P0051- oxygen sensor bank 2 sensor 1 for RX 350 SOLVED
 

For the above problem i have solved the problem with the assistance of this link :- https://www.drive2.ru/l/5984986/

Thank you.

Thanks for letting us know and sharing the solution.

Does anyone know the part number for Denso o2 sensor that is in bank 2 sensor 2.
Downstream front or after cat.
I can't figure it out. Car was built in North America, Canada and has Ca emissions.
I thought I narrowed it down to 234-4416 or DEN 234-4400. Napa says first looks like 234-4400 is generic Rx 350 and 450.
Now the guy at parts not says 234-4509?
It's a 2011 Rx 350, again made in Canada with California emmisions. The old cord is 10in which tells me 234-4416 is closest but can I go off the length of the wire?
All the info on the web gives me a different answer.
Does anyone know what the Denso Part number would be for this car Bank 2 Sensor 2 code P00057?
Thank you-

Try searching, I found this is a couple of seconds https://www.clublexus.com/forums/rx-...numbering.html

Plus a how to do it tutorial https://www.clublexus.com/how-tos/a/...-sensor-366256

I saw this link it didn't help. Right/Front or Left/Rear banks on picture don't fit with piston position.
Also the 234-4400 says Japan cars not North America. 234-4016 says downstream front for North America. Also the cord is 22 in. Dealer part is 10 in cord.
Napa swears its 234-4016. Carquest says 234-4400 and
Toyota has a completely different number.
So yes I saw the link.
Wanted to make sure before dropping the cash. At this point I might buy at dealer.
Thanks anyway and I'll let everybody know if I find an answer to:
Bank 2, Sensor 2 North America/Canada o2 sensor Denso part number for 2011 Rx 350.

What part number does the dealer provide? Have you called the parts department? They usually will provide such information.

What does Rock Auto list?

Dealer part 894650E040 Lexus
Rock auto by description downstream right DEN 234-4400 Japan or Canada or
By cross number 234-4416 same as NAPA.
Toyota tells me 234-4400?

Have you inspected your 02 sensor and measured the wire to determine which cord length you need? That is what I would do to resolve this problem of conflicting advice.

Agreed. Would be denso 4416 10 inch cord. Installed today no codes yet!
