03-07 Accord O2 Sensor Replacement, P0141

- เผยแพร่เมื่อ 16 ก.ย. 2024
- My check engine light came on and the code reader said code P0141. I then go through a diagnosis process and replace the oxygen sensor, which fixes the engine light issue and allowed me to pass smog testing.

Bank 1 sensor 2 heater circuit malfunction honda accord 2003 2004 2005 2006 2007 03 04 05 06 07 4 cylinders cylinder cyl four downstream oxygen sensor catalytic converter
I’m a Honda technician and have worked on them for 3 years now, but I generally work on newer Honda’s.
When I got asked to replace the downstream o2 sensor on a 03 accord, I looked up the instructions on sis (Honda’s online instruction manual basically) the instructions were useless. This video saved me a half hour of guessing where to be pulling trim/carpet and trying to figure out where the connector ended up!
Great resource, even for trained technicians.
Thank you for a meticulously recorded video. I went over it 3 or 4 times and mustered up the courage to order all the necessary parts and tools (pretty cheap off Amazon). Saw this video one last time and went in and replaced the downstream O2 sensor on my 05 Honda Accord LX. No more check engine light!
Good job! Glad it gave you the confidence to tackle the job. Thanks for the feedback!
Did you erase the check engine light or once the new sensor is plug the check engine light goes off automatically?? I just changed upstream and downstream sensor but light still on, I tried to erase the CEL, but it comes on again after 3 seconds... my sensors are muralist by the way🤔
?lo
A couple of more tips. Swap the clips over directly to the new sensor with the two laid out side by side and put them in the same locations before installing the new one.
Remove the four bolts that hold down the passenger front seat. You can then tip it forward completely and it will make it much easier, only takes a couple of minutes.
Rest is real good and you need the crows foot which you can rent.
Great tip on matching them up.
Very helpful video, thank you. Shop wanted $280 for this repair. Took me less than an hour with the right tools and part.
Great work!!
Thanks for the detailed video filled with all the tips and tricks! I just replaced my o2 downstream sensor tonight in my 2007 Accord. You saved me hours of frustration!
Awesome! Glad to hear it was helpful!!
Fantastic video!!! I would like to recommend to buy the 02 sensor from Honda because it gives the EXACTLY read to the car system, that way it will prevent other problems. 👍
FYI ... I found out today that accidentally leaving one of the hoses on the intake near the air filter disconnected after changing the air filter will throw the exact code for this bank1 sensor2 O2 sensor failure
my torque app said the light was on for 'o2 sensor slow to respond' ... instantly fixed by fixing the disconnected hose on the side of the intake tube
if you have this code for bank1 sensor 2, first check all of the hoses that attach to the intake before digging into this O2 sensor repair - especially if you've recently had the air filter out
if writing this helps at least one person it's worth it
Thank you. Had to do my dad's car & this video was invaluable. Ran into no surprises. Thx again.
Great! Thanks for the comment!
Thank you so much for this! It was well edited and all your information was concise and accurate. You saved me $300!
Thank you for the feedback! Glad it was helpful and you were able to save some $$$!
Video was a Huge help! Thank you 🙌🏼
Thank you!!
Perfect exactly what this amateur needed. Thank you sir ✊🔥🔥🔥🔥🔥🔥
Thank you! Ours had some sort of module under the seat directly over that plug which made it quite the PITA to get to but other than that, job was identical.
You're welcome! Glad it was helpful!
My 2007 EX-L has a module under the seat, too. It sits flush against the floor, so I'm not sure how to access the sensor plug. How did you do it?
@@prairiepanda I pulled back the carpet to expose the connector. The problem then was it is anchored to the floor making it impossible to reach. So, have to admit, I just ripped the anchor out of the floor. Its plastic and you can break it. Upon completion I just shoved the unanchored connecter back under the carpet and no one knows but me and you.
bunberrier , plus it’s an 07 so no one will meticulously look at it if you trade or sell it!
@@bunberrier I'm having this issue right now. It's definitely frustrating
Great video!!!!! My Bosh is different though, this will definitely help me a ton though!!! Thank you!!!
Great video...helped me here...all the way in Brazil
Feliz em te ajudar!

The best!
Awesome video. Thanks for posting!
Thanks for the comment!
Damn good video 👌🏽 track 🏃🏽♀️mom good to go now 💁🏽♀️ Hell with dealership.
the hell with dealership, i second that big time.
great video very help full a lot of information
I bought a Bosch O2 sensor at O-Rielly's and that was a big mistake, because it did not include the female plug, and if you do not follow the directions perfectly, it doesn't work, and that is what happened to me. The wire was too short, because the Bosch didn't provide enough cable on the sensor to reach the catalytic converter, (you had to cut and use the old cable, so they could save money, but I ended up getting screwed out of the $50 I spent and had to buy another one. Also doing research I found that Bosch often fails with Honda'a and you have replace the sensor again.
