2007 Chevrolet Cobalt with engine code P2A01

Question

I got an engine light on my car, so I got it checked out and it came back with code P2A01. I got the light turned off, but what should I do from here?

Answer 1

HI there
This code is an issue with the rear O2 sensor on bank 1. This is usually a problem with the sensor itself, if you simply cleared the code without doing any repair, it will continue to come back.
