P0430 Toyota - tundra what sensor should I replace

Question

I have 4 O2 sensors I guess left side is bank 1 and right side bank 2 which one should I replace when p0430 is showing bank 2

Answer 1

Hi there,

There are 2 V8 options on this truck, both bank 1 is the driver side and bank 2 the passenger side. For this code you would want to replace the passenger side rear O2 sensor. Behind the converter. Typically though the issue is with the catalytic converter itself.
