Great video I was able to fix my 03 accord. You don't need to take the seat out. Just move the passenger seat all the way forward. Then reach for the flap to access the harness
Thank you so much! It only cost me $55 to fix compared to $250-$300. Your video showed exactly what to do. I just wish mine came out as easy as yours did. My O2 is original and has over 266,000 miles on it and was rusted completely in place. Thanks again for the help.
Hey Robert your video was great man. I am not a mechanic by any stretch of the imagination but I know a lot about cars. My daughter has a 2005 Honda accord LX 2 door coupe and hers just popped up the notorious P0139 02 oxygen sensor. I won't be able to do this job but I am going to take the car to my mechanic but I still learned alot of info so at least I know what the mechanic will be doing so thanks again Robert. My daughter's car has about 146,000 miles we just got it about 5 month's ago. The car had 142k when we bought it. It has been driving fine with no issues still drives good with the check engine light on which just came on yesterday 7/20/18. I see this info was uploaded 2 yrs ago 2016 thanks again man ✌️🏾
Great video. Figured I would return to leave a comment. Bought a 2005 CR-V from an an auto auction. Had it for a week when the P0139 code popped up. My issue ended up being from a critter chewing the wires at the connection under the seat. I'm sure the dealership would have kept the car for 2 weeks and charged $3k for a complete wiring harness install from bumper to bumper. $42 part to replace the sensor/wire and 20 minutes of super easy labor. Specialty socket was $6. Good to have in the toolbox! Code cleared itself and hasn't returned in 2 months. And, no.. I certainly did not torque my seat bolts properly to complete the job. Godzilla gorilla mode fully engaged. No squeaks or rattles allowed in the vehicle. Haaa. :)
Great video & instructions. I too did not have to remove the seat - just pushed it all the way forward. Replaced my 02 sensor on my 2005 Honda Accord. Thank you.
Thanks for the great video. My code popped up first real day of winter here - snow on ground. A buddy has a code reader and cleared it. It hasn't thrown an error since but I at least know what is involved.
Really helpful thankyou! My wife's 05 Civic has the P0139 code but I read that it uses a newer "wide band" 02 sensor. Do you recall if this was a wide band replacement?
Nice job Robert. As others have said and you already know, the seat doesn't need to be taken out. But removing the 4 bolts is still a good idea, so you can angle up the backside of the seat to get to the connector easier. Do you still have this Accord? I'm finally selling my 2005 with 280,000 miles and getting a 2010 with 55,000 miles.
that must be a common problem with the 05 accords because I just got that code, now I'm mad it's under the car because it won't be a repair I can do myself. Also did replacing the sensor fix the problem? I'm worried I'll replace the sensor and then have to deal with needing a new cat. How much do you think this would cost at the honda dealership?
This code comes because the ECU detected a high fuel level in the case of decceleration. The cause is mostly related to the fuel cap and the canester filter.
Hopefully you see this who commented before. I had replaced both O2 sensors new Denso and this light came on after about 10,000 miles/3 months on the rear sensor. (I drive a lot). What fixes this besides resetting the CE light. What about the fuel injector cleaner liquid you can put in your gas tank? A tighter gas cap? Is it just a random code that I can reset if the sensors are pretty new?
I got the cat changed last year for catalytic converter P0420 error on my 2016 CRV. 6 months down the line I got the P0139 error. I changed the downstream sensor this time. 2000 miles more I again got the same P0139 error. I called Denso and they sent me a new sensor because of warranty. I called the mechanic to reinstall the downstream sensor and he says P0139 error may be because of upstream sensor also and recommending to replace upstream sensor. I am so confused this is driving me nuts!!!!!!
@@RobertDIY I put top tier from Costco. I bought this at 121000 miles used but the single owner had excellent carfax with all service and regular maintenance records from dealership.
Do you know if you get a p0420 coed reading it might also be the same. They said it was my cat converter but the car runs fine will idle a lot of bit but runs ok. I dont think my cat converter needs replacing.
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 re-attaching 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
I have a 2004 accord with electric seats, when I power the seat forward. It tilts to the right and moves forward only a little bit. Could you tell me what I can do it fix this. You've already showed me about the o2 I will be installing this weekend
@@RobertDIY Thank you Robert for your reply. So I have to replace both the one for the front and back (up and downstream at the same time)? code P0139 and P0141 are not the same sensor then?
Man, that was a bunch of crap! I'm kidding... Thanks for the video. Makes me wonder why the connector has to be inside the car? I could just go 2 feet forward into the engine bay into a plastic box where all the other junk is so you wouldn't have to pull the seat, carpet, plug and oil everything up. But I guess if you were to take this to Honda, they can charge you around 3 hours to take your car apart and put it back together again for a $45 part...
Code p0139 and the store gave me this item number Denso item 234-4797 does this sound correct guys for the sensor on this video and good video thank you.
great video. why garagist always trying to rip us apart. they are working in the dirt but are trying to be rich like doctor. someone asksd me 80$ for the part and 150 for the work. so he double the price of the part this shit dont take more then 30min to 45.
Robert DIY yeah an evap code, forget number offhand, I deleted them like 65-70 miles ago, so far so good, changed my high pressure power steering line & pressure sensor, but that shouldn’t have affected it

