You guys never fail to bring an educational, simple, instructional video to your viewers. Thank you very much.
+Destiny Kilpatrick Thanks for checking us out. 1aauto.com
Agreed….
I suspect the reason why you replaced the passenger side is because the drive shaft is in the way and a line wrench is not the solution to removing Bank1 Sensor 1. You will need to cut the old O2 sensor so a socket will fit on it. Unless you want to either disconnect the exhaust from the manifold or disconnect the front part of the drive shaft. Bottom line is the upstream driver's O2 is much more difficult to replace and think twice before taking on that one. All told I had an hour of labor. I have a 2005 Yukon Denali XL.
I know it's a pain and I don't know this particular vehicle. But you could try removing the exhaust hangers. That should give you some clearance. If that don't work then just pull the shaft. Maybe an Offset O2 Sensor Socket on a swivel ratchet would work. I was gonna suggest a passthrough but that only works if you don't have a connector on the new O2 sensor. I always suggest soldering if you don't have a connector.
Great video. I have a 1999 Chevy Express 1500. My code reader said I had an issue with bank 2 sensor 1. I didn't know which side it was until I watched your video!
Anhtuan Phan We're glad the video helped you out. Thanks for watching. 1aauto.com 866-403-3393
I am really impressed he broke that loose
+@oscarjones5773 Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I just applied the same technique for the same sensor on the same 5.3L exactly, and I am here to tell you the angle I have going will not permit me to turn it the way he does in this video @2:21 mark. My wrench ends up hard against the torsion bar. For me, there is just no room for that maneuver. I am pulling more toward the passenger door whereas he is pulling more toward the front then I am able to. My fitting must be more around the back of that pipe then the one seen here.
+rebelbrowser One last attempt, and I got it from over the top of the frame, using the wheel well area.
It's a great video, shows me how to save money. Great job
+Lamont Watts Thanks for checking us out. 1aauto.com Thanks for checking us out. 1aauto.com
you did the easy side , how do you get to plug on driver side.
So much time saved with you explaining bank/stream
+Jason Scammon Thanks for the feedback!
2019 video still relevant great job
Thanks for the feedback! +Vincent Jenkins
Is there any difference from the upstream and downstream as far as the plug ins?
I looked up that part on your video and website for my 2005 chevy suburban 1500 series, but it claims it doesn't fit. On your video its printed that it fits my year.🤔
Thanks 1A auto very HELPFUL
+R G Thanks for checking us out!
Do you recommend me buying AC Delco or Bosch for my 2004 Chevy Silverado?
Thank you.
Is it a fairly universal rule of thumb that bank 1 is the bank with cylinder 1, and bank 2 is the opposite side? How often is bank 1 on the passenger side?
It kind of depends on the firing order of the application. You are correct that the bank one sensor will be on the same side as the number 1 cylinder head. The 5.0 Mustangs did have the number 1 cylinder on the passenger side. Ford set the cars up that way to help give them their signature GROWL...lol Thanks for stopping by 1aauto.com 888-844-3393
Thanks for the video guys. I always watch your vids before any projects. Very helpful. I have a question. My scanner tells me efficiency below threshold bank 1. But it doesn't tell me if its sensor one or sensor two. How would I know what sensor is bad?
Thanks for watching. If any of our viewers needs to make this repair we carry the replacement oxygen sensors shown in this video on our website. Here's alink to them. goo.gl/uvaWt7
can you give me an idea when i should change oxygen sensors / i would think only when a check engine light comes on ??
As long as they are working okay, and they are not triggering the check engine light, you should be okay. Typically they get changed when they fail. Thank you for visiting us on TH-cam. 1aauto.com 866-403-3393
Do you know any tips on how to remove the upstream(sensor 1) on the bank 1 side? The transfer case shaft is getting in my way. I really don't have time to remove the transfer case shaft to do a o2 sensor replacement...I also don't have a jack so I'm laying on my back. Thanks
Thank you for watching. Unfortunately we do not have a video for your application. We will keep this repair in mind for future videos.

How to install smag pump on 2001 chevy s10 pick-up
This is for anyone else running into the same problem. I approached from the driver's side. I was able to get my left hand up and threw to the harness connection my right hand through enough to unhook it and reattach it. If your arms and hands are large, you may need to drop the drive shaft. I did this job yesterday and was surprised when I finally found a spot for my left hand to get up to the harness connection. That was the hard part.
You really should. Nobody needs the video for the Bank 2 upstream sensor. Bank 1 is the SOB.
O2 Oxygen Bank 1 Sensor 1 Much harder. I have small hands as I am a woman and trying to wedge them up in that tiny space was difficult. Would love to see a video on that too. Turned out I had to shove my hands up there to reconnect and got really cut up on some of the sharp edges. Also the black clip just wouldn't come out. Finally had to cut it, but getting tools into that spot is very difficult. Definitely suggest safety goggles for Sensor 1 Bank 1. Also found out my truck is Canadian
Hey I have a 2007 Cadillac Escalade esv The check engine light came on in the cold was (P0050, P0154, P0155) Bank 2 sensor 1. I would like to know which sensor I have to get and if it upstream/downstreamI. Also please let me know which side of the truck is the sensor located. It would be nice if I can get a link for the sensor
When I replaced that - and fixed gas line after I damaged the wire harness to the 2 bank sensor. How can I find the route to replacing the harness.
So I wanted to know if you clipped the blue tab that locks the harness connection together in order to get the connector to release? I have a blue tab that I cannot get to release. Thank you
Do you have to reset anything after install?
Would this apply for a 2013 suburban as well or would there be a anything different involved?
you guys m make it look so easy... it's there labor that gets your pockets

