Oxygen sensors usually are not the problem, they are making you aware (warning) that you have a problem somewhere else.
The oil cap removal method is a very good test for AOS failure. If you experience dramatic RPM fluctuations when removing the oil cap, AOS failure is the problem, not the cap o ring.
