How to Replace Bank 1 O2 Sensor on Lexus ES300, Toyota Camry, Solara and Avalon - P0420

[@h.nguyen6777]

I got code P1130 on my 2000 Lexus ES300 which is running 1MZ-FE engine as the one shown in this video so I needed to replace Bank 1 Sensor 1 air fuel ratio sensor. I did not want to get to it from underside because though it's located low but not low enough and also there is a cross beam that's obstructing access to it from underneath so I decided to attack it from top/driver side. I sprayed ton of WD 40 and ran engine for 10 minutes. Let engine cool for an hour so I wouldn't get burned. I am blessed with a pair of small hands so with a 7 dollar 22 mm open ended wrench from Home Depot, I loosened old sensor and tightened new sensor through the narrow gap between engine and firewall and with my left hand through a small gap adjacent to the throttle body I disconnected old connector and reconnected new connector. I was doing all this with my upper body flat on engine bay and doing it by total "feel" but what helped me was that I had removed/replaced the Bank 2 Sensor 1, the easy one, not every long ago so I knew what to expect when I was "feeling" my way around....I would suggest that if anyone needs to replace Bank 1 Sensor 1, you might well as well replace Bank 2 Sensor 1 first. If one fails the other one would fail soon after....Most of us usually would replace a pair of headlights at the same time, not just the left headlight or right headlight, right?

Clint, awesome video. A tremendous help. This is one of the most concise, explanatory and descriptive help videos I've ever seen. Sincerely, great job. You should consider getting on the radio for one of the car talk shows, you're a natural.

[@sammobleyscottsdalerealtor6985]

Well you saved me a lot of money with this video. I will say that my fat hands did have a tough time with the location.

Appreciate the positivity in the video! Very clear instructions and easy to follow. Gave me the confidence to attempt this with my dad.

Glad I could help.

[@sethster70]

Got a 1999 and parts store isn’t pulling up that part number, went ahead and ordered the one you had. They want to sell me a splice together universal fit on. 🤦🏼‍♂️ hopefully it works

[@davidmccreary9684]

If you have skinny arms this is super easy to change from the top, no need to jack the car up. I just got this car and this was the first time ever working on it, took 10 minutes to change this part from the top. I just removed the air intake resonator (black plastic box on big intake hose). Then I snaked a can of Kroil oil (with red tube on it) through there down to where the sensor is located, (use PB Blaster or whatever if you don't have Kroil). Then I re-positioned my arm to spray down the old sensor to hopefully penetrate the threads some (reach down through where you removed the plastic box). Then wait a bit for oil to penetrate some, while you're doing that reach down and unplug the old sensor, I had enough room to get both arms in there to make it easy. Then I used same kind of 02 socket as in this video and removed old sensor. Once that was out applied a bit of anti-seize to new sensor and just did the reverse of everything above. Might be wise to check and make sure new plug on new sensor is same as old one before removing everything, I did and it was a match. Total time was about 10 minutes for this job, I did it in a parking lot in 95 degree weather. Would have taken me longer than that just to drag out a jack, jack stands and all that nonsense not to mention crawling under the damn car. Now, if you have big Popeye arms this method may not work for you, but if you're skinny like me I really think this is the way to go as this was a super easy job. Of course I didn't run into any problems like stubborn connector or seized 02 sensor, everything went smooth. YMMV.

[@ClintHolland]

This is why we have kids. If you don't have the figure of a young woman like I do, ha ha, hire a kid with small arms.

[@drew6134]

Great video thanks for posting-this saved me $400 at the shop. I found it easier to replace it from the top driver’s side. Unless you have enormous arms or hands you should be able to perform this service just fine from the top. Old one was 20 years old, so a small shot of penetrating oil helped tremendously to get it off. 7/8” box wrench or crescent wrench will get this off and the new one on. Thanks again for posting!

[@ClintHolland]

Thanks for watching. Glad the video helped and saved you some money. That's why I keep making these.

[@formereverything4268]

Nice vid, Clint. Really told me what I needed to know to change out the O2 sensor in my 98 ES300. If you were able to get that electrical connector off by hand, you must have the strongest thumb in the world. I barely managed to get mine off with a pair of channel locks pinching down on that release tab. Once I got it, though, the rest was smooth sailing, just like your vid.

[@vshahid1001]

I am impressed at your ability to hold a camera steady and work at the same time. I suspect you are wearing some sort of a head mount, but then you couldn't see where the camera was pointing. So what's your secret? Of course, thanks for the instructions, I need to work on a 2000 Sienna that got error P0135 today, and I suspect it is identical to get to.

