Check engine light on autozone says oxygen sensor needs replacement on 2007 Toyota Corolla

Is the oxygen sensor covered under the Federal emissions law car has less than 80,000 miles. Toyota first said yes and when I went to make appointment they said no. Check engine light has been on for six months.

Only the catalytic converter is covered under this warranty. So no the oxygen sensor is not covered under the warranty.
