Ok first of all, to the author of the video…ABSOLUTELY PERFECT AND HELPFUL INFORMATION so thank you very much. Don’t worry about some of the comments made to you because you’re covered more than the basics. By the way to those whom commented, simply reading or watching the video and to the author of the video; The code that will tell you this needs to be replaced will always be P1155 and sometimes P0155. This is the upstream sensor Bank 2 Sensor 1. There is an identical sensor behind the engine block that will give you a different code, and not as easy to reach and/or change but certainly manageable. I guess you could call that one the downstream sensor. I hope this information helps everyone. Those codes generally cover fourth generation Camrys 97-01. PS…. It is very important to note when purchasing this sensor, you will need the wideband version which is quite expensive regardless of where you purchase it. Certainly $120 or more and as much as $300. Denso is the highest of quality and best priced one to buy. I PROMISE YOU, if you go to the local auto stores and tell them you need this air fuel sensor (it can be called oxygen sensor) they will sell you the wrong one and you’ll think you’re getting a great price which is the narrow band which is “Not made” for the V6 3L cars.
Ps…one more thing, I believe it’s 22 mm and if you do it just right you can slide the round end of the wrench over the wire connector all the way down to the nut that needs to be unscrewed.
To be honest with you, when you use a crescent wrench, you are supposed to have the pressure applied to the stationary part of the wrench, not the moveable jaw of the wrench. When you tightened the thread you should have flipped the wrench backward so the pressure goes against the nonmoving part of the wrench head. Otherwise, you can strip the nut with the wrench. There are a right way and a wrong way to use the crescent wrench. Strip enough nuts and you will learn.
Cool, I was not aware of this but makes sense. Common sense is not that common atleast in my use of the crescent ranch. Thanks for the tip will do this proper in the future.
I'm about to do this exact thing for my 98 camry. So the wd40, does it just make it so the nuts come off more easliy? but spraying it on the sensor, isn't that a bit dangerous? did you have no problems?
It depends on the code you are getting. P1135 code is mostly related to O2 sensor upstream. If it’s down stream sensor, It may be have a different code I guess, I don’t know. A cursory google search is saying they will have different code. But, it’s a roll of the dice. If it’s upstream sensor it’s easy to replace. If it’s downstream, it better to get a shops help to replace the sensor. Hope this helps!
Engine idling will not be consistent. Eg. If you are stopping at an red light and your engine idle is not smooth at near 1000 rpm and you see it going slightly up and down then your air fuel sensor is bad and it's not working properly. Thanks
You don't, until you get a check engine light saying something is wrong with the sensor. If you are taking about preventive maintenance for the O2 sensor, then I suppose you may replace them every 60,000 miles, but since the car computer tracks and complain on O2 sensor malfunction, I would consider the replacement of the sensor every given interval a luxury rather than a necessity. Thanks.
Sounds like an issue with downstream air fuel sensor. I replaced upstream air fuel sensor in my video. Downstream sensor is near catalytic converter underneath the car. Please check your downstream oxygen sensor. Hope you resolve your issue. Thanks for your comment. Please let me know if you need more info. Cheers.
Feedback loop fix's Finally figured it out! I had a clogged vacuum port on the throttle body that was causing P0401CEL. Once I thoroughly cleaned the TB, no more CEL. Also replaced the A/F sensor, with no further issues. Passed the dreadful California emission check with flying colors. Once again, thanks for the video 👍
I got my first one from eBay, unfortunately it didn't work properly even though the part number matched. I later bought my sensor from a local AutoZone and it worked. So eBay didn't work for me.
@@feedbackloopfixs9503 yeah and ebay price vary around 20-100$ which is huge difference. I think im gonna stick with Amazon.. thanks for your video very helpful
@@feedbackloopfixs9503 Are the aftermarket sensors okay? That’s what they just put on mine. I’m hoping it’s okay. It’s a 2000 Toyota Camry. I thought it would be pretty simple for a mechanic. 🤷🏼♀️
@@anitabreakone Yes, Aftermarket sensor will be fine. It should be a quick job for a mechanic to replace this sensor than if you do it by yourself, but they still will charge you for an hour's worth of labor I guess.
I haven't heard that specific code but it seems Bank2 Sensor 1, same as the one in the video. Don't know if that all it needs but does need to replace air fuel sensor like in the video. Thanks
The sensor I replaced in this video is upstream O2 sensor. You may find one more O2 sensor near the catalytic converter underneath the car exhaust, but it's called a downstream O2 sensor. May be you are referring to that as upstream rear I guess. Thanks
@@feedbackloopfixs9503 my problem is the air fuel/ratio sensor on bank 1 sensor 1 on my Toyota Camry 2002 se 6 cylinder I wanted to know if you shed any light on where is this the upstream front or upstream rear ????
@@b-lou296 Hello, Bank 1, Sensor 1 is upstream sensor. It's the same sensor I replaced in my video. O2 is same as air fuel ratio sensor. Make sure you buy the right replacement sensor for 6 cylinder version of Camry. I first bought a sensor from ebay, unfortunately after installing I found its not working properly and had to buy the right sensor from a local auto shop. Thanks.
@@feedbackloopfixs9503 I am looking at one right now is their a way I can contact you so I can show you the pictures if you don’t mind i really appreciate it Instagram or Snapchat ? Anything
I got code - P1135 which is upstream oxygen sensor problem which is found near the engine exhaust outlet. Your code - p0420 seem to be related to downstream oxygen sensor issue which is found near the catalytic converter under the car near the exhaust in the back.

