Where is the locations of the O2 sensors on a 2007 Mazda 6 2.3L V4

I have trouble codes showing that the O2 sensor are bad and also my engine ignition fuse has blown out twice and want to know if there is a diagram that can show me where all the sensors are located so I can also see if there is any loose wires.

Answer this question I have this problem too

Is this a good question?
