Answer 1

Hi there,

This code is for the bank 2 catalytic converter below threshold. This generally means the converter is not working properly. If the O2 sensor is no good, it will be the one on the driver side of the engine AFTER the catalytic converter. Most often with these the converter is the actual issue and it will need to be replaced.
