Hi,
I attached the descriptions of each code below. Both are related to the intake manifold chamber. The problem could be a couple of different things, but I would like to first check for engine vacuum leaks. These are known to have seal issues.
Here is a link that explains how to test for vacuum leaks. Try this and let me know the results.

Let me know what you find or if you have other questions. Also, let me know how the vehicle is running.
Take care,
Joe
