My 2012 had that code last year. I checked the oil control valve screens, they were clear. Also changed the oil, still came back. Ended up replacing the oil control valve with a $20 one from Rock Auto, and that fixed it. Over 5k miles ago.

2. Anyone have any good write ups on how to replace the oil control valve?
3. Any other ideas?
