Infiniti JX35 QX60 O2 sensors P0037 P0420

[@davidwalker4113]

You CAN get to the Bank 1 sensor 2 without going through the wheel well. But it's a tight fit with a rachet and the oxygen sensor attachment -- no room for a breaker bar. You have to reach up over the exhaust pipe toward the wheel, and you can barely fit a rachet in there -- you'll have to get under the vehicle and locate it yourself. I was able to use a pry bar against the engine block, prying the rachet handle away from the engine block, enough to break the bolt loose. Busted my knuckle up when it happened, but at least I got it done! (pre-soaked several times with PB Blaster)

Having this issue on my 2013 JX35 and was quoted 2100$ to fix. Thanks for this video

[@lifewithsouljab8092]

The only hardest 02 sensor to reach behind the intake

[@felipeborrero1489]

Just went to auto care USA, they quoted me 104 dollars to replace the oxygen sensor

[@dominickvennari9400]

I have a QX56. O2 sensors for bank 1 upstream and downstream are $380. Not to mention nothing is easily accessible unfortunately in the engine bay. Trying to find solutions but think it’s going to come down to a mechanic

[@bhosterman]

I’m in the same boat. Haven’t got the specifics yet but the dealer told me roughly the same thing… less than 24 hours after purchase. They cleared the code and it stayed off for about 10 miles. I’m guessing that’s what they did after each test drive to avoid fixing it and I’m the sucker stuck with it now.

[@radius8283]

My god I have a 2005 4runner daily driver and used it for work for 10 years and have never replaced any or this sensors. Heck I’ve replaced the spark plugs because it’s way overdue at 250K miles. Mileage now is 300k and this truck is still running.

Why would you be looking at a car repair video if your vehicle is so reliable? 🧢

[@rad2304]

@@brianb4501because wife wants to buy one and I’m doing my due diligence. That’s the essence of KZbin and Google. Before buying we can find out the pros and cons of a particular product so we avoid buyers remorse. Ain’t it fun?

[@marito310]

Great info Very specific and easy to understand, thank you.

[@nathanielblair2397]

Can you show how it’s supposed to be after you fixed it with tape and everything? Seem like a common issue for these types of vehicles ours is new and already having O2 sensor problems.

[@AlexPerea1]

Hi can you please share where bank 1 sensor 1 is?

[@Denttransformations]

Thanks for the info!! Haven’t been able to find this anywhere else.

[@eagle___empire3175]

@Tuckers' Workshop Where is Bank 1 Sensor 1?

[@jasonfromm5637]

Think u can tell me where bank one sensor 1 is? Ty

[@burntfreckle7996]

Such great video!

[@thereelchris116]

Helpful video, I’m having a similar issue with my JX

[@DebrahBond]

X just wanted to know how many catlackconverter is

[@GizmoMalshi]

You didn't show where your disconnected wire was? With the image zoomed in I can't see if it's under the car, in the wheel well or from under the hood.

[@tuckersworkshop]

I was under the car looking up into the wheel well. If you trace the wire from the O2 sensor it goes up and then towards the wheel angled to the rear of the wheel well. Good luck.

[@ScottLaForce-op1wq]

My 2020 QX60 bank 2 sensor 2 is not matching the ones from the auto parts store, where can I find one?

[@tuckersworkshop]

Try Rock Auto

[@marito310]

can I ask, was your car emitting(puffing) smoke randomly during acceleration? thanks

[@tuckersworkshop]

No smoke. Car was running like normal

[@notyourbiz2343]

Hey there, can you please tell me how many O2 sensors this vehicle has ? 2 or 4?

[@TommyConstant-ku2zo]

4

[@brucelee5465]

I only have p0420 on my jx35. I can hear noise coming from exhaust near engine. should I change catalytic converter to fix this problem?

[@tuckersworkshop]

It might. If you’re looking to replace the bank 1 cat, you can pick it up for $179 at mufflers express.

[@tedheefner4946]

Good job Jeff!

Part number for o2 sensor bank 2

[@mooauto2388]

Hello you still have the car ?

[@Moretz940]

Thanks for the info.

[@hamzababli678]

Is it safe to drive the car with this problem?

[@Mr.CBriggs]

Where are u located

[@kidritalin1]

Thank you

[@wuxianku]

Quick question Infiniti jx35 p0420 code is upstream o2sensor or downstream o2 sensor problem ?

[@sugarcreekfarm1]

P0420 just indicates the catalytic converter which could be related to an O2 sensor. Bank 1 or 2 indicates the side of the engine. Sensor 1 is upstream, sensor 2 is down stream.

[@gibson7654]

@@sugarcreekfarm1 that doesn't answer his question. Which one of these would likely throw the P0420 code?

[@tonyblair7226]

@@gibson7654 the issue could be from a bad 02 sensor or potentially the cat itself. Its typical to start at the most economical first (02 sensors)and work your way to the more expensive fix (the CAT).

[@Miracles895]

You gotta clean this engine bro

[@gilbertnunez732]

That's not the fix.
