How to Replace and O2 sensor. First jack the car up, then find the sensors and replace them. Thanks for watching don't forget to subscribe.
It ain’t that simple for everyone
Yeah especially in Michigan those things are almost one with my exhaust on my 2001 Silverado took map gas torch and alot of pb blaster better off using a box end wrench and rubber hammer than an O2 sensor socket on rusty ones.
@@robpaul7900 I'm here for an 03 silverado... I don't want to read this😂
Yet you're here too haha
@@zanebauer2974yeah mine were pretty bad but using a torch makes them like nothing anymore I don't mess around I go right for the torch.
You have no idea how fortunate you are to have rust free parts to work on.
Would have been nice to show how to use those funky proprietary sensor sockets...
Would be nice to see how he disconnected drivers side plug or even got his hand in there
Hey bro use a Long screw driver and try to pry the blue Lip it ill came easy after you loose that
You should call this video a tutorial has he did not show the general people anything about removing it. Or installing it you showed a picture Before & After that was it. 7 eights is a standard oxygen sensor size on all-American vehicles.
I wanted to see you struggle with the rusted sensor. I wanted to see how you did it I can’t get mine to budge
Spray it down with bolt loosened solution and let it sit before you break it.
I have a 1999 Chevy Tahoe LT 5.7L 4D, 2WD, and have changed all four O2 sensors. However, the engine service light will come on after driving it for a day or two; Wiring appears to be fine and no exhaust leaks.I did check the heater circuit fuse which is okay. Have scanned it and keep getting OBD II codes P0134 and P0154. How do I find out if it may be a faulty ECM/ PCM?
Ever figure it out?
How did you get to the driver's side upstream wire connector to unhook it? Did you have to drop the transfer case driveshaft? It's a little crowded right there, just curious as to how you got your hand up there to disconnect it. The video wasn't very detailed on the actual process of removing or installing
I had the same problem but finally figured it out with a tip I ran across on another video. I used a small electronics flat blade to pry up on the black chassis mounting clip onto which the O2 wiring harness slides and 'snaps' on. Once you have that clip pried up the harness can be slid off from the mounting clip and then dropped down to where you can actually have a fighting chance to disconnect it. Getting the small flat blade up in there with enough room and light to see what I was doing was very tricky. You may have to tinker around a bit to figure out how to get your hand up there with the screwdriver to pry up that black clip. I did not have to remove the shaft or anything else to remove the Bank 1 Sensor 1 O2 sensor. However I will say this is not an easy task. It is only easy task if you have exactly the right tools, techniques and past experience otherwise it is a royal PITA . I thought about posting a video but that would have required a third hand. Hope this explanation is enough to help someone. Good luck.
100% agree. I have a 2002 4x4 suburban and I cannot get my hands up there between the transfer case shaft and the sensor. Cannot also seem to pry the clip out... chevy made this task 200% more difficult than necessary.
Spent too much budget closing music didn't have time to actually fix the problem just said that he did.
What caused you to change them? Curious. Might help my issue
You should diagnos the Electrical contacts to determine if the sensor is bad before throwing parts at the vehicle. There could be other issues.
Ohm test?
this video help me alot
I had a 2000 model white one bought new great truck
I was just wondering how you determine which one was bad the upstream or downstream
You’ll need an OBDII scanner to monitor the real time voltages coming off each sensor
check the codes bro. it's either bank 1 sensor 1 that's the one before the cat drivers side, bank 1 sensor 2 after the cat drivers side, bank 2 sensor 1 before the cat passenger side, bank 2 sensor 2 after the cat passenger side.
Mine got the p0137 o2 sensor circuit low voltage (bank 1 sensor 2) error code. How to tell the exact location of the sensor?
Driver side after cat
would have been nice to be able to hear and see the whole prosses. needs volume
What size socket did you use
7/8" (22mm)
Hey maybe u guys can help i got a 2001 chevy 1500 with about 190k miles im starting to have problems starting it here and there. What i notice is my RPMs drop while turning the key. Occasionally this happens at random sometimes it turns over fast and fires up sometimes the rpms dip when it turns on trying to go to 0 and goes back up. But this last case i couldnt get it to start without holding the key extra long. When i got it diagnosed abt a mounth ago for the engine light it came up as an O2 sensor. Is this sensor connected to my rpms dropping problem? Also another note is i have been going between mid grade and regular. Thank you in advance!
I own this Van also. My veh. Starts and runs good but my fuel economy is not what it should be. My engine light came on and it indicates it's a bad Oxygen Sensor.
However, it could be a problem with the Catalytic Converter, the MAP Sensor that needs cleaning diagnosis or replacement, a Vacuum leak, do a smoke test. It could also be plugged or dirty injectors. All these things will affect your fuel trims. You need someone with a very good Scanner to diagnose all the above.
Good Luck....
Thanks so much
That plug on the driver side is not easy to get to.
Don't you need to replace all four what's the sensitis doing too
You can also unplug it and slide a socket on it if you can’t afford the special sockets.
