I'm bored so i'll try to help you. If you look at the top you will see this thread

Which gives you all the codes and what they are.

P0505 Idle Control System Malfunction, I would look at your IAC.

Do a little research using the red search button at the top right corner of your screen https://honda-tech.com/zerosearch. Dont just replace the IAC till you KNOW it is not working. For all you know there could be an open in your circuit and the IAC is just fine.
