The sensor is an electrical component. Do not soak it in gasoline - that will damage it. Soak it in alcohol. Be sure and let it thoroughly dry out. The very dainty little heater element (coil) may have had gasoline still in proximity and ignited it which then blew the heater element. Note alcohol will do the same so you need to let it dry and evaporate off.
Thank you for this video. My 2006 Honda Pilot got P0137 code which indicated bank 1 sensor 2. I believe this sensor should be located under the bottom of the car, is this correct? I think your video also showed that location too right?
Bank one is the one that is closest to the firewall, and sensor 2 is the lower one so yes under the car. But I was working on bank 2 in the video is the bank closest to the bumper
Did you try cleaning the Cat converter first, before installing the 02 Sensor? Just wondering, thanks, great video and great narration/explaining. You should do voice-overs. Liked & subscribed!
Car parts are way more expensive in Canada. I usually order my parts through the USA from rockauto. Even with shipping, exchange rate and import fees the parts can be half the price.
It is the underside of the vehicle, but I never had a plastic cover in that area. The plastic piece is a bit further forward. But I am looking straight up from the floor in that shot.
@@DIYNorth Thanks. Yeah, it used to have full plastic spoiler up there. Both portions in front of the front wheels have disappeared into the environment.
@@ccscomments757 I got mine second hand, and I think it was maybe a fleet vehicle since it had some trim options that were so low that they were never offered to the public. As a result I'm never sure if my vehicle was in the correct configuration or if I was actually missing something that was there when it was new.
No i don't think so. I think it's just one clip on the top, but they could be pretty siezed together with dust and stuff. Once it comes off once its much easier.
is it worse than 15 MPG city, 20 MPG highway? in L/100km it would be 16 L/100km city and 12 L/100km highway. If that is what you are achieving then it is about right for that vehicle.
My 07' pilot gets the P0420 code here (bank 1) and there. I used Cataclean a few times, sometimes it clears it, sometimes it doesn't. My mechanic said it does work to help clean it and also to use premium gas / good detergent gas. Right now my issue isn't so much emmisions (In FL where they don't have it) but I am loosing almost 100-150 Miles per my tank , the MPG is like a Hummer right now and I am just running through gas like it's water. What can I do to solve this?
If I were in Florida I would just go surfing and forget about my Honda. But...Here are the recommendations of what might be causing excessive fuel consumption. 1) Dirty or clogged air filter element 2) Emission system not functioning properly 3) Fuel Injector system malfunction (or spark Plugs) 4) Low tire pressure/incorrect size. (also fuel leak). You might need to get the diagnostic done on the Emissions system if everything else is fine.
@@DIYNorth Not many waves here ... although I know people who surf, but definitely not like the west coast waves (and the water is alot warmer!) 1) Air Filter is Clean - I replaced it recently and do so annually 2) Emmisions not functioning properly - quite possible, since the P0420 is an emmissions issues 3) Fuel Injector Malfunction - I'll have to check into that, the car doesn't ride rough or idle rough or anything though, feels the same as normal 4) Low TP - I check it and keep it at 32psi.
Maybe, it's hard to say because that vehicle had so many bad sensors, vacuum leaks etc. Its not a great test subject. I noticed a gradual decrease in fuel efficiency, but not some noteworthy crazy drop. It was always fairly efficient
If you cant go more than 20mph you should try running that chemical down through the engine via a vacuum hose going into the throttle body or putting the chemical in an indication service tank and let that feed the chemical through the engines throttle body.
Very good video, i have a 09 mdx with a p0430 code i replace the bank 2 sensor 1. And code still on. I think i need to replace sensor 2. Did The new sensor fix your problem? Thanks for the information
Good luck. I found that once my Pilot started throwing codes it started throwing new ones every time I fixed one. Became an endless fight to keep the check engine light off.
No, the O2 sensor didn't have a significant impact on it in my case. The coolant temperature sensor had a more noticeable impact when it went out. There may be a range of problems that the O2 sensor code could come up for though.
The manual I have says that P0420 is "Catalyst system efficiency below threshold" (specific to the rear cylinder head) while P0430 is for the front cylinder head. I assume you have a Honda 6 cylinder of some type. It might not be the catalytic converter itself, but rather a bad O2 sensor; although it could be a bad catalytic converter as well.
@@ram43x80 Sorry, didn't see the comment. Sometimes youtube gives an alert, other times not. Did this on front converted, and downstream sensor....But I think you know that now.
For anything powertrain related it should all be the same since the Pilot didn't come with multiple engine types in 2005. Electrical may be a bit different if the leather version came with DVD players or had some other features that the base model didn't come with. Some Pilots came in front wheel drive only versions starting in 2006 and those actually do have a variation of the J35 engine that is slightly different from the AWD equivalent. So, that is a bit of a long answer to say that there are some differences, but they are all mostly the same.
I'm looking at pictures of the manifold catalytic converters and noticing _each_ has two O2 sensors, for a total of 4. At least on my 2006 Pilot 4WD. So if the P0420 code is complaining about weak cat performance, how would someone know which of the two sensors attached to the cat nearest the firewall is bad (or if it's the converter instead?
420 is rear cylinder 430 is front. Then there is a bunch of codes for up stream and downstream to determine which o2 sensor it is If you have to guess I would try the downstream sensor first because it is a lot cheaper than the upstream. But that's only if you need to take a guess, for example if all you know is the cat is below efficiency and just want to try a cheap test with an o2 sensor change.
@@DIYNorth Thanks. Would any of the testers point me to the upstream sensor, or does the vehicle only compare both upstream and downstream and report an overall problem, never knowing which of the two on that side is bad (assuming it's not the converter of course.)
Sorry, disregard my comment. I now realize P0420 doesn't say anything about any of the Bank 1 oxygen sensors. It sounds more like a catalytic converter that's gone bad.
@@thenexthobby Yes, it is generic code for the catalytic converter below efficiency. When I was looking at used Pilots about a year ago I noticed that a lot of them with 200k and over miles were being sold with a 0420 or 0430 code. Those upper Cats are extremely expensive at dealerships in Canada. I think about $1000 each just for one of the Cats.
@@DIYNorth You know, another YT channel claimed that only Honda cats are any good. Our '06 only has 88,000 miles, so I'm thinking the OEM cats aren't great themselves. rockauto.com has several for quite a bit less than the dealer. I'm getting closer to just replacing the cat in the rear because I really don't see how P0420 can point to anything but that.
How is this a good video.. he didn’t even show that the problem left.. he gave a update on the bull crap he put in the gas tanks. But not the actual thing smh
The video is title "Oxygen Sensor Replacement", to watch the oxygen sensor replacement please go to 4:23 as indicated at the 14 second point in the video. Bull Crap is far to thick to put in the gas tank I would never recommend you do that, what I used was Dura Lube, which incidentally I also don't recommend.
good camera work! And your calm voice is invaluable to someone about to throw things!
Thanks for watching and for the feedback
Una pregunta amigo, los sensores son los mismos modelos ?
Osea al banco 1 y al banco 2 les queda el mismo sensor ? @@DIYNorth
@@dannblancas665 Lo siento, pero no estoy seguro si son intercambiables o no.

