I'm getting the above trouble codes on my car. I replaced the Bank 1, Sensor 2 O2 sensor with an AC Delco. They also checked all my fuses and I'm not having any issues with my car other than poor gas mileage. Does this mean there is (for sure) an electrical issue? One of the reasons I've read this comes up is if there is a poor connection at the O2 sensor itself. Do you know how long this would normally take to diagnose? I'm taking it to the shop this weekend or next and just want to make sure their 2 hour diagnosis fee is accurate.
have the same problem?
