, we should’ve replaced the O-rings on the fuel injectors that never got done, and I had no control over it even though it’s an inexpensive replacement
Because of financial issues
My son was the one who was supposed to get the O-rings because his friend is very Mechanic landline and was doing the majority of the work and walking him through what needed done and he just decided he wasn’t going to get them even they’re only like two dollars

So I feel like that needed to be done and wasn’t but the code that it’s throwing could be something to do with the temperature so this could be a solenoid, possibly or something of that nature in my opinion gas cap they took off and they listed in the gas tank, and there were something unusual, but no one ever bothered to fill me in with that meant

Needless to say, it comes up as the catalytic converter
Now somebody here on YouTube said that if you’re getting a code for P4020 don’t think you can replace the sensors meaning the O2 sensor, upstream and downstream and that that’s going to correct the

He says what the problem is, is actually the catalytic converter and that’s what needs
That’s not cheap
And it’s out of my financial
Then again, so the sensors

But sometime ago, when I had codes ran on this car when it originally threw the check engine light, which is over a year ago it said it was downstream sensor under the hood, which is up against the firewall
Ideally in my humble opinion, both sensors would have to be replaced at the same time, but I’m almost positive it through an sensor and I think that is under the hood also because there’s another one down by the charcoal canister

I just don’t have anybody to help me sort it out, and I am not mechanically inclined as I wish I was

My son seems to think it’s jerking, and it is a misfire even though that’s not how the computer is reading it
Which is why I find this video so interesting

Because all of my coils are essentially brand new, and so are all my spark plugs, so they were not done at the same exact time

Yet I had a mechanic, tell me that when I bought my coil, and even though it was brand new that it might be a fail when you buy anything off-line like that that could be the case, but then parts stores do the same thing and so when you walk into a store and buy some thing from them, there’s no guarantee that that’s gonna be good either
That’s what they were gonna do with my hoses. Make us wait two weeks for the vacuum hoses and order them online just like we did so we bypassed them and ordered the ones that were available the one that I need for the vacuum line which wasn’t replaced and the hose is cracked And connect to the sensor that’s malfunctioning which is brand new cannot be sourced anywhere, but Toyota and even though it’s not a very big hose it’s probably going to have a big price tag

And of course, I’m sure that has a lot to do with it even though the person who worked on my car said it really shouldn’t make a difference at all if it was replaced, I would feel much better, but there is a hose on the other end of the vacuum line which connects to the sensor and I noticed that that little piece that little tiny hose which connects to the sensor and then connects to the vacuum line is very hard and brittle and even though I can’t see a crack in it it’s flared at the end that connects to the sensor, so I’m wondering if there’s some type of a leak there and that that is creating the issue

It’s too much and not having anyone to help me sort it out has been extremely frustrating along with the financial challenges

My son has put me on that’ll help me with nothing else and I’m in my car for 7 1/2 years after being discarded by my ex who was very abusive, but my family left me here and all I keep hearing is I waited too long to do some thing to put myself in a better position, which obviously doesn’t solve anything it’s just insult injury

Any input is always appreciated. Thank you for the video. I think it’s very helpful.
