    2003 Tacoma 4x4, 3.4L v6. Code reader says Bank 1 Sensor 1. So before ordering, I just want to make sure I get the correct one. I would think that its the Up Stream Sensor, correct? The brand I should get for ORM is Denso, correct? Ok, so looking this up online, I'm finding more than one Denso part number for Up stream sensor for my truck. Look at the 1st and 3rd sensors in this pic. What is the correct Denso part number for the Bank 1, Sensor 1 Upstream sensor I need? I'm getting confused here....LOL

    Also, what should I expect to pay for one, and cheapest online place ti buy from?

    Thanks.....

    Is your truck an auto or manual trans? Rock auto is where I got mine and was pretty happy with my purchase.

    Auto trans. Would that be why there are 2 different ones/part numbers?

    Yup, if you look in rock auto they actually tell you upstream for auto trans or upstream for manual trans and whatnot. That picture I put up is a screenshot of my computer with your truck I threw in real quick.

    Edit: Stick with Denso O2 sensors.
