Default Passing emissions

Every few hundred miles a code comes up for p16839 (o2 sensor). If I clear the code before the test, will it pass emissions? I need to get it done soon so any feedback would be appreciated.

Default RE: Passing emissions

If it keeps coming back, you have a bad o2 or cat. Search the code and see which it is. The code will be in the ecu before the cel will come on and could stil cause you to fail
