Check Engine Light

What is your question?

I can't figure out why the check enging light didn't go out after I replaced the 02 sensor and that was the only code that came up for the light being on, So I changed the 02 sensor and after about 5 minutes of driving the light popped back on so I did the dianostic again and the same code came up so now I'm lost.
