i got the code for oxygen sensor, i brought it a garage and they wanna charge me 400$ to replace it. wtf is that normal?

can't i just buy a replacement myself and install it myself and get someone to clear the code?
or is it more complicated for this accord?
i've changed o2 sensor on my old civics and no way it costed me 400$..

 

most of that $400 is labor for replacing it..yes u can buy it urself and replace it urself..just disconnect the battery after u replaced it to clear the code and drive it alot to set the monitors again

 

nice, i didn't know disconnecting battery will clear out the code.

thanks for the answer!

 

I would disconnect the cable now and see if the code goes away. If it returns then ok, change. By now they have many aftermarket O2 sensors. how many miles on the car?
check autopartswarehouse.com. Not sure how many O2 sensors there are. If there are 2, get a chilton manual to see how to test the resistance to see if they are bad.
get a portable torch from Home depot if it does not want to come out. It may need to be cleaned is all. I've seen that on older cars. Clean, alcohol spritz, air dry and good to go! if u buy a new one remember the anti-seize.

 

the car has 63,000km so around 37,000miles?

hmm, yea maybe i should just take it out and clean it first.
which alcohol do i use to clean it?

 

stepped away for a while. Uh regular rubbing as it evaporates quickly. With 37K miles and a honda I suggest unplugging the battery (neg) first then plugging her back on. if it's still on then clean it. I would suggest that electrical cleaner from teh auto parts store- I think that's it or map sensor cleaner. it evaporates welll also. let air dry. that's way too low mielage for that to happen and Honda makes quality parts. I've worked on many and owned 4

 

I'd take it to a honda dealer and see if they might be able to help you with that. since that's pretty low mileage it's worth a trip to the dealer to see if they might be able to do a goodwill repair for free.

 

I agree. 37k is low mileage. The dealer might help you out on it. Especially if you have any service history with them or any dealer for that matter.

 

I drive a 2004 I-4 accord and i recently had my 'check engine' lamp turn on too. I took my car to Autozone today and ran a diagnostics on my car.

Code P0141 (oxygen sensor - bank 1 sensor 2)

The dealship charges around $300-400 with parts, labor etc. and its a real rip off. The part costs $80 at autozone and i was told its really easy to replace yourself.

As far as your check engine light, here's the correct way to reset it.

1. With the Car Off, Press and hold down the Odometer Trip Reset Button. 2. While still pressing the Trip Reset Button, Turn the Ignition Key half way on where all your oil, check engine lights etc.. turn on. Don't turn it as far as you would to normally start the car. Wait a few seconds and the Check engine light will turn off. 3. Turn the key back to the Off position and you're done.


My problem is, my check engine light automatically turned off and i dunno if that means the problem is resolved. I read that driving with a bad O2 sensor means bad mileage and it could mess up the catalytic converter. I dunno whether to replace it or just keep driving. my mileage is on point, no problem.

 

Keep driving, if it comes back then consider replacing it.

 

thanks for the great tips guys. yea i'll reset it tonight and see if it comes back. and then i'll try to clean it before consider replacing it.

 

I think you can get a universal replacement online for like $30-$35 bucks, only thing is that you have to slice it to the wiring from the original O2 sensor. Not as hard as it sounds I did one for a Lexus (ya ya I know not a Honda but it's my other car) and it was eeeeeeeeasy since it came with the slice kit and full instructions. I had 2 O2 sensors out and after replacing them and resetting the ECU I had no codes for like 100 miles then I got a catalytic converter bad code. Turns out when you disconnect the battery it will reset the check engine light but then the ECU has to "relearn" all over again and it takes anywhere from 50-500 miles to run through all the system monitors for every vehicle including Hondas. I did all this in the same day since I was trying to pass emissions for my tag so I bought the "guaranteed to pass" emissions fuel system cleaner and reset the ECU again, filled up the tank and added the cleaner and cruised around all day. I stopped by several Autozones and had them all check the ECU even though there was no check engine light their scanner tool (if it's the right model...some Autozone's had it some didn't) has a diagnostic function to check "monitors" and can tell you if the car has or hasn't completed any of the "monitor" tests. If all of the monitors haven't been completed it means that there can still be something wrong with your car, the computer just hasn't decided if there is or not yet. This is why many people go into a shop to have something done to fix a check engine light and leave thinking that the problem was solved only to have the check engine light come on again soon after... the problem wasn't fixed but with the reset the ECU just needed time to decide. Lexus wanted $900 bucks to fix my 2 O2 sensors ($300 x 2 for sensors and $300 labor) and $1700 for a catalytic converter and I fixed it with 2 universal O2 sensors $70 ($35 x 2), $10 for the fuel cleaner, $40 worth of gas, $5 for an O2 socket 20 minutes install time and couple hours of just cruising around.
If you google the term "drive cycle" and your year and model of car you can probably find the actual requirements to complete each monitor checklist.

thats how you reset your Maintence Light actualy...need a scan tool for that lit up picture of an Engine that lights up orange. FYI the rear oxygen sensor is very common on these accords to fault...


For those dyi types. dont by aftermarket because itll burn out and Bosche usually dont even fix it since Hondas use Denso's, go to honda get the part $150 or so, cheepest o2 sensor honda uses in the fleet.. buy a good oxygen sensor removal tool or use a wrench, some anti sieze, scan tools are cheep at Napa so buy one for yourself if you wanna start working on cars! $150 bucks I got mine off my Snap-on guy, but Napa sells em too for a bit more or less depending on your needs.

How to Replaced p0141 rear o2 sensor:
push the p/s front seat all the way forward, pull back the pre cut carpet slightly, disconnect the grey connector coming through the floor from under the vehicle,( wiring with a black rubber gromet), lift it (put the car up on a jack stand on the p/s with thefloor jack still supporting), follow the wire to the cat where the o2 sensor is located and start removing the wiring from the heat shield. once done, hit the o2 sensor with some PB blaseter or heat at the base where the thred are, let it sit for a few mins if with PB blaster and then remove it. Once removed, anti seize the new threds on the new 02 sensor and install, re-secure the wireing to the heatshield, route the connector back up through the floor, connect, push seat back, hook up scan tool, and clear.then drive it and see if it stays out.

Wow that is really expensive. I changed mine at 72k for 150.

 

I just picked up a bosch sensor from Advance for $65 due to engine light with a bank 1 sensor 2 code. Wasn't sure how to get to the connector which is how I found this website. I replied to another post asking where the connector is and now I see. Should I return the bosch before installing it???? Sounds like I might be wasting time?

 

There should be an 80,000 mile warranty on your Oxygen Sensor and Catalytic converter. Call Honda and see if they'll change it for free.

 

At 145,000 miles I think all warranty has expired. With my new knowledge of peeling the carpet back under the passenger seat, I went ahead and installed the bosch sensor. It was very easy. The check engine light went off all by itself about 30 mins into my hour drive that I had after the install. I'm happy. The new sensor had all the zip ties and new boot/grommet already in place. It has a 1 year warranty with it so we'll see how long it works.

 

I replaced mine O2 sensor(the one on the cat) at around 80K because the CEL came on, go to O'Reileys/Autozone. I think I bought it at Autozone for like 70 bucks, was very easy to replace. I sold to car at almost 130K miles and no CEL, don't pay for labor especially it should only take you about 15-30 mins with waiting on WD40.

 

Goodwill repair on a 2003? Good luck with that (at my dealer, anyway).
