Dude I've been a Master Tech for close to 40 years and I ran across your video and had to watch this for some reason. You did an absolutely amazing job of describing the sensor system. Bank 1 is always where your number one spark plug is. I have tried many many times to explain that just because a code comes up for a sensor doesn't always mean that the sensor is bad. always check your connection as many times all I've had to do is unplug the sensor then plug it back in clear the codes and see if it comes back. anyway, keep up the good work and keep doing it yourself
Thanks Frank. I have a 2013 Toyota Venza (V6 3.5 L engine) and I suspect it is an O2 sensor problem. Don't want to go to the dealership. Your video has helped me a lot and I am going out to buy a scan tool and trouble shoot the problem. Great video and very honest. Much appreciated.
You say very humbly that you aren't a mechanic, well l say that you are, you show a deep understanding of, and solution for, what mechanics have to resolve and deal with every day. Thanks for your common sense solution to a common problem for people out there that don't know. From this old mechanic of many years. 🌈
Good on you for having the courage to do the job yourself. I bet the feeling of self sufficiency is very satisfying . Thanks for passing on the information.
So glad I found this video for an explanation of the sensors alone! I got error code p0051 and that gave me an issue with Bank 2 Sensor 1. Now I know that it’s driver side and upstream from the cat! I gotta order the part and I’ll update when I get it all together! Thanks again!
Thank you Frank! I like you who do not know anything about O2 stuff. Paid a lot of money for new ones and to mechanic for replace the old ones, "Check Engine" light still back on after few days. I decided educated myself and change them by myself.
This video popped up "recommended". So I watched full view. Helpful content. As a non mechanic DIYer (been a DIYer before DIYer was a thing LOL) I often have to do some research. Unfortunately been given wrong advise way too many times. The anti-seize will save you some future headaches. Just a DIY tip, I use 50% acetone/ 50% transmission fluid to help free rusted sensors, bolts etc. Found it to be as effective as any rust bustor that I bought, always handy & less expensive. Added another 👍 to the 5.7k you already received. Nice job. Stay well, Joe Z
This is awesome! Thanks Frank, I am only left with one doubt and I have been doing my homework and still can't be 100% sure of the answer. I understand there is the upstream and downstream 02 sensors, however, is the right hand side same as left hand side? Just to be clear, I know the downstream is different from the upstream, simply wondering if I just buy two of each to swap all fours
For not being a mechanic, you did very well! Denso all the way with Toyota, Bosch for anything German, A/C Delco for GM, Motocraft for Ford. Definitely go with Rock Auto for any parts that you need. Kudos! :)
Thanks, Dude. Parts Geek actually has Oxygen Sensors for around $ 40. Look into it. Spray the crap out of your old one , let it set for 10 minutes. Don't gall the threads getting the old out. Put anti seize onto the new one prior to installing.
I got a P0420 code that is bank 1 sensor 1. It's the upstream sensor on the passenger side. Got an ntk sensor because it was available at Napa. Code came back on after 3 days.
make sure where your banks are first before removing any sensor. I have a 06 Tacoma with a V6 4.0 L engine. Autozone told me my bank #2 was on the passenger side (right side) of the truck. I installed a new sensor on the passenger side. the engine light and code continued you show up. I came to find out bank #2 is on the drivers side (left side) of the truck, IT IS NOT ON THE RIGHT SIDE. On the V8 4.7L engine, bank #2 is on the passenger side, but not on the V6 4.0 L. The people working at auto part stores are helpful but they are not mechanics. Thank you for your helpful video, Frank.
Like I mentioned in the video, I too experienced a similar situation. Have to be careful about that- the same thing happened to me as well. Very frustrating. Thanks for your comment
These engines have premature failure of the head gasket(atleast mine did). This caused my o2 sensor to fail. If water is getting by the head gasket and out the tailpipe it will ruin an o2 sensor. So if the o2 sensor keeps failing it could be a head gasket.
Here's a hot tip to figure out your number one cylinder, it is the one that is at the Leading Edge of the engine. How can tell? Spark plugs and fuel injectors are offset. Whichever one is closest to the front of the engine is number one.
