Default O2 Sensor Codes. What does this mean?

All I know is these codes mean the voltage to the O2 sensors are low. What exactly does this mean? Do I need new O2 sensors?

For the last few years my check engine light will come on every so often when I floor it. It always goes off after awhile and I never noticed a difference in the way the car drove. Now it is on and there is lag in the acceleration.

It's very odd that all 4 sensors would report low voltage. I suspect a a bad ground even though I think grounds are misdiagnosed frequently on CF. Perhaps someone with a service manual handy can verify they share a common ground. I would think the 02s must.

The engine light is off now but the car is still sluggish.
