    Ok my truck has trown a code that says this is bad. I cleaned the Mass air valve last night and will think about changing out the sensor if it throws it again. I have a stock double cab 2001 3.4 v6 and I live in Arkansas. I am having troble finding what I need. I have a couple of questions. 1. how do I know if this is Ca model. I know I am the second owner and we both live in Arkansas. 2. I can't tell what model. I have looked at a couple of links when I did a search and still cant find what I need. Help will be appreciated. Rick

    Just sent someone to this website: www.rockauto.com last night. Saved him 40 bucks on an O2 sensor over everywhere else could find them, and got overnight shipping to boot.

    Just follow the bouncing ball there, you'll find what you need. O2 sensors are under the "Emission" group

    Why not buy a factory O2 sensor? You shouldn't have any worries of it not working properly (assuming that is the cause of the problem).

    http://trdparts4u.com/ has good pricing and also try www.partznet.com

    Neither of those sites show they sell a upstream sensor for the 01? Odd for sure (or I'm boneheading the search).

    The factory sensor is Denso. Same rockauto sells.

    It's a website and they can't possibly have everything listed.

    Grab their phone numbers, give them a call directly. They are both Toyota dealers and should have everything/anything you need.

    FYI. Your first sensor is an Air/Fuel Ratio Sensor (heated Oxygen Sensor) but mine went and i tried other brands that didn't work...go factory on this part and save yourself a lot of problems.

    you should have two sensors. the first one is Bank 1 Sensor 1 and the second is Bank 1 Sensor 2
    Sensor 1 - A/F sensor
    Sensor 2 - O2

    Used the Innova 0330f scanner. Good scanner, does ABS too, for around $50.

    The online diagnostic help seems to be a waste of time because it doesn't show any diagrams, just $495 to have it repaired.

    Sheeet, a good mechanic should be able to knock it out in a half-hour. Toughest part will be the plug end nested on top of the trannie. :eek:


    Rock Auto, here I come!!!!! :D

    Damn, can't find the upstream/heated sensor.

    FOUND IT! more coffee................................
