To erase codes with the scanner I use you just have to hold erase on the error code it would clear it.

You can ignore the misfire, fuel, comp etc. I said it was a simple code reader, it only reads error codes, allows you to clear them and tells how many readies your car have.

Your codes indicate a failed air pump and both o2 sensors being bad. You said you replaced both o2 sensors, you need to clear the codes and drive it around until your car has went full ready again. If the problem is resolved it wont throw any codes if it is not it will throw a light and you'll need to read it again.