Man that sucks! Did you end up going with a Honda sensor or whatever brand it is they use? Thanks for the feedback
@@clintathusaz Denso
I'm a woman a real lady just watching in and you made this really easy looking to do
It is, with the proper tools and know-how. Some cars vary, like this one for instance, but with most cars you dont have to go inside of the cabin at all to change an O2 sensor. There are some cars that have them in difficult to reach places but they all have threads on one side and clips on the other so its just following the cable, remove it then reverse the process to install
So your doing the downstream one mine is on the other side left side drivers side and I got a new upstream one because I’m getting a code p420 and I paid 140$ for it for my 04 Honda accord ex sedan and the Cadillac converter got stolen they replaced it for 500$ but never changed the upstream one
Thank you for this video. Is this for v6 cars as well? I have a 3.2L VTEC engine automatic. Most powerful car I've ever owned, I love it! But the fuel cost! :)
Thanks Jack! Not sure how much of it crosses over to the V6 though...
great thorough video of how to check and replace, however, i have a 2004 Accord EX with heated seats and there is another electrical box under passenger seat!? do you know how to remove this?
Sorry not sure. Best of luck!
@@clintathusaz thanks.
so went to my mechanic and he said that the carpet is precut for this particular reason and that by working behind and infront of seat heater item you can get the carpet lose to expose the O2 sensor connection-which he showed me and did while i was there. if anyone has this problem you just have to work it getting the carpet open. Good luck.
Thx a lot it helped
thanks im startin now
Great vid thanks bro
Thanks for the comment!!
I don’t have an o2 sensor down there nor is there a hole for one, idk if there is the original piece down there on the exhaust
Mine had a black plastic cover under the pass seat that was difficult to remove before I could gain access to the connector. Did you forget to show that or did yours not have that?
I don't believe mine had that. Could be a difference in years or maybe my memory :)
It's a difference in the trim.
The EX trim comes with heated seats feature. So it would have the black box.
Clint's doesn't. It's probably not EX.
But they all use the same type of O2 sensors. Preferably Denso.
@@daviderhahon Gotcha, thanks for the distinction.
Thanks for the explanation David. Correct, mine was an LX with no heated seats
Anti-seize?
Good video 👍
I would like to ask if i can use other oxygen sensor to my unit because i couldn't find the P0140
Looking forward for your help
Blessings is there suppose to be power going to the connector that’s on the car?
hey does this work on a 6 cylinder too?
Sorry, I can't say because I never worked on one. Hopefully someone else with experience can answer.
Woww
that's a good tool
Nice video, just curious, is it possible to do this w/o having actual jack stands? Albeit, it seems easier.
I suppose if you're small enough to get in there and do the work then you could get away with not using them haha
I'm 6 2, so I have longer arms. I was able to do it without jack stands but struggled getting both arms in at the same time. Naturally this caused some difficulty but got it done.
@@clintathusaz Thanks for replying, I just ordered the scanner. I suspect I am getting the same code / issue.
It will be a huge pain for you if you cant jack up the passenger side of the car.
Is it necessary to replace the downstream sensor if it's not working? I'm driving my car for a year with a bad sensor. Is that bad or must I replace it?
It's not going to run as efficiently. And it won't pass emissions either
The car uses info from the O2 sensor to adjust fuel rich/leanness. If it's not working, your car may run extra rich which hurts your gas mileage (if your car runs lean it can damage the engine from overheating as the cylinders are igniting way too hot).
My 06 accord didn't look or work anything like you showed.
Great video - thanks! Btw, how many O2 sensors on the Accord V6? I’ve only found 2, correct?
Gene Penna should be 4 an upstream and downstream on each cat
Can u just remove the heat shield if you don't have the specialty tool?
Crimson Jax Autozone has the 3/4” socket
Sorry late reply, yes I have seen others do it that way
Got this code recently after going through a muddy puddle. (05 accord)
I cleaned the 4 tiny holes at rear of this O2 sensor, but code came back after some minutes.
Checking heater ohms, it reads about 8 ohms. Is this normal?
Can the check engine go off after just replacing the sensor?? I don't have the tool to reset the alarms
Rear sensor or front sensor?
I use the multimeter to measure resistance but nothing show up on multimeter, what is that mean?
So if ohms are good the sensor is good ??
How much was the sensor ? thanks. Great video
The one I bought was a bosche and it's $26 from Amazon right now. See link in the description. Thanks!
Thanks for getting back to me !!
I got one on ebay without the grommets rubber $14 free shipping take 2 weeks to deliver via Smart Post.
Could p0420 code be this problem too? I only asked cuz I got this same code and I replaced my CAT and I got this same code again
I didnt receive the black clip on the top, what should l do
When I go underneath my passenger seat I have a black box in the way. How do I remove this? I can't access without removing this it seems
Lmao. I had the same thing. I just took the bolts out of the seat and leaned it up. 14mm socket. Front left bolt on passenger seat is a bit annoying. Make sure you use a longer socket.
Can honda civic o2 sensor work?
This is bank 1 sensor 2 in v6 ?
