Answers :

The oxygen sensor looks like a spark plug with wires coming out of the top of it. it is screwed into the exhaust pipe near the engine. disconnect the wires and screw it out of the exhaust pipe turning it counterclockwise then screw the new one in and connect the wires. then clear the codes. one word of warning this is one of the most common codes and does not necessarily mean the sensor is bad. often it will appear if the engine is running too rich or lean because of another problem.
