Looking at these codes, you have a problem with the 02 sensors on each front side of the exhaust. First check for a blown fuse, then check the connections of the 02 sensors as if water had gotten into the connections it would throw a code. Another cause is a lean or rich condition is being detected. If your problem persists, it says replacing the the 02 sensors on each side front sensors.