This man is epic he did everything with one hand lol. Great video sir really helped out !
Thanks for watching.
@@RobertDIY I'm not a mechanic. Is that the Downstream or upstream sensor ? What's the difference between the sensors?
@@luisasantiago4260 Downstream
Ok 👌
Thank you Robert, this is exactly what I need. You're the only one who talks about removing the seat.
thanks for watching.
Awesome video. This is what a proper video is. Will be attempting to follow along and replace on my 05 Honda Accord Coupe. Thanks

Great vid, helped me understand much better. I'll be attempting this on an 06 accord in the morning.
+Antoine Tinker cool.
This is great information. Thank you so much! And I love your Pittsburgh Steelers hat too!!
Woot woot!
Thanks robert. My cat got stolen and this video helped show how to install tge new o2
Ouch
Great information explains very well I'm going to post again when I'm finished to rate this
Thanks
Got the same wonderful car. 277k on the clock. Still runs like a dream.
awesome
Great job documenting the process Robert DIY.
Thanks 👍
looks pretty simple, thank you! now to find a sensor remove/install tool, good thing i work at advance auto!
Nice.
Thanks for making this video it was extremely helpful and informative. It definitely made the job super quick and easy.
Glad it helped!
Awesome. Great video. You saved me 200.00 Thank you!
You are welcome.
If you change the 02 sensor at catalytic converter the upstream needs to replaced as well
OK
Great video. GO STEELERS!!

Yes, I had that code. Stayed around until I replaced my cat. My car ran fine for about 3 years.
i have a honda civic si coupe 2006 is it possible that the sensor switch under the seat as well?
😂 Let me check my CZcams Mechanic crystal ball...
@@RobertDIY alright
Is it possible to "clean" the sensor and restore its opration or does this code mean that the sensor is done and needs to be replaced?
Possible...yes.
Hi Robort,
What car ramps that you used and would you recommend that brand and model? Thank you.
Rihno ramps.
Hi will this be the same on a 08 civic 1.8 ? It has the same code
Sad to say, I do not know.
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

thanks for sharing.
I got the P0139 code too what 02 sensor should I get 07 honda accord
I guess the one I did here.
You seem like a cool guy
Thanks for watching.
I have a 2004 accord with electric seats, when I power the seat forward. It tilts to the right and moves forward only a little bit. Could you tell me what I can do it fix this. You've already showed me about the o2 I will be installing this weekend
Sad to say, I've never dealt with it.
Is the po1157 the same as this sensor ?
I have no idea.
Does this process apply to a Jeep Cherokee ?
I have no idea
What size is the o2 sensor socket?
I don't remember. The o2 socket tool is one size fits all. Maybe something like 1-1/4".
Hopefully once the code was reset the engine management computer was happy again :-D.
What an odd place to connect a sensor to :-/
Yes I was surprised.
Do you really need to remove the front seats?
Did you watch the video?
What did the fuel trims look like?
I don't know, that's above my pay grade.
thanks. just replaced mines passed emissions
Sweet, thanks for watching.
I have a honda CRV which reading this code p0139. The car does not start after it is used for some time
DANG
Did you get it diagnosed? How did you go about it?
if the scanner shows P0139 and P0141, does it mean the same 02 sensor Robert?
One will cause both issues. The front sensor is most import, I'd replace that one and then the rear (down stream) one if you still have a code.
@@RobertDIY Thank you Robert for your reply. So I have to replace both the one for the front and back (up and downstream at the same time)? code P0139 and P0141 are not the same sensor then?
Huh? The front sensor is most import, I'd replace that one.
Is this video for 07 honda accord too
+lyndae bowers Maybe, please check the comments.
My cAr sensor have a problem p1157 is taking more gas
Ouch
Whats part number of that new lambda sensor?
+Piotr Jankowski did you watch the video or read the comments?
Robert DIY yes i did but denso parts number starts DOX-... and numbers. I cant find on denso catalogue
+Piotr Jankowski I believe I mentioned getting it from Rock Auto.
I replaced the sensor and still throws the same code.
ok, maybe the cat is bad. Where did you get the sensor?
Same. 2005 Accord 2.4L. P0139 code pops up intermittently. Used the same sensor.
Anyone have the actual part number for the sensor???
Did you check the description area?

was that a v6
+Honda ghost 1989 no, I 4.
Mines has 2 codes PO139 PO420

yes it would
Is it an Upstream or Downstream O2 sensor?
What did the video say?
Code p0139 and the store gave me this item number Denso item 234-4797 does this sound correct guys for the sensor on this video and good video thank you.

Why is it under the car, what a shit design
Because they didn't want to run the hot exhaust pipe through the inside of the car.