I’m getting ready to do this job on my 07FJ cruiser are you able to access both sensors from the engine compartment? Or do you need to get under the vehicle? Thanks

@@jodiehighroller9820 worked! Got it at O’Reillys for 70$ just make sure you know whether you need an upstream sensor or a down stream sensor there are 2 dif ones depending on how far down the exhaust pipe it is
It is a very tight fit - it took me a while to get a hand on it and use my thumb to push that tab down - it’s really important to hit that “tab” I mentioned in the video to unlock the connection
Please sir and anyone who can help me please i need your help,i have a Chevrolet spark American type 2013 model i have a problem on it wish i have changed a lot of things but still giving me the same problem, the problem is lower acceleration, please what i do to stop this problem
I have perhaps two days more experience than you with auto repair and had the same problem come up on my Honda CRV recently. I managed the replacement after watching hours and hours of video in preparation. Now I find yours that is superior to 90% of what I watched. Just wanted you to know and be encouraged to carry on making instructional videos. The more I study on RUclips, the more I’m convinced that being able to make a really good video is some kind of gift, and quite rare.
Check engine light came one. Ran the code. Took truck in for an estimate, it might be this, it might be that. F**k that. Watched your video and grew some balls to do the work myself. It was an O2 sensor. Thank you for the tips. It worked. Now I can buy more gun parts with the money I saved. You da man!
Thank you very much! As a single female this stuff can be very intimidating and unfortunately unknowledgeable people get taken advantage of so thank you thank you helped me more than you know!
This is why I like working on people's vehicles and teaching them as I work on the vehicle, I like passing knowledge on so people don't get taken advantage of......
Great video Frank. Very straightforward. The left bank/right bank explanation was helpful. Just finished doing the two upstream sensors on my 2011 Tacoma V-6 4wd. I bought my Denso sensors from Amazon. Same price as Rock Auto but free and quicker shipping. I didn’t know that the chain auto parts stores might do price matching until you mentioned the deal you got from O’Reilly. The hardest and most painful part of the job is reaching and disconnecting the wire connectors.
You pretty much just paraphrased the entire video. Thanks for the compliment and I agree that is definitely the hardest part. Thanks for watching Brian
I've done most of the work on my own cars since I started driving cars, which is closing on 40 years. I currently drive a 2013 Kia Soul, which has direct fuel injection, and I discovered my main problem on the fuel side. Any car which uses direct fuel injection is going to have a [version of a] device mounted somewhere on the valve cover, which is called a High Pressure Fuel Pump. And this is my helpful story: Leaving the house, my car car starts choking and won't accelerate at all. I can start it, but it only stays running at idle, so I limp it back to the house. I was getting codes for running rich, and for a faulty catalytic converter. Check O2 sensors (mine is 4-cyl, so only two OXY. sensors), they're old and bad. Replaced the O2 sensors. Checked for exhaust leaks, found two small ones and patched them. Car runs again, but still showing the same codes, and still getting the smell of unburnt gas, a.k.a. running rich = too much fuel. No vacuum leaks found. Start investigating the fuel system. I disconnected both bat. terminals, then disconnected the pump. Upon removal, I quickly discovered that my High Press. Fuel Pump was leaking down into the valve cover. There is a heavy spring on the bottom of the pump, which is actuated by the camshaft. Between the pump spring and the camshaft is a part called the 'follower', which has a roller bearing on the bottom, and which is what actually pushes against the spring mechanism to drive / actuate the pump. (This bearing 'follower' is going to be replaced, also. If it fails and sheds debris inside the valve cover, it could easily cause major mechanical damage to the valves and the motor.) Also, when the bearing gets worn and starts to get some play in it, it makes a rattling noise that sounds like valve lifters knocking. Because the fuel pump is leaking from the bottom, and into the valve cover, there are fuel vapors from unburnt fuel building up inside the valve cover. The fuel is also mixing with my oil and thinning it out, wrecking the viscosity of the oil. If my car hadn't chocked out from failed sensors, I might not have discovered my fuel pump issue in time to avert larger problems. If you have a vehicle with direct fuel injection, and you're smelling gas, and the car is throwing p-codes that it's running rich, or the cat. converter has failed, pull the high pressure fuel pump and check if it's leaking down along the spring into valve cover body. If it is, replace it asap. I would strongly recommend installing a new follower bearing, as well. Point is, the codes don't always tell the whole story, or always help to determine the best way to begin your trobleshooting / diagnosis, because the codes are not always giving the full picture. Granted, the scanner I used I borrowed from my brother, and I wasn't overly impressed with its available features. Start by checking those things which only require a few tools to remove and diagnose, and the cost of a little time and elbow grease. Like the working condition of your high pressure fuel pump, for example. My codes said exhaust leak, faulty fuel pressure sensor, bad cat., and none of those were the principle issue. A multi-meter is an essential tool to test and troubleshoot the performance of many components on your car.
