Engine code p2099 diagnostics code came up on scan . Check engine light on.

It is likely replacement of the sensor will correct this problem but there are no guarantees without proper *hands-on* testing!

I had the same thing with my 2014 Buick Verano and took it to a repair shop. The guys replaced it and the check engine light came back on 4 blocks away. I went back on they said if the 02 sensor didnt fix the problem that it must be the Catalytic Converter (even though Im not having any issues that are typical of a bad Cat) and gave me an estimate of 2k. Im not putting that much into it so I have to drive around with a check engine light on and I cant auto start my car.
