Well I can tell you for sure one of the codes. The P1400 is a Egr code. Most common is the Egr pipe with the EGR temp sensor in it gets all carboned up and get clogged. I would remove that pipe and check it. If clogged, it will need to be cleaned and I would also check the EGR passage in the plenum. That could cause a close loop code. I would start by cleaning those passages clearing the codes and see if the 150 code comes back.

If you have any more questions on this, please feel free to ask. Thanks Jay!
