How to replace primary(upstream) oxygen sensor on V6 Honda Accord and Acura 1998-2002 (J Series DIY) 

Only video that shows the V6. Thank you.

Very important for me to know what I should expect to see and where. This video is well lit and very clear. Thanks.

Excellent video! Just did this following this video. Had a engine light on with Code PO132 (upstream O2 sensor). Bought the exact sensor from Advanced Auto for about $81. I rented the same Oxygen sensor socket set for $42. Used a breaker to loosen the sensor, was able to separate the old sensor with one hand while under the car. Did the entire job under the car. Thanks for the post!

Great video. Thank you sir.

Igor - great video! When you removed the wiring harness with 2 hands by going through the hood I was able to do that successfully but the other half of the wire, which is actually the o2 sensor, is connected to a piece of metal in a very tight space. If I pull too hard the metal clip will break and detach from the car, mostly because it’s rusted. Your wire seems to be hanging free. Any suggestions on how to remove the o2 sensor from the metal clip? [2002 Honda Accord EX V6]

Igor, this looks like the downstream o2 sensor. Are you sure you are showing us the upstream sensor? I thought the upstream sensor is in front of the radiator? Thanks!

Nice video 22mm works sometime spray it down

Nice informative video

Thank you for the post. Was the sensor you changed the primary or the secondary and what type of connections, male/female they have?

Mine is so stripped one way but not the other even using torch did nothing . Going to try a 22 wrench 🔧 instead of the O2 sensor sockets

Pb blaster would help loosen it off its threads. Also invest in some jackstands its better to be safe then sorry. 😉 Great tutorial vid. 👍

This is the bank 1 sensor right?

@Igor Kadulenkov PB Blaster is your friend.

Is that to fix the P0420 code?

next time let get really hot drive into it is super come off easyer

it upstream downstream is on the cat

is the 02 sens for bank one?

Where is the downstream 02 senor

why take off the wheels?

😭that foot @1:13

should have sprayed pb blasted or at least wd40 and used a half in. drive ratchet w/ 3/8 adapter, comes right out...

That's definitely the dwnstream o2

use a braker bar

Yeah, instead of buying a $200 oxy sensor you could have just cleaned it with some carb cleaner. Don't get angry with me Igor.

Is there a second sensor? My bank 1 shot 2 is showing up on the conputer.