that's what I did bought 4 on ebay but haven't installed them bc the problem was solved w SEAFOAM in the gas tank so well just sit on them till we really need them
Great video, pal, and I do mean GREAT. You covered everything necessary for a sensor change and then some. Disregard those 'thumbs down' complainers, they are lame. You were as good as ANYONE I've ever seen.
!!!!!! Yep I Agree !!!!! Good comment. I'veseen a lot of YT vids Very few ( there are some ) are this well done. You here, "this thing here. Put that thing there." And you can't see anything on the vid bc of bad camera work. And some vids like that are done by mechanics.
I do not know why 56 people gave this video a thumbs down. I have watched many youtube car repair videos and this is one of the best ones. BTW im a tech at a hyundai dealer and yes always use the factory oem 02 sensors grate job on this video Frank and thank you
Thanks Frank, that was alot of help. I appreciate you taking the time to show us non mechanics doit yourselfers. I got jeep liberty saying bank 1 sensor 2. So I'm assuming that's driver side downstream. Wish me luck and thanks again. Great job
I just replaced all 4 of my 02 sensors for the price of $136. Borrowed the tool from my local auto parts store and did it right in my driveway. Dealerships and chain auto repair shops was quoting me around$237-400 to replace 1 sensor, just for labor. I never pay anymore to work on my vehicle when I can do the job myself
@@RUclipsiscool865 The O2 sensors that have been working as well or better (might be exactly the same) as OEM are $45 and $47 respectively) are Denso on Amazon for my Tundra. Likely similar for the Taco. Bought anti-seize and a tool similar to that in video as well, inexpensive. Even adding the cost of the OBD2 reader, the whole lot costs less than one O2 sensor replacement at the stealer-ship. And now I'm ready if they ever again pop up.
You are a natural. Great camera work, great presentation and I learned a lot. I have an oxygen sensor to replace and an air charge temperature sensor if I can find it.
@@ahubert285 Not yet, I got installed a new good brand new downstream O2 sensor from NTK and it didnt work. Now I got me a Cat and a A/F sensor for bank 1 to get it install sometime next week hopefully that will fix it.
Great video I have a 2003 Toyota Tacoma love my truck. It’s burning lots of fuel. Could this 02 sensor do it? Changed air filtre plug 30 k km ago? Anyone out there can you help?
Yes. Is your check engine light on? Get the code scanned, some autoparts places will scan for you. The code will tell you the problem sensor. It might be something else (vacuum line tc). When my sensors went bad I could see the needle on my gas gauge slowly going down and it ran rough.
I learned bank 1 is passenger side the hard way too. In case anyone is wondering, P0420 is bank 1 downstream sensor, P0430 is bank 2 down stream sensor.
And may I say one more thing. Although your car may be com- pletely driveable with a faulty sensor---your gas mileage will decrease, AND, you can damage your 'converter...Not good!
Rock Auto is my best friend & I as a retired Mechanic gives this Frank 100% Passing mark!! Like he really said DO YOUR HOMEWORK!! You got my Thumbs up Frank!! ;👍👍👍👍👍
Never take a spark plug or O2 sensor out while hot. It will warp the threads and you’ll have to rethread which is a bigger pain in the ass. Just saying
Can't Beleive they matched your price. I have a Chevy Silverado. There about $90 a piece. I also have 4. Mine started running terrible. Had the same code. So i pulled them. They were terrible. So i replaced with Amazon 02 sencors. They worked great. Only for about 2 months now the same code. They are cheapos. Have to get name brand ones i guess
Before you order or buy a replacement sensor, Always check it first! I have unplugged them and plugged them back in and not had any more issues and I've unscrewed them, cleaned them up and re-installed them without any more issues!
To release the connector, first push the connector closed tight, push down on the tab at the very back of the female connector whilst pulling on the male connector. If you're removing your old O2 sensor, you can pull on the cable as it doesn't matter if you put stress on them.