arent oxygen sensor and the the Air fuel ratio sensor two diff sensors?
Question How Do I Know If It’s The Censor After The Catalytic Converter Or This One You’re Doing Here ?
I Have A 2001 Also With Code P1135 But My Reader Just Says :
P1135 : Manufacturer Control
It depends on the code you are getting. P1135 code is mostly related to O2 sensor upstream.
If it’s down stream sensor, It may be have a different code I guess, I don’t know. A cursory google search is saying they will have different code.
But, it’s a roll of the dice. If it’s upstream sensor it’s easy to replace. If it’s downstream, it better to get a shops help to replace the sensor. Hope this helps!
@@feedbackloopfixs9503 Ok thanks ill replace this one and see if the check engine light goes off , I’ll be back with an update this weekend 🤞🏾.
what are the likely signs of a bad air fuel sensor?
Engine idling will not be consistent. Eg. If you are stopping at an red light and your engine idle is not smooth at near 1000 rpm and you see it going slightly up and down then your air fuel sensor is bad and it's not working properly. Thanks
also OBD error p1135 is bank 1 sensor 1 (upstream sensor)
How do you know when to replace the oxygen sensor
You don't, until you get a check engine light saying something is wrong with the sensor.
If you are taking about preventive maintenance for the O2 sensor, then I suppose you may replace them every 60,000 miles, but since the car computer tracks and complain on O2 sensor malfunction, I would consider the replacement of the sensor every given interval a luxury rather than a necessity. Thanks.
My OBD code is P2238 "Bank 1 Sensor 1 Oxygen Sensor".
When I search for part should I look for "downstream"? or "upstream"?.
Sensor 1 means it's upstream. Look for upstream Oxygen sensor when you are searching for parts. Thanks
I also have the dreadful P0401 ever insufficient flow and P1113 A/F sensor. Any suggestion will be appreciated.

Did you buy this one on AutoZone?
Yes, the one I bought from Amazon did not work as it was for 6 cylinders I guess. AutoZone parts worked for me. Thanks
@@feedbackloopfixs9503 I tried to buy it from AutoZone but they don't have that part number
Where did you buy the replacement? Oem or ebay? How did it go
I got my first one from eBay, unfortunately it didn't work properly even though the part number matched. I later bought my sensor from a local AutoZone and it worked. So eBay didn't work for me.
@@feedbackloopfixs9503 yeah and ebay price vary around 20-100$ which is huge difference. I think im gonna stick with Amazon.. thanks for your video very helpful
How long does this take?
I would say it will take somewhere about 1 to 2 hours to replace this sensor and to check if everything is working as expected. Thanks
@@feedbackloopfixs9503 thank you.

Where is the upstream Front? And where is the upstream rear on the Toyota camry please help me
The sensor I replaced in this video is upstream O2 sensor. You may find one more O2 sensor near the catalytic converter underneath the car exhaust, but it's called a downstream O2 sensor. May be you are referring to that as upstream rear I guess. Thanks

you forgot the heat shield
Is the code P0420?
