Mazda5 O2 sensor location and fuse?

[Buck Mulligan]

Looking for 2008 Mazda5 O2 location for Bank 1 Sensor 1, and the location of the fuse (did not see anything referring to "O2" in the box). Getting codes P0134 and P2243. I'm going to attempt to replace the sensor myself (If needed. Will check the fuse first). Any help with a part number and/or an affordable aftermarket part would be appreciated, as would any helpful tips.

O2s dont have fuses as far as I know. Judging by those codes it looks like either the wire broke or the sensor just up and failed.