Use a open end wrench too
Open end 22 mm wrench. No need to buy a stupid$30 socket
You have to cut the wire at sensor for a socket to take off...can't put it back on that way buttercup
good afternoon my name is Sam I have a 1999 5.7 Chevy Tahoe LT 4 door I'm wondering does the two oxygen sensors on there are they the same if so can you let me know please cuz I gave the truck to my ex-wife and it's failing the emissions test and she already did the gas cap so on and so forth and I'm thinking that the oxygen sensor but I'm not sure if both of them are the same thank you God bless
Both upstream (left and right bank) are the same, and both downstream (Left and right bank) are the same...upstream is between engine and Cat, and downstream is between Cat and tail pipe...Left Bank is driver side and right Bank is passenger side...both left and right upstream are sensors #1,,,and downstreams are #2...so drivers side is Bank 1: sensors 1(up) and 2(down)..passengers side is Bank 2: sensors 1(upstream) and 2(down stream)...
How do u know wish ones do I need to change whenever the code shows
Thanks!
Where did you buy the sensor ? An that was the upstream correct?
EHow to put up signs
Can I do at home on my own
Why did you just do the up stream and not the down🤔🤔🤔
Upstream are used for fueling downstream are for emissions.
Wish u would have shown yourself taking them out
Dw40 will help ur chair
how f*** do you unplug the wires? i cannot get the locking tab out. whats the trick? i even tried grabbing it with a pliers and yanking but its not coming out! i am about to just cut the wires and re wire my new sensor into the old wires that are sill plugged in!!!
I need the same question answered how do i get the wire and plug off??
@@mikiegayosso2149 I got mine off after trying again. What I found out is. If you’re doing this in your driveway on your back, the o my way you’ll be able to get BOTH hands up there to unplug the wire and plug it back in, you need to lay long ways under the truck... (head towards the front of truck, feet towards the back end) This made it way easier to bend my arms around the driveshaft and get both hands on the plug to un couple it from the harness. I was at first sliding under the truck sideways (head toward the passenger side, feet on driver side) doing it this way it only took me about ten minutes to replace the sensor. Oh and make sure you use a swivel adapter or a ratchet that flexes at the head. Hope this helps!!
you didn't show the removal or installation of anything...
I changed the 02 air sensor on my truck and it still don’t turn off
Have you disconnected the negative battery cable from the battery for at least 15 minutes? If that doesn’t turn off the service engine soon light disconnect both the negative and positive cables from the battery and, very *important*, with nothing connecting the battery cables to the battery or *ANY* power source, using a locking-plier(vise-grip) or c-clamp connect the two battery cables to each other for at least 120 minutes ( 2 hours ). If both of the previous procedures do not turn off the service engine soon code then you may have another DTC (Diagnostic Trouble Code) and you should scan the truck for codes again.
Why did you replace them?
Check engine light.
Happened on my Hummer
Are all 4 the same ones?
@@curtisleggett7121 - Are the downstream always the one to the rear of the vehicle?
@@thegreatecb The downstream oxygen sensors are either fastened into the catalytic converters or are after the catalytic converters. So, yes, the downstream oxygen sensors are the oxygen sensors closest to the rear of the exhaust system.
i have a 2000 sierria the holes to oxy sensors have a larger tread , the oxy sensor got a finer tread so do oxy sensors come with two different size tread? at 55 dollars for the upstream sensor and 70 dollars for the downstream i filed the treads on sensors which are aluminuim and forced the sensor into course tread hole and it does hold if you crank it tight so i don't know if sensor for seirria uses a different type sensor but sensor does work this half ass way. anybody had this problem ? input would be appreciated. ☺
Thanks for telling us to put the stuff on it, but not where to put it.
Do you have to reset anything after install?
It is recommended that you remove the negative cable to your vehicles battery before you unplug the O2’s connector and only reattach the negative battery cable AFTER plugging in the new or cleaned (old) O2 sensor.
I wanted a 2018
Video sucks, no good volume and we like to see the whole process!! Hello
What was it doing befor that and what code did it give you on scan ?
How many upstream and downstream?
2 and 2
two upstream and two downstream.
Which is bank 1 and bank 2
@@miguelgarduno935 bank 1 is driver side, bank 2 passenger side. Sensor 1 is before the catalytic converter (upstream). Sensor 2 is after the catalytic converter (downstream)
@@NikoDaDon Thank you
WD-40
Bro that squeak seriously
Nobody has dhown tje rrmoval of tjos sensor...you just skip the whole ordeal....and thats the part people want to see
which ones are bank 1 and bank 2 for those?
Bank 1 sensor 1(front)and 2(rear) are driver side, bank 2 sensor 1(front) is front and sensor 2 is at the back.
Is better to replace all 4
How many 02 censors does the Chevy has?
My 03 avalanche has 4
My 02 Avalanche has 4
2001 Suburban has four
Does this have any o2 sensors after the cat?
Ogtriple Og 1 after and 1 before per exhaust pipes, so in total you have 4 o2 sensors. 2 upstream and 2 down. Check if your vehicle was produced in Canada before you order, or look at the connectors, they sell 2 different types.
@@revonseepaul9292 what if u just got a single exhaust and y pipe
Will u only have 2
Im asking all this because im about to buy this truck that just has open headers right now so i got to figure out o2 sensors to get it legal
Yes 2 before 2 after the catS (2)
Mumble....Mumble....Mumble
But Thanks anyway.....