If it's at 0.5 hours that's just $40 at a reputable shop. Ask to see the rate chart for the repair next time. I always do, they have one, and if they don't show you don't go there. I use to be a tech at a shop and know how it works. If you don't know it's easy to scam you.
Wonder if you could help me out. I changed the sensors on the upper and the lower Banks and I'm still getting the code po140 and 160. I even changed the mass flow sensor also. Is there something I'm doing wrong? If you can help me out I really appreciate this. Thank you
+Miguel Cruz We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
A friend ordered 4 Walker 02 sensors for my 06 Silverado. 2 of the sensors have the same part number and the other 2 have matching part number. I can only find one number online that identifies one number for the drivers side, before catalytic converter and all other descriptions say they can go before or after catalytic converter. Does it matter where they go as long as the harnesses match? Obviously, I'm not a mechanic, but check engine light lists a couple o2 sensors banks are bad.

I'm not 100 % sure on this truck but if your upsteam O2 sensors have 4 wires. Two are for the heater and the other two are for the sensor. I think some of the older sensors had one or two wires. Those didn't have a heater built in. Not sure if this helps but the answer is yes sometimes it does matter.
Hello!
Is this close or equal to a sonoma GMC 2002? Im trying to change o2 sensors in mine.
Thank you in advance!
+Ruben Chipuli This procedure might be different for your application. We do not currently have a how-to video for this particular year, make and model. Thank you for asking! 1AAuto.com
Hi, I have a 1999 Suburban i know its a little different. I am having trouble unconnecting the plug. Is there any tips or suggestions?
+James b Thank you for watching. Based on the location of the part, you may need to use a thin flat headed tool to press the tab and use another hand if possible to remove. A lot of the time dirt or other debris gets into the position and causes a tough time removing it. 1aauto.com
Too bad you only showed the easy side. How are you supposed to reach the tab to cut on the driver's side upstream?
Everyone does videos showing the easy jobs. I have yet to find a video that shows how to replace the bank 1 upstream O2 sensor.
Thank you
Is this the same process for 2003 Cadillac EXT
+yogi tha LS budget Builder The installation process would be very similar.
My Bank one sensor is bad. Should I just replace all four of them. 05 Suburban Z on 8th digit. 92K miles on it.??? Thanks
+William Steinhour You can if you want to. If you just replace the bad one you should be okay as well. Here is a link to the O2 sensors that we carry on our website for your truck.

1A Auto Parts i have engine light and got it checked and was told it was a o2 sensor on top of engine but never replaced it. I now want to replace it as well as others since its original 99 Silverado parts on it.What do you think i should do?
How would i knoe what sensor to change??
anyone have issues with the engine idling terribly low after replacement? even after unplugging the battery for 15+ minutes?
Will a torch help the sensor threads loosen up?
I'd stick to penetrating oil before going to a torch. Hope this helps you out. 1aauto.com?TH-cam&CTA%20Comment&ATony 866-403-3393
Thanks, the correct wrench size is a 22mm BTW.
@sparta a 22 mm is the same as a 7/8 btw
What about resetting the code after the sensor's been replaced
Mine says 02 heater circuit (bank 1sensor1)..could it be the driver side upstream one
Yeah, start looking for a short in the harness unless you know for sure it's the sensor. I've seen the connectors get dirty too. Normally the O2 sensor dies from carbon buildup and not a heater issue.
What size wrench is it?
It says 7/8 but you can also use 22mm same size
What do you do about the codes within the trucks computer?
+Ziggity Zee Thank you for watching. Upon replacement of the part you may reset the codes, but on the other hand if this part is the issue after 50 to 100 miles or 25 or 30 startups the code will clear itself out and the engine computer will identify all as well. 1aauto.com
I hooked a code reader up today and, well its a scary thing... thanks for the help tho have a gooder
RIP headphone users.
is this the same as a 2000 Chevy tahoe
+Luckyy Rodriguez The part shown in the video does fit your application. It should be the same or a similar procedure. Here is a link to them on our website. Hope this helps you out. www.1aauto.com/o2-oxygen-sensor/i/1aeos01019?TH-cam&CTA+Comment&Xu463XT8lk

I have a2008 suburban I wonder which side is the bank one sensor 2
@@gabinohernandez6732 should be driver side after cat
You need to buy your mechanic a real pair of cutting pliers!
Show me side of driver how to unhook it.
so no one ever gives the answers that everyone wants! 04 avalanche, are the upstream and downstream the same? when u buy online it looks exactly the same, when u add it to your cart it’s the same part# but when u go back and look its 2 different part #’s for upstream vs downstream?
+Jason Y They are listed as being the same on a 2004 5.3 1500 Chevy Avalanche. Here is a link to them on our website. Hope this helps you out goo.gl/jDgTx2
Lololol those o2s neverrrrrrr come out that easily
I can't get mine off ugh!!!!!
