Answer 1

Hi there,

This code is for the bank 2 catalytic converter. If you have 2 on bank 2, then you replace the converter that's between the two O2 sensors. Without knowing which engine you have in this I can't tell you which bank is bank 2. Just remember you replace the converter between the two sensors