No, their wasnt any other work done
My bank 2 sensor 2 I took out of a 2016 Honda Pilot was an ngk OEM. I replaced it with the same exact part and it was only $62 USD.
Car parts are way more expensive in Canada. I usually order my parts through the USA from rockauto. Even with shipping, exchange rate and import fees the parts can be half the price.
to be clear, at 2:00 into the video, we are looking at the underside of the car with the plastic air deflector removed, correct?
It is the underside of the vehicle, but I never had a plastic cover in that area. The plastic piece is a bit further forward. But I am looking straight up from the floor in that shot.
@@DIYNorth Thanks. Yeah, it used to have full plastic spoiler up there. Both portions in front of the front wheels have disappeared into the environment.
and oddly, there is a tiny (like 4x5) opening that I can look up and see that 02 sensor.

Thanks that question was driving me nuts
Glad it was of benefit to you.
How did you get the electric connector off. Is there two latches?
No i don't think so. I think it's just one clip on the top, but they could be pretty siezed together with dust and stuff. Once it comes off once its much easier.

Yes, 100%, the new sensor ended my code problem. I have another code in the other catalytic converter, but that is a separate problem.
@@DIYNorth thanks, i will replace the new secondary sensor hope it fix my problem.
Hoping my 06 is the same. I'm getting cylinder codes and it's going in and out.
Good luck. I found that once my Pilot started throwing codes it started throwing new ones every time I fixed one. Became an endless fight to keep the check engine light off.
thx!!
No problem
Thanks for watching
Did ur pilot go into limpmode w the o2 sensor problem?
No, the O2 sensor didn't have a significant impact on it in my case. The coolant temperature sensor had a more noticeable impact when it went out. There may be a range of problems that the O2 sensor code could come up for though.
Blessings can you tell me what bank is that 02 sensor is on
Bank 2. The one closest to the bumper.
Bank 1, which is closer to the fire wall is a bit tougher to get at
@@DIYNorth does that p0430 code come up for both of them?
@@OleManGaming no p420 is for the rear cylinder head
@@DIYNorth thank you
I have just a P0420 code, what could it be?

I assume you have a Honda 6 cylinder of some type. It might not be the catalytic converter itself, but rather a bad O2 sensor; although it could be a bad catalytic converter as well.
There r 2 catalytic converters on the 05 pilot, did u remove both sensors?
And it looks like there r 2 sensors on 1 converter?
I got it my bad, u made it clear what side, sorry 😞
@@ram43x80 Sorry, didn't see the comment. Sometimes youtube gives an alert, other times not. Did this on front converted, and downstream sensor....But I think you know that now.
If my engine is a 3.5L what difference does it make if the Pilot is EX, EX-L or whatever? Someone please answer my question!
For anything powertrain related it should all be the same since the Pilot didn't come with multiple engine types in 2005.

Is that bank 1 s 2?
