Thank you for showing how to install and where these are. So many stupid videos with annoying music and nonsense in them. Straight to the point, thanks again.
Very helpful and I'm glad you started with bank one sensor one bank one B1 very helpful all the other videos that they was going to skip to showing how to remove bank one B1 and that's the one I needed to know about on my 2000 Cadillac Escalade thank you God bless very helpful
There are thousands of these Vortec V8 engines still in service, so thank you for this detailed video. These O2 sensors inevitably go bad after 200K miles (or sooner).
What a Great Job! Excellent in every way. We have to get this done next. Now he might try doing it him self since our 1999 sierra is a lot like your truck.. Thanks for this post.
I got a 93 with a 454 in it how many Austin sensor supposed to be on these things I got one foot back in but I was wondering if they are two of them it has a 5-speed
Slightly surging engine and the check engine light saying that the Oxygen Sensors were suspected bad 😂 BUT, it turns out that the intake Manifold Gaskets cause an O2 sensor check engine light. I made a video on it and thats what fixed my issue! It's very common with these engines. I wanted to replace the O2 sensors anyways as part of my tune up on the truck since the truck has over 260,000 miles on it 😁
Lots of information except for what i was looking for. I still have no idea the location of these sensors especially the Bank 2 sensor 1 I’m trying to find to replace. The video shows a close up of you replacing them but is not exactly sure what/where that is.
My 2003 GMC Sierra 1500 has a Vortec V6 which evidently do not use the GM AFS 138 sensors as shown in this video. I removed all four sensors from my truck and discovered that all four were identical as they came from the factory. Since the GM AFS 106 (also shown) do appear to be correct, I'm assuming that I should use four of these as replacements. Am I correct?
Awesome video. Thinking about changing mine on 04 Tahoe 208000 mi. during tuneup. Just searching for recommendations. Should I replace them or wait until I have an issue with one of them? Thanks for the great detail on DIY.
Some people consider them to be a tune up item, like spark plugs and wires. So you can do it if you want! Can't go wrong swapping it out, BUT the majority just wait for the check engine light to go on to swap them out!
@@ufixitauto5237 how do I know for sure if mine are bad? It had a check engine light, then I cleared the code. I’m pretty sure before I cleared it it said I had a bad o2 sensor
Hey loved your video so I'm going to try to replace one of my O2 sensors. How do I look up online which sensor to buy? I have a 2005 GMC Yukon Denali. ? Worried that I'm going to get the incorrect one.
Do you have a check engine light telling you to replace it? If you do, it'll tell you which bank and which sensor needs replaced. To make it easy, you can go to a website of a local parts place like Auto Zone or O Reilly, put in your car info and then look up oxygen sensors. Amazon tells you which parts are compatible with your car if you have your car info stored there. They usually tell you if they are Upstream or Downstream sensors. Just grab the one you need :) in the video, I describe how to differentiate between the two :)
Sorry dude but how the hell did you get your hand up in there to get the clip off for the driver side Upstream sensor without dropping the drive shaft.
I mean, you can! Just make sure it's tight on there so you don't strip it! Some people like to know the exact wrench sizes but I love me a good crescent wrench!
Just bought an 2005 Suburban, yesterday. Engine light came on today for the oxygen sensors. How long can I drive before replacing them? A month? Thanks!!!!
Everything is subjective to the car. Typically, in my experience, bad O2 Sensors cause bad fuel economy and sometimes surging engines but it has not left me stranded and I left it running a while with bad O2 Sensors. BUT, I should also mention that even though the check engine light showed O2 sensor codes, the issue was the intake Manifold Gasket. It's a very common issue with these LS engines. So, if you replace your O2 Sensors and it doesn't fix the issue, then I would look at that :)
Outstanding video! I put a long breaker bar on them and still can't break them loose. Did you have to use a torch on any of them to heat them up before they broke loose? I would assume not, since you didn't mention it. I don't even live in the rust belt! They are original though on my 2000 GMC Sierra 2500 with 125k miles.
My GMC has only 82,000 and the check lights keep coming on and off. Had 2 test check on truck and it comes out with bank 1 & bank 2 senor readings. Do they go out that quickly on a GMC? And, you bought each sensor for $40? Over here in California, auto zone want $175 and $77 + taxes bank 1 & 2 , upper & lower. Bosch not GM parts. Thanks for your video teaching.
Yes I purchased them 40 dollars each! Auto Zone inflates those like crazy. Check my affiliate links in the description. And no, I wouldn't say that it is normal haha. At least not in my experience anyways. That's often the sign of either bad O2 sensors or intake Manifold Gasket. No way for me to know haha
Hmm, do you know if that's the fault of the sensor or the connecting wiring? It could be a bad sensor connector, so you can try to plug in the old sensor to see if it connects just fine. Best case scenario is you just need to change out the sensor, worst case scenario is you'll have to cut and splice the wiring harness off a junkyard donor.
@@ufixitauto5237 found out that the Bosch sensor that I tried installing was the incorrect sensor. Returned it and drove 15 miles to another location for the OEM o2 sensor. In theory it was the same sensor but out of the box the electrical connector at the end of the sensor was not the right fit. It did not click in. So yea you were right haha, Ihad a small scare there.
Remove the battery for a couple minutes and it should reset it. If the issue is gone, then the check engine light should be gone. If the issue is still there, then it'll turn back on. If your check engine light is still on after disconnecting the battery and you still get O2 codes after replacing all of the O2 sensors, then check out my video on replacing the Intake Manifold Gasket because that may be what you need to do. It's a common issue with these vehicles. That's all assuming you have the same type of vehicle as me! 😂
Normally I would, but it wouldn't have made a difference in my application! The check engine light was on, but the engine was actually not running rough enough to make a noticeable difference. It would have been a clip of the same engine idle basically 😂
What codes do you get? If you still get o2 sensor codes and rough idle after replacing the o2 sensors, I would look towards the Intake Manifold Gasket. Its a common issue with these engines haha. It's a little more involved and I did make a video on it!
On my '05 Yukon XL the connector for Bank 1, sensor 2 is the hardest part of this job as you need some baby hands & forearms to get at & seperate it. For those that with those handly little O2 sensor sockets (well worth the $5 on Amazon) in my experience more often then not the sensor will not budge & even a good penetrating oil will not help so take a propane torch & heat that suckered up being cautious of any fuel lines or wiring harness.
I have an 01 GMC Sierra 4.8 liter rear o2 sensors are right but the front ones are not 138 just make sure you guys check your plugs I did a dummy mistake and copied his part numbers and they were wrong for the front o2 sensors so don’t make my mistake lol
From my understanding these are not the right sensor for Canada built trucks.( 213819) is the genuine gm part# for the Canada made trucks and all four are the same.

