Spray the penetrating oil on the O2 sensor and allow it to sit for a good 20-30 minutes or overnight would be even better. Afterward, use an O2 sensor socket wrench to break loose the O2 sensor.

What kind of wrench to use for oxygen sensor?

Oxygen sensor sockets with slotted edges are also quite popular. Wrenches that fit onto the hex-head of the sensor–most commonly a 22-mm or a 7/8-inch drive–accompanied with a square drive in the wrench to accommodate a ratchet extension can be used. Swivels are another friendly tool for access-challenged sensors.
