Answer 1

Hi there,

This code is for the sensor AFTER the rear catalytic converter. It's not un common to repair one of the front sensors and have the rear sensor begin to read wrong. It could be because the old sensor wasn't changing the fuel mixture like it should. Chances are good the rear O2 sensor needs to be replaced to resolve the problem.
