What engine is in this vehicle? I assume the avalon would be a 3.0L or similar V6 engine. Bank 1 sensor one indicates one of the primary O 2 sensor controlling a/f ratio. Sensor one bank one would be the sensor located in the Front manifold, closest to the engine. Hope this solves your issue. I would first check the conector at this sensor for corrison before buying a new sensor.

O2 sensors are tricky. sometimes like anything else they fail. many times though the exhaust mixture they encounter is out of their range and that shows up as a failure.since you seem to have no other problems , I would go ahead and change them, but don't be disappointed if the code shows up again (at least you know it's not the sensors.) I don't like using the process of elimination when doing repairs but sometimes you must.

check for intake manifold for vacuum leaks, use a can of spray carb cleaner and spray around the top of the engine, if you hit a leak the engine idle will change, P0302 is a miss in #2 cylinder (cylinder power output low, lean cylinder due to poss vacuum leak and other issues.). once again an O2 will not cuase a mis-fire.
