Your P1416 is a "history" code so I would clear it and see if it returns...this code relates to a bank 2 (passenger side) AIR system fault. The code description is below...the AIR check valve which is behind the intake manifold gets "gummed" up best case scenario or worst case is defective. Try removing the hose (arrow in picture) on the driver side check valve and spray some Brake Kleen or something similar into the hose and if you have an air compressor blow it into the hose...hopefully the Brake Kleen will find its way back to the bank 2 check valve behind the manifold and free it up...you can try this a few times.
