Hi there!

After you replace the A/F sensor, the self learning must be cleared or the code will reappear.

This is done either with the dealer scan tool, or you can disconnect the battery. If the self learning isn't cleared, the car will continue to run off the old stored fuel trims and cause the code to come back.
