    2000 SR5 automatic with 200k miles.

    Throwing bank 1 sensor 1. Upstream O2 sensor.

    Ordered the part from Rock Auto. It arrives. Plug doesn't match (pic attached). Go to AutoZone and they confirm that the part I got is supposedly the right one. They guy tries looking for answers but all he finds is plugs that appear to match, but are for other model years/transmission/drivetrains
    Any ideas?

    Call your dealer with you vin. Some cars got 02 sensors and some got A/F sensors. The dealer will know and give you the correct part number.

    Also do NOT buy aftermarket O2 sensors. They don't work for crap.

    I bought my Denso 02 sensors off Amazon. They were only about $50.

    You were spot on. Turns out it's a CA emissions truck. Weirdly enough, it's just a different NTK OEM sensor. Toyota and Autozone list it for $350-370. Rock Auto lists it for $157. Same. Damned. Part. ‍♂️

    Glad to help. As long as you can source the OEM supplier...you should be getting a good one. Part number?

    89467-35011 is the correct part per Toyota.

    I have an ‘02 and just did this and it really helped. I used OEM Denso.

    Part #:
    Denso 234-4261 (Downstream)
    Denso 234-9002 (Upstream)

    I ordered directly from Denso and it was $189 for both. Not sure if your ‘00 is different but I would highly recommend the Denso. Good luck!