You don’t like the idiotic music that’s so loud you can’t hear the person talking?😂
"....and then by pulling and yelling I was finally able to get it loose" Ain't that the truth! Thanks man.

As a military diesel mechanic I can confirm that yelling always works, and cursing. Lots of cursing, never fails lol
😄 Lol, 63 Charlie myself

By far the best GM O2 sensor video online...

There are thousands of these Vortec V8 engines still in service, so thank you for this detailed video. These O2 sensors inevitably go bad after 200K miles (or sooner).
Mine went out at about 140,000 miles. It is also a 99 though. Mines the 5.7l v8 closer to a 98 than a 2000+
This is an incredibly helpful and well done video, thank you! I was able to replace these on my '02 Tahoe no problem with this tutorial
What a Great Job! Excellent in every way. We have to get this done next. Now he might try doing it him self since our 1999 sierra is a lot like your truck.. Thanks for this post.
Of course! Good luck!
Thank you for explaining which side is bank 1 and 2 couldn’t find a video👍
If you remove the front passenger wheel, you can access the up stream O2 sensor.
Excellent video and very thorough - thank you for making it!!!
Great job explaining, Thanks for your help...............................
Thanks this helped me out a ton
Thank you ! This is sooooo helpful.:)

What were the symptoms was it hesitating or stalling or no acceleration no throttle response?

How do you no which one is the oxygen sensor and which one is the heating sensor and so forth

I explain in the video in reference to the catalytic converter. Around the 2:49 mark.
My code reader shows P0405 EGR sensor bank 'a'. I assume bank 'a' is the same as bank 1
EGR sensor is different than o2

I guess carefully 😂 it was a tight fit haha
Changed out with factory part engine light back on 😢
It could also be the intake Manifold gaskets. They cause 02 sensor codes too and it fixed my issue after this.
After replacing sensors will the check engine go off on its own or does the battery need to be disconnect to reset check engine light?
Drive it around enough and it should go off if that was an issue. Or just disconnect the battery for a minute and see if that did away with the code.
Does that make it waste gas ?
Is a crescent wrench not advised?
I mean, you can! Just make sure it's tight on there so you don't strip it! Some people like to know the exact wrench sizes but I love me a good crescent wrench!

Are the sensors numbered? Or can they go on any?
No, just two Upstream and two Downstream. Make sure that the Upstream ones are Upstream and the Downstream ones are Downstream 😁
Also my question, are the two upstreams both slot ones? (First time doing this myself)
That one near the wall is really hard to get to

Would have been nice if you showed how it ran before, and after.
