Don't over use the code reader. A bum O2 sensor that has created a code will cause the code to go away when replaced and working. You didn't have to clear the code, the ECU is smart enough to do that on its own.

Perhaps it is your cheap code reader? :) Instead of clearing just one code at a time, it flushes everything?

I do not believe a drive cycle can be completed with an error outstanding, but an error should not clear the drive cycle.
