P2270
I get this code (p2270) after replacing the downstream o2 sensor. Mechanic says everything is within of what Chevy recommends. Is there a chance that it’s the wrong o2 sensor or could it be a defective sensor?I got it from Advance Auto and am not sure if it’s a OEM sensor. No evidence of cracked flex pipe or any other exhaust issues. Anything else I should look for? Need it to pass emissions!!

Of course there is a chance it is the wrong sensor or defective. All things are possible.
Posting a link to the Advance auto part would help checking that out.
Check this for some good explanations and things to check:

I replaced it because I had a code that said it was not operating correctly. Don’t remember the exact code. I am not sure if it is a Bosh sensor. I threw the box away. I am going to go to Advance and see if they can pull up which one I bought. I am going to replace with OEM sensor.
