Answer 1

P0031 02 sensor Bank 1 Sensor 1 heater circuit low

P0037 02 sensor Bank 1 Sensor 2 heater circuit low

P0051 02 sensor Bank 2 Sensor 1 heater circuit low

P0057 02 sensor Bank 2 sensor 2 heater circuit low

There is no fuse for the 02 sensor , the 02 wiring connector and harness connector needs to be check, What happens is that water tends to intruded into the wiring connector which leads to terminal corrosion, which may be what is happening to the 02 sensor.
