Take a look at this website to see your codes. I couldn't find the P0118, you may want to re-check that.
As for clearing the vehicle, depending on what type of scan tool you have will vary on how this is done. Take a look at your owner's manual or try to search on-line for your model if you don't have it. You should be able to choose another vehicle.