[@hoverlagrimas-mw2fg]

After you replace your new sensor oxygen sensor my question is my engine check is still on is that normal?

[@ClintHolland]

Yes. You will probably want to reset it either by using a meter or disconnecting the negative terminal. It may clear on its own given enough time as well.

Awesome. The hole won't hurt the price of RX300 1999 😄 I just need to fix it!

Wait so how many sensors is there total because my check engine light is on for this code in this video plus the p0430 code as well which is bank 2 sensor 2 if I’m not mistaken but I really need help choosing the correct sensors online and how many I’m supposed to replace. Thanks for any help. This car runs like a dream and has low miles for 02 and I’m planning on gifting this car to my mother once it’s running clean and clear with no CEL.

[@ClintHolland]

The V6 model has 3 sensors. 2 in the intake and one past the catalytic converter. So you are showing codes P0420 and P0430?

[@YeetPROD]

@@ClintHolland oh okay I see. Thank you. Yessir those are the codes and the car is running just fine. I went to get a quote at am exhaust shop to see what they could tell me he said it's the catalytic converter + the sensors. And it was gonna be about $1950 for it all done that's including labor. I told him I gotta think about it and come back when I got all the money ready.

[@YeetPROD]

I was hoping it could be a job I could do myself but idk I'm kinda handy but not like a certified mechanic either. And I love this car would hate to sell it just because of these 2 codes

[@ClintHolland]

@@YeetPROD In my opinion, I would replace all the O2 sensors first and then see if the catalytic converter needs replacing. Those O2 sensors are much cheaper than the catalytic and can be easily replaced at home.

@@ClintHolland that's what I was thinking originally thank you for your replies I really appreciate it. I can't figure out which sensors or part number I should say I need to replace them

[@linkedup7346]

I have a 2001 Lexus es300. I plan on keeping this car forever. Just replaced timing belt, water pump, spark plugs, drive belts, tensioners, etc. There is no other car advertised with the same luxury and condition of this car for sale under 25k. Anything I can actually afford has twice the mileage and morethanlikely needs 5-6 thousand dollars of work. I was smart enough to have this work done at a Toyota Dealership. I saved a cool 800.00 on per hour charges not having the work done at a Lexus dealer. Anyway, my check engine light has always come on after a few hundred miles of disconnecting the battery to clear the computer. Unfortunately this trick does not work for emissions purposes. There must be data in the computer for the test to be performed. I picked up a hand held scanner I now use to erase the codes which of course turns off the check engine light. The codes point to oxygen sensors, catalytic converter, and the like. This car never runs like there is a problem with the engine. It idles smoothly and is as fast as my 1985 Corvette. I would like to change the oxygen sensors one at a time to see if the check engine light stops coming on. The left bank and lean, rich adjustment are controlled by these sensors. Too bad a screw driver and a good ear don't work anymore to accomplish this. Those were the good old days...

Good Morning, I know this an old video , hopefully I still get a response. I have a 2001 Lexus Es300. With a Code P1135. I'm told it's the front sensor .which is bank 1 sensor 1. Could you please confirm

[@ClintHolland]

Thanks for stopping by. First of all, yes, P1135 does in fact refer to the Bank 1 Sensor 1 O2 sensor so that is correct. Secondly, and unfortunately, it is not the front sensor. The front sensor on this vehicle is Bank 2 Sensor 1. The one you need to replace is on the backside of the engine but is not that difficult to replace. Just watch the video above and you will be done in no time.

[@thelovelyannise6623]

@@ClintHolland I wish I could reply with the diagram from Lexus which states the opposite. It has heated o2 sensor in the back, and 2 a/f sensors in the front? Is the 01 model and 98 the same?

[@ClintHolland]

@@thelovelyannise6623 That diagram is wrong then. A heated O2 sensor would be labeled Sensor 2. Sensors labeled 1 are upstream sensors, not heated, and sensors labeled 2 are downstream after the catalytic converter and are heated. Bank 1 Sensor 1 is not a heated O2 sensor. The Lexus ES300 was the same vehicle from 1997-2001. Hope that helps. Here is a link to the diagram.

@@thelovelyannise6623 Ok, so now I understand the confusion. An A/F sensor, which just means air/fuel sensor, is basically the same thing as an O2 sensor. Some manufacturers call them A/F sensors and some call them O2 sensors. A/F sensors tend to have a wider range of measurement and are sometimes referred to as wideband O2 sensors. But mechanics just call them O2 sensors in general and most so will the auto parts store.

also I did the burp air bubble procedure for coolant system the coolant was not sitting in funnel with car off or on it just pour Right thru...no leaks thou,also fans seems to operate only in cold a/c with car running no hot air blowing

[@ClintHolland]

How quickly does your car overheat once starting?

