Hi,

I have a 2007 IS250 and last week I got the VSC error light. Since I had it 3 years ago I had a good clue that the wide-band O2 sensor is the issue. At least 1 of them. Error code now is P0031.
My problem is I don't remember which was replaced then... Last time the code was P0051. The question is, are these sensors exactly the same? Which side is which? Bank1 is passenger?
The part number was: 89467-30010 and i see they seems the same.


Appreciate any help.

Thanks
Soma

 

The upstream sensors are the same and the downstream sensors are the same; however, they're different P/Ns because the length of pigtails on each sensor are different.

Bank 1 is the passenger side.

Good luck!

 

Get them from RockAuto.com. Save some cash as you'll be buying the same exact part from the dealer. DENSO OEM

 

thanks, I got a new one and now it works

 

Congrats!!!
