I am getting this code, I went to Advance Auto and they told me it was B1S1 for my 2004 Toyota 4Runner 4.7 Limited V8
The lady didn't know much about cars/trucks, she even had problems trying to plug in the computer to my truck port, I had to tell her that there is a cover on the port that has to be removed so she could plug in after watching here struggle for a few minutes. (I didn't want to be rude by telling her how to do it)
Anyways, she looked up on the computer for O2 sensors, I asked her for Denso (because of other driver reviews, its better than Bosch) she looked up Denso 234-4138 for like 70 bucks. I wasn't sure if it was the right one or not, so I am looking for some help.
I found this on
Amazon which says "Fitment Notes: DENSO IS THE OE MANUFACTURER - UPSTREAM LEFT - UPSTREAM RIGHT - OE STYLE " for 59 bucks. not sure if this one needs splicing or not, I rather not splice.
is bank 1, sensor 1 on the upstream driver side?
is this the right image I am looking at?
Please comment back.
