Codes P0016 and P0017?

This is serious. Engine has become out of faze /sync/timing etc.
First and foremost do not run the engine until this problem is solved these codes are serious they occur when the ECU has detected a misalignment of the crankshaft in relation to other components especially when it detected both intake and exhaust in the engine like the when this happens sometimes its and indication that the belt or chain has skipped a link or tooth throwing the engines timing components out of sync so the engine shouldn't be started till the problems solved because if what I described has taken place and you start the engine that could be the end of the engine.
Take this vary seriously that said the best way you can find out without starting the engine is to do an inspection of the timing components and also use a bi directional scan tool to get freeze frame data to see what when how it happened and check for othe codes or signs of what other events may have occured sometimes you get these codes when coming has failed or about to fail like a timing chain or belt. Just be extremely cautious with this problem. Good luck
