    I have a 2003 Limited Tundra 4wd with a v8. I need the right front O2 sensor (bank 2, sensor 1). Searching the various online Toyota parts sites, there are 2 part numbers listed for the right front: OEM 89465-34130 and 89465-34120. I tried looking at the one that currently installed with a mirror and flashlight, but can't find a part number on it. Any idea which one is the correct one?

    Here's a link to a diagram:

    Either one should work. The left and right upstream sensors are the same. If you look at your pic the upstream left has the same part#. Also Denso lists the same part for both with both OE numbers as compatible.

    Also FWIW Denso 234-4169 can be had for about $100 cheaper.

    Thanks! If you look at the pic, both numbers 3 and 4 state that they are front left and right. That's the confusion.

    Is the Denso OEM?

    Yup Denso is OEM. Both part numbers will work for either side they are the same part but Toyota just designates left and right. They do the same for a few different parts.
