I appreciate the requests for more videos and information, but I’m just a
regular guy that tries to fix the easier things myself. I couldn’t find a
video on how to do this back when I did it, so I just posted one to help
other people out after I did it. Sorry I can’t more, but I’m not a
mechanic.
There are 2 sensors. The code should be specific to which one is bad but
it’s been so long since I did this I really don’t remember the details. But
there are definitely 2.
Are there two seperate 02 sensors? An upstream and downstream?
What mileage point does Honda recommend to replace o2 sensor?
One u complete work remove ground wire of battery a min to reset system n
get rid engine light
It was easy but had removed all bolt s of passenger seat with 1/2 socket
the old senor came out easily for 2005 honda accord coupe
Can you do a You Tube on the 2005 Honda Accord Front O2 sensor replacement?
Is this the same as an LAF sensor?
thanks so much Chris, this was a major help. I had the P1041 code on my
wife’s 2005 accord. Bought the Denso sensor for $44 on amazon and decided
to do it myself after viewing your video. Took me an hour and was actually
a lot easier than I expected. Saved a few hundred bucks as the Honda
dealership wanted $350. Thanks again.
To Others:
This was a BIG help for my ’05 4 cyl Accord as well.
You also should remove the lower catalytic converter shroud. [(4) 10mm cap
screws]. This helps gain access to the sensor.
To gain access to the connector, you need to move the front passenger seat
all the way forward. Then remove the (2) 10mm nuts on the seat track (one
on each side), of a metal bracket which holds a plastic shroud. Maneuver
the bracket and shroud to gain access to the actual connector. With the
tip of a flat screwdriver, push on the side of the release tab, while
pulling the sensor wires.
After installation, you will need to clear/reset the “computer” wity either
a code reader, or disconnecting the battery for a minute or two. (Have
your radio code handy to reset your radio).
I chance the 02 and 01 sensor and the check engine light is still on.
helpful vid. just done this myself. new sensor was about $74 bucks at
advance auto parts. would be much easier with a sensor socket but I removed
the catalytic heat shield like in the vid.

Thanks for your video its works for my accord. can u upload the video how
to service a pump brake of accord?
@mohdtmn Glad it helps! If you could post a video of the other one and post
a link to it from a comment here, then everyone will know how to do both.
And good luck on the other. It should be just as easy.
thanks for posting this!
You mean the one hanging off the exhaust pipe? Yeah, that’s gonna be the
fuel mix.
My 95 Accord failed low speed idle emissions three times, After first
failure, changed plugs, failed again, added RXP, failed again. Took to
Honda dealer, he said replace distributor 1029 p+l, and replace 02 sensor,
531 p+l. Passed hi speed emissions test each time. Your thoughts about this
diagnosis curing my problem?
Thank you, I am about to change the two oxygen sensors of my 03 accord and
you showed me how to do one of them 🙂
Need disconect batery?
Done with my 2005 Honda Acoord LX, differences with video. To remove the
black shroud under the seat, go in from the front and wedge the 2 clips
off, slowly prying them off. Between the top part of the separator and the
shroud, not directly on the claw things holding it down. The carpet is
buttoned in way up, so you have to remove the seat. Just 4 bolts holding
the seat down, so it’s an easy removal. Once seat is removed, you have lots
of room to work with. And use the rental 02 wrench!
$72 Denso O2 sensor at Autozone :p 2005 Accord. I’m going to have to get
the 02 Socket wrench set since I couldn’t get my heat shield off 🙁
Thanks for posting this! I’ll definitely be going this route instead of
throwing more money at the mechanic.
I finally got it sorted. I spoke with a mechanic and he said I needed to
use the OEM part. I was using a Bosch sensor before and have since replaced
it with a Denso sensor. It’s been a few weeks and no light!
codes said my 03 EX was misfiring on #2. I replaced all spark plugs and it
still misfires :-/
I am so going to help my uncle put this part on my car VS paying the
dealership a shit load of money!!! Thank you so much!! I am going to do
something for myself with the money I am saving!!!
Thanks for posting this. I have to replace the rear o2 sensor in my ’03
Accord Coupe this weekend and it’s really handy to be able to see what I’ll
need to get the job done.
Many thanks..had trouble finding the plug under the seat. 🙂
VERY HELPFUL. I own a 2004 Accord EX 4 Door. 1. If you get the sensor from
AutoZone, you can rent a special tool for free (I paid a $25 deposit) so
you don’t have to take off the converter shield. 2. Push the front
passenger back and unhook the carpet from the round clip. 3. Push same seat
all the way forward and unscrew that little box set-up (see video). Now you
can pull the carpet back. 4. When your done following the video, disconnect
battery (wait), reconnect battery and your done.
So is this the O2 sensor for the cabin filter or the one for the fuel mix?
Thank you for the post, it helped a ton! Did your check engine light come
on again after you replaced this? I replaced mine the other day after my
CEL came on and popped the P0139 code. I unplugged the battery so the light
was out for a few days while the readiness codes were being set. The light
came back on with the same code yesterday. I’m wondering if anybody has had
the same issue.
@genemerkin My light didn’t come back on, but I did have to wait a full
week for the computer to reset so I could pass emissions.
Thanks for the video. Opening the bottom exhaust cover and remove the
passenger seat was very helpful as well. The check engine light went off
after 5 mins
Thanks for posting this .. saved me a lot of money .. did it myself. I have
a 2004 Honda and I would recommend unbolting the front passenger seat and
move it back to make it a lot easier to get at the wiring / connection
beneath the seat. Only 4 bolts to move the seat out of the way.
No problem, anything to stick it up at outrageous repair costs. I got a
quote for $400 to do this 15 minute repair at the dealership.
Thanks, MtnMaiden. I unbolted the seat and leaned it back to remove the
carpet and access the connector and grommet. Much easier. Thanks for a
great tip!