Thanks Frank, I found this video interesting, easy to follow and helpful. I found it helpful that you showed the two sensors on cam so now I know what to look for. Just wish you would have explained where on the truck the plug in connector went to.
I believe sensor end of the O2 sensor screws into the exhaust and the wires should plug into a connector which will lead back to the ECM (engine control module or the 'brain'). Hope this helps
I don't know why, but it seems no US supplier has ever heard of what they call 'difficult access sockets' in the UK. They work on any wired/threaded sensor AND are good for tubing fittings that are nested in where you can't really get a normal flare wrench on it or even a crowfoot style. A basic set contains 10, 11, 12, 14, 17 and 19mm sizes and from what I found costs roughly $30 to $50, depending on where you source it from. Diesel mechanics are the ones most likely to benefit from a set, but I had reason to need one just recently [11mm, lightly massaged with a stone to fit standard/imperial] to work on a set of front drum brakes on a car built in 1971 where the spindle really got in the way]. I don't really recommend taking a dremel tool to a typical deepwell socket, as it may not last long or perform well due to insufficient thickness - they really do depend on the wall being unmolested.
We had an oxygen sensor code pop up from time to time on our Honda accord. It turned out to be valves not seating & oil was getting on one of the spark plugs putting oil into the exhaust throwing off the sensor. One way to check for this is look at your plugs also light smoke out of exhaust.

One question how did you know you had to replace oxygen sensor? Just want to replace it so the truck can run better?
He got a check engine light code display on his dash. He used his OBD II scanner to determine that it was for a bad o2 sensor.
@@eyesalooking Thank you.
In RHD Tacoma, bank 1 is the driver's side.
You can get a 'universal' one for a lot less! maybe $30 - although you will probably have to change the plug.
If its not an "air fuel ratio" oyxgen sensor it won't work for my vehicle
Hey thanks 🙏
Use die electric grease for connect ors
In most vehicles with two rows of cylinders, Bank 1 is on the driver's side, just like Piston 1.
Rely on a manual. Online info is not always accurate.
can you just use an open end wrench?
prob not due to clearance

Assalam alay kum Muhammad Farhan
Finally someone who is honest! I'm about to change all 4 of mine. Has 145k and never changed them. I appreciate the advice and honesty.
For someone who is not a mechanic, you did excellently. Thank you
Thanks Frank, that was alot of help. I appreciate you taking the time to show us non mechanics doit yourselfers. I got jeep liberty saying bank 1 sensor 2. So I'm assuming that's driver side downstream.
Wish me luck and thanks again. Great job
Great job explaining from start to finish. Much appreciated
Good video! You have a nice, calm delivery. You got lucky with easy access, some are horrible to replace.
thank you
I just replaced all 4 of my 02 sensors for the price of $136. Borrowed the tool from my local auto parts store and did it right in my driveway. Dealerships and chain auto repair shops was quoting me around$237-400 to replace 1 sensor, just for labor. I never pay anymore to work on my vehicle when I can do the job myself
I love hearing stories like this. You and I think the same Webster . Good work 👍
Where did you buy the sensors that cheap??
@@RUclipsiscool865 The O2 sensors that have been working as well or better (might be exactly the same) as OEM are $45 and $47 respectively) are Denso on Amazon for my Tundra. Likely similar for the Taco. Bought anti-seize and a tool similar to that in video as well, inexpensive. Even adding the cost of the OBD2 reader, the whole lot costs less than one O2 sensor replacement at the stealer-ship. And now I'm ready if they ever again pop up.
You sure the upstream sensors you got are air/fuel ratio sensors? They do cost a bit more than cheapo downstream O2 sensors.
You are a natural. Great camera work, great presentation and I learned a lot. I have an oxygen sensor to replace and an air charge temperature sensor if I can find it.
Awesome to see someone who really wants to help others, God bless you man for a great video..
Which OBD will tell you specifically which sensor it is. Upstream or downstream because I only get the code P0420 and it just say on bank 1
Did you ever resolve this issue? My ‘06 Tacoma has the exact same code and same bank 1.
@@ahubert285 Not yet, I got installed a new good brand new downstream O2 sensor from NTK and it didnt work. Now I got me a Cat and a A/F sensor for bank 1 to get it install sometime next week hopefully that will fix it.
