Engine Oil Pressure Control Circuit Open
 

Jawg, I believe I had this code show up on my 2012 with 29,000 miles. I wrote it down somewhere. Anyway I believe it was explained to me that it has to do with the one piece oil pump/solenoid assembly. The code is reading that the oil pump is running on high oil pressure at all times, it's a 2 stage pump controlled by the solenoid going from high to low oil pressure as throttle rpm's are varying. Dealer at the time told me oil pump was good, so they replaced the oil pressure switch. A week later, had the same code, then they replaced the oil pump/solenoid and a wiring harness between the two. So if I recall, it's an issue between the oil pump or the oil pressure switch. I believe even to replace the pressure switch, the manifold had to be removed. Hopefully this at least gets you in the right direction and my memory is still good. Good luck.