[@KINGREED-NYC]

Clint Holland under 10 minutes

[@KINGREED-NYC]

Clint Holland I also notice my fans do not cut on unless u cut a/c on...

[@ClintHolland]

Have you checked the thermostat?

[@ClintHolland]

That can be pretty normal. Do you have any evidence that it is actually overheating other than the light on the dash? It could be your temperature sensor is broken and not correctly reporting the temperature.

[@angelzm6301]

do you know where is this sensor located?? i have a camry 2004 ,,(P0032 oxygen sensor heater control circuit high ( Bank 1 sensor 1)

[@AnNguyen-no7zs]

If you are under the car by the oil pan you see sensor next to it , that is bank 1 sensor 2 , from there follow that converter look up, there's another sensor that's bank 1 sensor 1 ( upstream) or you stand by passenger side wheel look down you'll see it little bit hard to get hands in there .. if you stand up in middle front of the car you see one sensor right next exhaust header that is bank 2 sensor 1 ( upstream ) from there go down is bank 2 sensor 2 ( downstream)

[@alalan3735]

Does this apply to the sensor for code P1130 on a 1998 Camry L4?

[@ClintHolland]

It sure does.

[@adrianrodriquez4802]

Clint, just to verify. I understand that one is upstream and downstream. I have a 1999 Lexus es300, and my error codes are P1133 and P1153. So my question is, both bank 1 sensor 1 and bank 2 sensor 1 require the same part?

[@ClintHolland]

They sure are These are both upstream sensors. The only different one is Bank 1 Sensor 2, which is the downstream, heated sensor.

[@tonymata2705]

hello so I have a 2001 solara but it gives me the P0340 code and I already replaced the camshaft sensor and the code still on any suggestions

[@ClintHolland]

If you reset the MIL, how quickly does it come back? And are you having any symptoms consistent with a bad sensor? Or just getting the code?

[@tonymata2705]

well it takes about 10 seconds then will come back on and its only P0340

[@ClintHolland]

Does the timing belt look ok? This can be caused by several different things from the timing belt, a defective starter, problems with the water pump, or just an issue with the sensor or its wiring.

[@toddvance1979]

This is actually way easier to get to from the top!, Just take the air plenum off first.

[@ClintHolland]

If your hands are big it might be worth going that route. If you have girl hands like me this way is pretty easy. Or bribe some kids to help.

[@williamjohnson2569]

Clint Holland what was the name of the tool you used for the 02

[@shaunlambertii79]

O2 sensors are 22mm, not 7/8... just for future reference or anyone else planning on doing this at home.

[@ClintHolland]

True. But many if not most O2 sensor removal sockets actually list their size as 7/8 and the actual difference between a 7/8 and 22mm is 9 thousandths of an inch which is pretty irrelevant in the grand scheme of things. And many times, depending on the age and corrosion of an O2 sensor, you will actually have to drop down to a 21mm or 13/16 socket to get a tight fit. But now I am just being pedantic. Thanks for watching.

[@nancyreyburn8156]

Sorry Clint, No wonder looks different because it is. I was checking for Knock sensor. I just watched other video.

[@ClintHolland]

No problem Nancy. Maybe I will produce one on the knock sensor soon.

[@KINGREED-NYC]

can this sensor being bad cause car to overheat

[@ClintHolland]

Very doubtful. A bad sensor can cause excess heat generation but highly unlikely to cause it to overheat. I assume you have checked the normal stuff like the coolant and radiator cap and thermostat?

[@dandolan3856]

Well Done!

[@galloslacrianza]

[@CircleOfSignfighters]

I appreciate you making this video but the actual OEM parts numbers would be fantastic. I'm having trouble verifying this information between Rockauto, Clublexus, and LexusPartsNow.com

[@ClintHolland]

Absolutely. I bought these from Rockauto and I just typed in "1998 Lexus ES300 O2 Sensor" and then found the ones that said they replaced Bank 1 Sensor 1. In this case it was the NTK 24594. Hope that helps.

[@CircleOfSignfighters]

Excellent, thank you so much. For reference to those that come later the code I pulled from a 2000 ES300 was P1135 Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1).

