Eric :

Hi. The codes are indicating that you have a vacuum leak. A common spot to look on the sedona is to remove the air intake boot and flip it over. Most likely you will find that there is a split in the boot allowing unmetered air to enter the engine. Check this and for any other vacuum leaks, and let me know what you find. Thanks, Eric
