99-06 5.3l, if you hook up and cannot read check engine light, chances are your cigarette lighter fuse is blown, sounds weird but true and saved me. Hopefully this helps someone out like it did me🤙🏼
Appreciate the video. Your instructions made replacement so easy. I spent 15-20 mins on it and it was my first time. Shout out and a big thanks from San Francisco Cali
A true gentleman and precise in your descriptions and explanations. You're the only one 5hat has given a clear picture of has no need of hocas pocas out of this world bs. Thank You
Thank you! Thank you! I've watched a few of these tutorial videos and you are the first one who explained what bank 1 and 2 and how to locate them! Thank you!
Hey Bowtieguy; Austin. Great vid. Same thing happened to me. Replaced the bank 2 sensor 2 on my 2000 GMC 1500 and it wouldn’t run. Disconnected and reconnected battery again and Shazaam! It’s running! Thanks for the heads up.👍🏻
I was talking to Military and that's exactly what they always taught me to do disconnect the negative terminal on the battery I don't know why but that's the way it is that's the reason why a lot of people do that in cases of wire get rubbed up somewhere always disconnect the negative terminal
Got this issue myself to do. As usual glad yo see you have a video of how easy it is to change. I was at the dealer figuring my airbag issue out ( clock spring) and they found that sensor issue, quoted me $158.99 + tax with 0.8hr labor LOL.
@@qalv97 I got a 1,265$ tab to change all 4 on my Chevy dealership. I’m taking the old school fashion way of doing it myself for much cheaper and quicker.
Hey, brother. Thx for the videos. This one in particular was very helpful. As far as disconnecting the battery, I was told that it helps to reset the ECM. Anyway, that's my 2 cents. Keep 'em coming... Mark
I'm a woman 65yrs old what steps do I take to replace the sensor. Tools included . I've got a Blessed Big trip over 700 miles to and from . THANKS 🙏🙏🙏👍🙏🙏 AMEN AMEN AMEN ❤️.
I don't know if this has been working or not my third try I'll quit in case it has been I like the other guy said straightforward to the point looks like a simple 15 minute up and down job thanks for the help very good
It's cool that you indicated bank 1 bank 2 but all sensors are the same for chevrolet silverado. Both are upstream and downstream and doesn't matter for these specific models
Well I’m the lucky winner, after I changed the O2 sensor on bank 1 sensor 1 and disconnected the battery as well it had issues idling. So I just disconnected the negative for 10 minutes and reconnected it and problem solved 🤭. Good ole tech aye
Step 1: What I would do is get a scan tool and pull diagnostic trouble codes to see what the onboard computer in your vehicle is saying, or in this case where the PCM - is indicating the fault. Step 2: Once figure out the location, for example, if it's Sensor 2 Bank 2, which this O2 sensor is downstream past the catalytic converter on the driver side, check the wiring harness for any burns or exposed wiring insulation. Step 3: Take the known location of the faulty sensor, and switch it with the opposite side of the rear. Pull codes for a second time, if Sensor 1 Bank 1 appears and Sensor 2 Bank 2 disappears on your scan tool, then you know it's the sensor, and not an issue with wiring of the PCM computer module. These steps should provide a more accurate diagnosis, rather than throwing away money on unnecessary parts. Unplugging the battery does not always work.
Hey, THANKS for the video. Question; did you replace ALL FOUR of the sensors ? Or just the one that was defective (if you could tell which one) ? How reliable is the "problem diagnosis tool" to identify WHICH of the sensors are bad ?
Like anything else on vehicles replace in pairs. If it's actually the o2 sensor that's bad. On these silverados there's 4 sensors 2 up stream 2 down stream. What ever the code is for up or down replace both. This isn't a GM repair must it's just common practice. If one in the set is bad chances are the other isn't far behind. Also when it comes to the up stream o2 sensors they send fuel and air data to the ecm, so when you only swap one the other most likley is going to report slower and possibly cause another code or the same code just for the old sensor.
So to be clear Bank 1 is on the side of cylinder #1 which on these GM is the driver's side, but not on every vehicle or those with a transverse-mounted engine. I sure wish my bank 1, #2 was that easy to get to on my '05 Yukon XL as the plug is in a goofy spot behind fuel lines & other garbage. They do make a socket that allows you to remove the sensor w/out cutting the line. They are $5 on Amazon & can be a big help especially if you are pulling it for some other reason like inspecting or testing it. They should be installed with anti-seize on the threads and if not or just damn old & corroded you may benefit from putting some heat on it as they can often be very stubborn. Given how much of a PITA everything is to get off on my 05 I doubt a short wrench will be the only tool I get to use today.
I totally get were you are coming from about disconnecting the battery to change a tire, etc......however, the reason fort his is to eliminate the power supply in case it for some freak reason would start up buy itself. The correct way is to disconnect battery, try to start the car, put key in pocket. If car starts after disconnecting the battery, contact supervisor immediately! lol (paul) ps....I really appreciate the info about the banks and what side they are on.
Do your self and others that work on that truck after you a favour and put a little anti seize, never seize or copper slip on the threads. It will be a much bigger job about five years or so down the line when you replace that sensor again, and you strip those threads because they have galled.
Thank you for this. Service engine light just came on and I assume it's the 02 because they haven't been changed for as long as I know. (Getting the code checked tomorrow)
