Thanks for you video I just failed inspection on our 2010 Nissan Altima because of Code P0420, they told me it could be a 02 sensor didn’t say if it was the front or rear one not really sure what to do.. But I think I’ll just try to replace them both tomorrow morning. Wish me luck! Thanks again for your video brother..
You're very welcome. How did everything go? Did you pass emissions? 😊
@@TrickShiftGarage Yes sir we passed!
How many O2 sensors does a 2012 nissan Altima have 2.5 liter with California emissions since I'm in California. Love your channel, you've helped me change out my own struts and my axles, thanks so much for your awesome videos
Hi John, thanks for watching we really appreciate it. There is one more O2 sensor that is further downstream from this one for the California compliant Altimas. It is located after the big resonator and before the "Y" pipe that splits into each muffler. I'm not sure exactly how to replace it but I'd assume it's very similar to this procedure. Thanks again for watching 🙂👍
If my O2 monitor is not setting after a battery replacement for smog check in California, which one you think I should change? The two downstream or the upstream, O2 heater is set just not the O2 sensor one is not set. Also, there are zero codes for the vehicle, everything is ready, catalyst, EVAP, O2 heater, only one is O2 sensor.
Good explanation of the replacement, I will use it to change my sensor
Glad to hear it Drew! Thanks for watching!👍
I see you’re very fond of the 2012 model ! Your videos have been very informative for me thank you.
Side question . My mass air flow sensor continues to pop as a problem, however I’ve replaced it a couple times and it can’t be the problem. My rpm’s tend to fluctuate like crazy. When I let go of the accelerator the rpm drops to 800 really fast. Currently now it started to jerk when trying to accelerate past 2k Rpm’s. Have you experienced this ? Thanks again
You're welcome, I'm glad to hear how they have helped you 😊
To answer your question, try checking out the mass air flow's (MAF) wiring to see if it's cracked and showing bare metal. Also, check the seal around the MAF that it's screwed into, you don't want any air sneaking by it. You can also check the entire intake system for any possible secret openings and close them up, check over your clamps on the intake elbow, make sure they're tight. I discovered my intake elbow was rotted out in between the "ridges" where it bends, it could be letting in more unmetered air into the engine which could be the cause.
About 6 months ago the electronic throttle body was sticking and not letting the throttle plate open correctly, so it would be sluggish on acceleration and then it would open up once it started working again. So maybe that is something to consider in your situation as well. Hope this helps! Thanks for watching! 👍
FYSA you can use a battery termincal cleaner brush to get into the threads to clean them.
Great tip! Thanks for watching! 🤟
Great video! Thanks for the tutorial
Thanks for watching! 🙏
where did you buy yours from i have a 09 nissna Altima too but I Didnt know which one to buy i need to get my upstream and downstream
Have a 2011 rogue SV with manifold cat, no one shows how to get the downstream sensor out. Looks like going from underneath is the way to go but there must be a trick on how to do it
I have a 2014 Maxima S 3.5L and it’s giving me this code P2097
Post Catalyst Fuel Trim SYS B1. Is this the same one?
I had the code p0171 and changed the upstream 02 (under the hood). Cleared the codes and drove around. A few days later code p2096 pops up. Would this be the downstream needing to be replaced? I got a new cat and manifold last year so I’m not thinking that’s the problem
I wish the part was included in the description
Not sure what you mean. Push the tab IN and down? Pull the tab OUT and down? Pushing down doesn't do anything. It's a tab, so it has to move inward toward the wire harness or out and away. That's kind of a critical component of this who thing because you either push down and break it or pull the tab out when it needs to go in or vice versa.
Yeah, I think it was push the tab in towards the wire and then pull the plug out. Thanks for watching! 👍
I have a 2008 2.5s. I got the error code for Bank 1, Sensor 1. Is it in a similar place to the one you're replacing here?
The bank 1 sensor 1 is the O2 sensor close to the exhaust manifold before the catalytic converter. The one in this video is for bank 1 sensor 2 which is after the catalytic converter.
Here's the video for bank 1 sensor 1:
ua-cam.com/video/UE1r9-fpe7s/v-deo.htmlsi=tGhxkX7aW_fGlpeQ
Hope this helps, good luck and thanks for watching! 👍
Where would the Bank 1 sensor 1 be on a 2008 Altima 2.5 SL code P2A00?
Whats the difference between the upstream and downstream sensor (not talking about a 3rd sensor that CA might require). Arentvthey both the same air fuel ratio sensors?
From what I can tell they are. But double checked online and apparently are different. Not sure what the difference is but they use different part numbers between upstream and downstream sensors.
Hey man my old downstream o2 sensor is male and my harness is a female??? i wonder if the old owner rewired the harness? is it possible to rewire or change the harness completely im stuck.
