Many times when we get a series of unrelated codes it can be caused by poor ground connections . You might start with connections from the battery ground to the various parts of the sheet metal of the vehicle. Checking them means , removing , cleaning and reinstalling them. Looking at them does nothing and there are times a connection will appear fine and still be poor. Don't get fooled by appearances.
