Spray the threaded sensor area with PB Blaster (cold engine). Disconnect electrical connector, use large socket or wrench to remove.
This car is equipped with two sensors, upstream and downsteam. You would have to get under car to get to the downstream (located after CAT).
When installing ALWAYS use an antisieze compound on the sensor threads. Some sensors come with it already coated on the threads or a small packet.
