pop out the center trim piece with a flat head screwdriver. Center dash piece may be brushed aluminum or wood grain depending on trim level. It should pop out easily working all the way around it. Then radio is held in with 7mm screws.

There is a special socket for O2 sensors which allow the wires to stick out and not get twisted up. It's not expensive and available at most auto parts stores. Disconnect the sensor from the wiring harness, with the plug and then use the socket to remove and replace the new sensor. Re-connect electrical plug.

Chevrolet Impala comes equipped with two oxygen sensors, one on either side of the catalytic converter. Locating the sensors is as simple as crawling under the vehicle.
The bank 1, sensor 2 oxygen sensor is located downstream of the catalytic converter. To get to the sensor, crawl underneath the vehicle and trace the exhaust pipe until you reach the catalytic converter. Continue to follow the exhaust pipe until you reach the bank 1, sensor 2 oxygen sensor.
You should be able to identify the oxygen sensor as a single wire about 3 to 6 inches long. The oxygen sensor is mounted to the exhaust pipe and should slightly protrude from the pipe.
The oxygen sensor is an important part of the vehicle exhaust system. The sensor tests the amount of air in the exhaust stream. It then sends this information to the engine control computer, which determines how much fuel is necessary to maintain a proper air-to-fuel ratio.