I appreciate the help man save me some money also cuz I was just about ready to let the shop do it also straightforward like the other guy said no BS looks like a 15 minute job time you get it jacked up and let the Jack down
Haha easier said than done, my 2004 GMC Savana was one of the hardest ones I've done, had no choice other than to torch it to get it out, luckily the threads were still intact it was not easy.
Your video headline says this repair is for 99-07 Silverado but you say it is 02 through 07 and a half Silverado. Mine is a 2001 Silverado. Should I watch your video?
My mechanic said to disconnect the battery, replace the sensor, then take the battery cables and hold the terminal connections together for 20-30 seconds. He said this resets the computer so it goes back to pre failure settings so you will not burn out the new sensor right out of the gate.
This also sounds like a nice way to reset your computer if your on the side of the road without a scanner and need a reset also. Thanks for the comment.
If you have ever had a wrench fall and jet japped between sat the starter bolt and groung while you are nearby captive under the truck, you will disnonnect the negative battery terminal from then on
Hi Bowtieguy, I watch a lot of your videos buddy; had a quick question for ya. If you were to buy a replacement engine for your truck what route do you recommend going? Would you say to get one of the GMPP crate engines or do you recommend rebuilding my block with upgraded internals? Thanks bud
What aftermarket dash cluster do you have in there? Mine just shorted out and everything resets when I start the truck back up, changes language settings, trip set, and the speedometer bounces around when maintaining a steady speed lol See video 5:07/6:38
Robert Watkins no just the up stream O2 on drivers side only, I would test the others while your in there by back probing the two black wires and Checking amount of resistance
I replaced the battery on my truck and it wouldn’t start either. I did some research and found out that my truck no longer recognized my key. I had to turn the key to the on position and leave it there while the security light flashed. When it stopped flashing I turned the key to the off position. I had to do that process 5 times but it finally started:
I was truly astounded by how easily your sensors came out. I just got my truck a few weeks ago and bam! It codes on me for bank 2 sensors 1 and 2. I think the guy at the factory pulled some kinda joke and used some loctite instead of anti seize because they are stuck in there like crazy! I'm reefin on the wrench so hard I'm moving my truck but the sensors simply will not budge. Any tips for me?
Thanks for confirming location. I have code P0060 which I assume is Bank 2, sensor 2. Is that correct? I also had P0053 and one other show up as well. I reset the OBD and for now only P0060 showed up. Is it safe to say that the others showed up because of P0060 and if I wait long enough they will reappear? In other words just start with replacing B2,S2 first and then wait for result. Its a 2005 GMC Yukon XL Denali. Thx, Michael
Do you need to replace all of them or just the one that shows up in the code or both sides? And what if is not showing in code at all. I had to change the throttle body and now the light is back on and huge decrease in fuel economy.
I got a 03 Silverado z71 5.3 rough idle lacking power black smoke flashing check engine light. I've changed plugs,wires coils and fuel pressure regulator and got new AC Delco sensors and ejectors ordered and will be here in a day or so. I question is did your truck have these same symptoms before you changed your O2?
My cats were clogged so i got some basing new ones an am ready to put them back on from a straight pipe. I also have to change both down stream o2 sensors. I hope after I put my catylic converters back on and put the mew o2 sensors on that the check engine light will go off. Any help please?
It's usually 7/8. The O2 sensors measure the amount of oxygen (hence the name *O2* sensor) so the computer can apply the proper air/fuel ratio to the engine.
@@JuanRodriguez-pd9nt that is what it was. Good thing I decided to check that first cause I already had it lifted ready to check the sensors again. Thank you!!
I replaced my bank 2 censor 2 as it said low voltage! Now my reader reads b1 c1 b2 c2 no voltage detected and it also threw about 4 more codes it wasn't reading before lol. About to put my other one back in at least I only had 1 code then not 6. Even got a random misfire code which is the worst, and a throttle tac code. Unreal

How do you know which senior needs to be replaced or do you just change all 4

What size rench
Is this metric or a 7/8? 7/8 felt loose on mine
You find out what it is?
Soy catalytic converter isn't bad it's just an o2 sensor?
It does make it safe
Are all 4 sensors the same. I want to change them all.
So then it's just 2 types? I have to do this and trying to figure out what to order. Itd be a big help thanks!

Can i just delete the cats and go with a true dual set up?
Elerre Lopez you'll have to get the truck tuned so you won't have a check engine light for no cats.
Yeah you can
To get into the truck first disconnect the battery
Yes suhh. Big help
Always disconnect your battery first then use jack stands in case you're hydraulic Jack fails and you get squashed 😭
Do u have cats on ur truck when u had this done?
we're or wat store u bought the 02 sensor?
They tell you to disconnect the battery because things reset afterwards. Just what I was told.
Where did you get the mirrors
What type & size was your open end wrench ? The 02 pulls fuel up ?
It's usually 7/8. The O2 sensors measure the amount of oxygen (hence the name *O2* sensor) so the computer can apply the proper air/fuel ratio to the engine.
How do you know which bank?
Yesterday I replaced the because my light was on. My light went off and the truck started just fine. Now this afternoon it won't start. Any ideas?