Please what's the part number for the O² sensor(bosch)
13704
Autozone confirmed my engine light was because of my 02 sensor. Couple weeks later my car had trouble turning over. Headlights could turn on. AC, everything worked. I had to step on the gas in turn the ignition for it to start. Is that because of the 02 sensor or something else?
Something else
Did u ever get it fixed having this same problem
What is that pipe called that you took censor out of,,,I am trying to find one,,I need to replace my pipe that the censor fits in..people are calling it a catalytic converter and it is not!!! Thanks
That is a catalytic converter
@@garretbreckenfeld4993 yes it is,I was having an off day that day,,and sense that day,,I replaced the entire system,,,only to have the clutch give out at 234 thousand miles!!!
James Pelkey just had to replace my A/C clutch and coil in the Texas heat, no fun. 234,000 with original clutch is still
impressive, go Honda.
@@garretbreckenfeld4993 Thank you for sharing Garret ,please stay cool in the heat sir!
i have code p0420 on a 2007 honda accord 2.4. ive replaced the cat already with a direct fit and the light came back on the next day. Ive tested the rear 02 sensor with reads .3-.8 volts at idle. do you think i need to change the rear 02 sensor or what other things do you think could cause the p0420? thanks
I recently had my catalytic converter stolen. When the guy replaced it he stated it did not need an 02 sensor. My check engine light went on and sstayed on code p0141 came on. I noticed the catalytic converter he replaced was 2nd hand junk. But no place to put an 02 sensor.
What a shoddy repair guy! Sure your car will drive without the sensor but you can't pass emissions without it if that is something your state does.
That cat wasn't meant for that car.
Please stay away from that kind of repair guy.
how was it running before the new o2 sensor
I didn't notice anything wrong with how it ran, just the engine code
did the code disappeared? I am ready to change mine. I had one stripped nut and couldn’t take it off, I took the Honda to the muffler shop and cost me $30 to grind off the nut. I will replace the Cat tomorrow when I am off work. Also, I will replace the downstream sensor. Already have the item just can’t wait to play with it.
I hope the 420 code will comes off.
I got it done. I replaced the cat., oxygen sensor, and my 2005 accord lx runs great, engine code disappeared and I passed inspection. This was 4 months ago during summer.
huh? I thought b1s2 meant driver seat downstream. How could it be passenger seat lol
B1S1 is upstream off the exhaust manifold
What if my car is california emmisions and i dont live i heard its considerd california emissions and federsl compliant, everywhere says i need to get california emmssions o2 sensor your car must not be california emmissions compliant.
My light came on before getting it smog checked. After changing the sensor, clearing the codes,and driving it for a few hundred miles (car has to run internal tests) it passed CA smog no problem. The sensor in the description will get the job done. Best of luck!
My car is also California emmisions, the only difference is the price of the senor. California sensor was 160.00 and the regular on was 90.00.
I changed mine and the light is still on.
You'll have to drive it around for a bit for the computer to run all of its tests again. You MAY need to reset the code first, I can't remember off the top of my head. I think it was about 100 miles or so before the computer had performed all of its tests. It needs to be a mix of driving, city/highway. You can look up the procedure.
@@clintathusaz I had this fault come up on my car, but it disappeared the next day. I recently changed pump to Sheetz just before i got the engine light, i wonder if their substandard fuel is causing it.
You have to reset the check engine light, through either an OBDII device or by simply removing the negative terminal of your car battery for 30 seconds and putting it back (car looses all its memory, make sure you have your radio code etc.). If you did a good job with replacing the O2 sensor the check engine light should not come back, at least for that reason.
Tell him two minutes into it and bank 1 sensor 2 would be single exhaust Downstream and for 2 exhaust manifold or headers with two catalytic converters bank one would be driver side and bank 2 would be passenger side and sensor 1 and 3 is always Upstream while Sensor 2 and 4 are always Downstream...
You have circled in your thumbnail image for the video actually the wrong sensor you have sensor 1 Upstream Circle I hope that's not what you're about to replace because that would be a PO420 code 4 sensor 1 your sensor to should be Downstream after the cat meaning on the rear side of the cat sensor 1 is always ahead of the cat or ofcourse on the cat... hey I don't know which sense are you actually replace all I know is you have the wrong one Circled here up on your thumbnail so let's see what happens... okay so updating my comment you did the same thing everybody else does you just point to the one-year changing you don't differentiate anything else so in other words you're making it look like there's only one and it just confuses people and quite honestly when people are looking for other videos some of us know that it doesn't matter what car it is if it's the same kind of setup it'll be close to the same but I'm like okay if that's sensor 2 wear sensor 1 it would be nice if the hundreds of you that make these videos could differentiate stuff like that
Hello brother, how are you? Can you send me the oxygen sensor for the Honda Accord, the model of the two thousand and six, and the sensor key, twenty-two mm, is a gift from you. I am living in Western Sahara, south of Morocco.thank you
It's a Moroccan Sahara