Good job with the DIY as somebody will be very appreciative out there.....Good stuff....
Thanks Scott!!!!
10 out of 10 very precise. I'm not a mechanic myself but I do fix my own problems. Thanks Guy all the way from Cape Town South Africa
thanks for watching!
Great video
I have a 2003 Toyota Tacoma love my truck. It’s burning lots of fuel. Could this 02 sensor do it? Changed air filtre plug 30 k km ago? Anyone out there can you help?
Yes. Is your check engine light on? Get the code scanned, some autoparts places will scan for you. The code will tell you the problem sensor. It might be something else (vacuum line tc). When my sensors went bad I could see the needle on my gas gauge slowly going down and it ran rough.
I learned bank 1 is passenger side the hard way too. In case anyone is wondering, P0420 is bank 1 downstream sensor, P0430 is bank 2 down stream sensor.
And may I say one more thing. Although your car may be com-
pletely driveable with a faulty sensor---your gas mileage will
decrease, AND, you can damage your 'converter...Not good!
Rock Auto is my best friend & I as a retired Mechanic gives this Frank 100% Passing mark!! Like he really said DO YOUR HOMEWORK!! You got my Thumbs up Frank!! ;👍👍👍👍👍
Never take a spark plug or O2 sensor out while hot. It will warp the threads and you’ll have to rethread which is a bigger pain in the ass. Just saying
Can't Beleive they matched your price. I have a Chevy Silverado. There about $90 a piece. I also have 4. Mine started running terrible. Had the same code. So i pulled them. They were terrible. So i replaced with Amazon 02 sencors. They worked great. Only for about 2 months now the same code. They are cheapos. Have to get name brand ones i guess
Yes the name brand ones make all the difference. Whatever is in your silverado - get the same brand to replace them with.
Dude, all ya' have to DO is go on RUclips and ask a question.
Before you order or buy a replacement sensor, Always check it first! I have unplugged them and plugged them back in and not had any more issues and I've unscrewed them, cleaned them up and re-installed them without any more issues!
To release the connector, first push the connector closed tight, push down on the tab at the very back of the female connector whilst pulling on the male connector.
If you're removing your old O2 sensor, you can pull on the cable as it doesn't matter if you put stress on them.
Nice job, appreciate you making this video to us diy guys.
Thanks Frank, I found this video interesting, easy to follow and helpful. I found it helpful that you showed the two sensors on cam so now I know what to look for. Just wish you would have explained where on the truck the plug in connector went to.
I believe sensor end of the O2 sensor screws into the exhaust and the wires should plug into a connector which will lead back to the ECM (engine control module or the 'brain').
Hope this helps
I don't know why, but it seems no US supplier has ever heard of what they call 'difficult access sockets' in the UK. They work on any wired/threaded sensor AND are good for tubing fittings that are nested in where you can't really get a normal flare wrench on it or even a crowfoot style. A basic set contains 10, 11, 12, 14, 17 and 19mm sizes and from what I found costs roughly $30 to $50, depending on where you source it from. Diesel mechanics are the ones most likely to benefit from a set, but I had reason to need one just recently [11mm, lightly massaged with a stone to fit standard/imperial] to work on a set of front drum brakes on a car built in 1971 where the spindle really got in the way]. I don't really recommend taking a dremel tool to a typical deepwell socket, as it may not last long or perform well due to insufficient thickness - they really do depend on the wall being unmolested.
I’ve never heard of them before. They sound useful. Thanks for the info
👍 this guy has a servants heart ! He'd pull over and change a tire for a lady good man, God bless him !
An not just for a pretty lady lol 👍
Good job on the video! I refuse to use rock auto anymore! Horrible shipping debacle in the past and no easy way to get it resolved.
Over time I've like to disconnect battery prior to working with anything electrical. Any body like to share?
Dude, I like your intro. "I like saving money"... Makes sense to me.
Thank you Frank !! I like saving money too !
Bullseye! Straight into the heart. Thanks a lot man. You saved my nerves and made my life better.
We had an oxygen sensor code pop up from time to time on our Honda accord. It turned out to be valves not seating & oil was getting on one of the spark plugs putting oil into the exhaust throwing off the sensor. One way to check for this is look at your plugs also light smoke out of exhaust.
Great explanation for beginners, great job & God bless.