[@ricksivley7047]

I didn't know you ever back the camera way so we can see where the sensor is. I have no idea where to look because it was a close up shot the complete time. I'm not a mechanic, that's why I'm looking on KZbin and now I have to go to another video hoping to locate the sensor

[@ClintHolland]

I describe where it is located at 45 seconds and at 58 seconds I follow the exhaust pipe from the front of the car to it so you can see where it is located. Sorry if that didn't help you find it.

[@AnNguyen-no7zs]

That looks like you removed the bank 1 sensor 1 .. bank 1 sensor 2 is under by converter next to the oil pan ..

[@ClintHolland]

Correct. This is bank 1 sensor 1. I also have a video for bank 2 sensor 1 but I don't have one for sensor 2.

[@LXRD-SUPREME-]

@@ClintHolland greetings and thanks for the awesome video i have a 2003 es300 showing code p0134 . Do you have denso part number ? I just changed both knock sensors and harness with genuine lexus dealer parts $670 for parts and $250 for labor. I dont have as much money for this job plan on getting denso aftermarket

[@ClintHolland]

@@LXRD-SUPREME- Looks like is 2349042. Check out www.RockAuto.com to be sure but that should be the sensor for Bank 1 Sensor 1.

[@LXRD-SUPREME-]

@@ClintHolland thanks i appreciate your response. Take care ✌

[@stephen285]

much appreciated

[@ClintHolland]

You are welcome.

[@Tai-tenku]

Why replace o2 sensors? You should described the problem symptoms.

[@ClintHolland]

The symptoms of a bad O2 sensor are in the video description as well as the Diagnostic Code being in the video title.

[@EsDACcompany]

Do you know where about LEXUS ES 330's O2 Sensor Bank 1 Sensor 2? Thanks.

[@ClintHolland]

+EsDACcompany What year 330?

[@EsDACcompany]

What you posted is Bank 1 Sensor 1. (Sensor mounted before one of the three catalytic converter). Bank 1 Sensor 2 must be located after catalytic converter. (I believe on my own research through googling it).

[@jasonoechsle9522]

same procedure really. but the connector is under the drivers seat, I beleive. the b1 s2 will be after the the catalyst.

[@elguerokabron]

Its just unplugging it & screwing it back together & they want to charge 300 plus at shops 🤦🏻‍♂️

[@ClintHolland]

In this case that would be a ridiculous amount. However, some O2 sensors are a nightmare to replace and that would be a reasonable amount.

[@elguerokabron]

@@ClintHolland yea i have this same exact car and a while back at the lexus dealer they wanted to charge alot more then 300.

[@elilopez2517]

Isn't that bank 1 sensor 1?

[@justinthyme7275]

Use anti-seize for the next time to keep it easy to replace.

[@ClintHolland]

Agreed and most O2 sensors come with it already on the threads but even that doesn't stop this issue on a 20 year old car.

[@ritayeechow]

I went under the car, but I'm not sure if that's the bank 1 sensor 1. I'm afraid u doing the downstream sensor.

[@ClintHolland]

The downstream sensor is completely different. It is a heated sensor and is in the exhaust system.

[@ritayeechow]

The one I found is in the middle of the car... It said it's bank 1sensor 2 www.clublexus.com/forums/attachments/es-1st-to-4th-gen-1990-2006/130713d1222189638-99-es300-o2-sensor-or-air-fuel-ratio-sensor-01-o2-sensor-position.jpg But it looks like the sensors in your video... So it must be upstream?

[@ritayeechow]

Does the downstream sensors also located under the car? I replaced the bank 2 sensor 1, thanks to your other video. Mine is 2000 Lexus es300

[@ClintHolland]

Correct. It is in the exhaust system after the catalytic converter.

[@ClintHolland]

The downstream sensor is in the exhaust pipe after the catalytic converter.

[@kimchee94112]

Bank 1 sensor 1 is a pain to remove. It's frozen and no room to get to, no can do today. I just cut a slot on my 7/8" box wrench with a cheater bar and have another try tomorrow. Toyota engine designer(s) should be shot.

[@kimchee94112]

I have no idea what is more PIA to remove: this sensor or the Honda crank bolt. Will find out tomorrow.

[@ClintHolland]

Good luck. PB Penetrant is your friend.

[@jaredmac11]

Cant even get my hand in there... what a pain in the ass.

[@ClintHolland]

Thankfully I was blessed with woman sized hands. Or maybe that isn't a positive quality.

[@brandonevans4142]

There's no way to get to this if you have man sized arms & hands...guess I'll hire a 10 year old

[@ClintHolland]

I can't argue with you on that one. I was "blessed" with girl hands I guess.
