Watch your oil level.  If it continues to read higher, you may have a HPFP issue.  Check your fuel trims; if they are reading negative, that's further evidence of failed HPFP diaphragm.  A DTC won't be stored until about -20%.  I'll be replacing mine in the coming weeks; my trims were -5%.  Two UOAs showed trace fuel amounts in the oil.  When I disconnected the PCV line to the intake duct (making sure to seal all open lines to not create a vacuum leak), I saw my trims rise back to near perfect.  That was enough confirmation to order a HPFP and hard line from HPFP to fuel rail distribution block, which is single-use.

 

A CkPS isn't bathed in oil, but because it is reading a tone ring on the crankshaft, gets oil slung on it.  New ones (at least on the other brand vehicles I've replaced them on) have o-rings to seal them and prevent oil leaks.  Just something to watch in the future.

The oil never goes up, it is just overfilled from the oil change.   I take it to this dealership and it ends up costing less than if I did it myself.  Then they also rotate tires and wash it at no additional charge.  But being a bit OCD, I always check the oil level and it's always over the full line by about 1/4 inch or so.  Not enough to be a problem, same guy does all the oil changes and has for years.  The dealership is in a small town that is near to where I grew up and I like going there just to give them support.  It's a 56 mile round trip so I use up some fuel, but I also stop in and visit old friends on way home.
