    I have a 99 v6 PreRunner that is showing a PO420 code, which I have read has to do with the catalytic converter, but it seems most people say to try replacing the o2 sensors first.
    I was going to do just the one behind the Cat and see what happens from there (unless it's better to just do both at the same time).
    Was looking at the
    $61 Denso 234-4189 Oxygen Sensor
    Denso 234-4189. Is that the correct part number?

    Do you have an auto or manual transmission. But that number you have is wrong either way.

    It's an automatic. Good thing I didn't order it haha.
    I'm a noob when it comes to truck stuff.
