anyone else have this problem? I'm trying to find a fix for it. Someone said my O2 sensor is probably dead. If I get a replacement how can I prevent this next time around?

Got the same CEL code. Not sure if it was the same CEL before I put the CEL fix. But that's what the code reader spit out after the CEL fix was installed. Does this mean I'm goin to be change rear 02 sensors soon?

 

yea sounds to me like a dead sensor.... how many miles on it?

 

Had about 27000 miles on the car when the code came up. It actually appeared after 200 miles of driving the car with my turboback exhaust newly installed.
Also Will the dealer replace the O2 sensor even if they see the full turboback exhaust on? Will they give me a hard time?