Oh wow, that's unfortunate. I'm sure it's possible to rewire it but as to the specifics I couldn't help you much there. I'd call some shops near you and ask if they'd be willing to rewire it for you. Hope this helps, thanks for watching! 👍
which 02 censor is this one considered to be because i changed the one right in front of the engine and it’s still giving the same code
This one is behind the engine and underneath the car, there's two O2 sensors for this car. I would try replacing this one and hopefully that fixes your code. Thanks for watching Jaydon! 👍
@@TrickShiftGarage the one behind the is considered sensor 1 bank 1 ?
You I’m connected the battery the negative or the positive or just unconnected the whole battery
You can just disconnect the negative side of the battery 🙂
I'm curious, what does a new 02 sensor improve?
Hey MC! A new O2 sensor doesn't improve anything over an old working O2 sensor.
However, if the O2 sensor is bad and your check engine soon lights on, it could drag your gas mileage down, so replacing it will just bring it back to where it used to be. Thanks for watching! 🙂
@@TrickShiftGarage Thanks for the info!
You're welcome! 👍
I don't have a Catalytic converter since it was stolen, straight pipe now. I got this code, obviously will be replacing, will it help with the gas mileage? Also is it the downstream only or should I change the upstream as well? Thank you. Love your vids. Easy to understand and follow.
It will help with your gas mileage because the car's computer can properly read and adjust the amount of fuel according to the oxygen level in the exhaust. Thanks for watching! 👍
Love the video's, question I am getting a code on mine code p0146 (o2 sensor no activity detected bank 1 sensor 3) can't find it anywhere, is the one in your video it?
Hi, thanks PV! Code P0146 usually means the O2 sensor after the catalytic converter so this should be the one. Do you have the 3.5 liter V6 engine?
No its a 2.5 I searched for code and couldn't find any 3 sensors
Ok was just making sure because the 2.5 just has just 2 sensors. I'd replace this one and it should clear it up. 👍
@@TrickShiftGarage thank you buddy. Thanks for all the great videos
The 2.5 has a 3rd o2 past the resonator pointing up
Where is the bank 2 sensor 2 on 2015 Nissan Altima 3.5? Ty
Can I gut both cats and space the rear o2 sensor?
You certainly can gut them out...but honestly, I wouldn't recommend it.
It would cause the engine trouble codes to light up and the engine will probably not run right. The O2 sensors will send conflicting signals to your ECM (the cars computer) and your fuel injectors will change it's fuel delivery, possibly putting it into a kind of "limp" mode, your gas mileage will probably go down too. Spacing the O2 sensor will send more inaccurate signals as well. Hope this sheds some light for you, thanks for watching! 👍
@@TrickShiftGarage I have an intermittent p0420 code, changed the exhaust manifold cat and first 02 sensor last year. My 2012 Altima 2.5 doesn’t have power past 3200rpm and I can’t go faster than 85mph. Hillclimbs suck. What if I just gut the rear cat and spaced that last o2 sensor with 2 non-Fowlers? I just need a temporary fix for my sluggish acceleration. And that’s the only code I have.
@@TrickShiftGarage fixed the issue, had a torn intake hose 🤣
Haha! That's awesome. I found my intake elbow was torn while taking off my throttle body to clean it. It didn't cause any trouble codes at that point luckily. Glad you fixed it though 👍
so why did you disconnect the negative terminal ?
When the negative battery terminal is disconnected, it eliminates the risk of accidentally causing any electrical damage to the sensor or other components during replacement. Thanks for watching! 👍
@@TrickShiftGarage ohh okay, I appreciate the response, your video was helpful as i’ve changed my downstream sensor today ! super easy
Is that Bank 1 sensor 2? I got code P0138
Yes, P0138 code is a max voltage fault for this O2 sensor. Replacing it should set you straight. Thanks for watching! 👍
Link for o2 sensor ??
Is possible to change down stream sensor without getting under the car
No, it's not possible for this O2 sensor unfortunately, the only way to get to it is going under lol. Thanks for watching! 👍
What brand of ramps are those
The ramps are the Pittsburgh brand from Harbor Freight. Here's the link:

Was getting a p0138 replaced it now I'm getting p0138 and p0037.. 🤷♂️
Hi Angelo! I'd return the new O2 sensor and tell them they gave you a bad one. I remember years ago I had a similar issue. The code didn't go away, went back and they suggested another brand (I think Duralast) and the code went away.
Can a bad o2 sensor also cause transmission DTC's?
Hmmm, I don't think so, at least I've never seen/heard of it before lol.
But I suppose it's possible, like if the engine is running very poorly, rough idle, misfiring, etc. The transmission control module can misinterpret when and where it's supposed to be "shifting" (our CVTs are continually shifting lol), which in turn could possibly lead to poor acceleration as well as causing other erratic behavior in the transmission, which in turn could cause a transmission DTC. Either way, if you have a bad O2 sensor it would be a good idea to replace it for the engines sake, and who knows, it might clear up your transmission issues since the engine will be running healthier too. Hope this helps and let us know how it goes, thanks for watching! 👍
@@TrickShiftGarage Thank you! I'll get it replaced and see what happens.
