Crankshaft/Camshaft codes

Hey guys, I have a 2011 Mustang GT that recently bought. The check engine light came on with a P0012 and P0017 codes.
I'm needing help finding the problem. I've checked the oil and it's full and clean. I've tested the vvt solenoids and they read 8.4 ohms, and I tested the connectors going to them and they have 11.5 volts. I haven't tested anything else yet. Is this a common problem? It has 155,000 miles on it. The engine is all stock.

I took the valve cover off and the pin on the vvt solenoid on the intake side was stuck out, wouldn't move. Also, the pin in that cam phaser looks chipped. Will that be okay? If not, can I replace just the pin, removing the 3 bolts?
