2011 rrs sc Clanking from oil fill

[Kenney14]

My 2011 rrs supercharged check engine light came on with restricted power alert but there were no sounds are vibrations or anything. Went to parts shop to get the code read and it came back Crankshaft Position-Crankshaft Position Correlation-Bank 2 Sensor B. When I started it back up there was a weak idle with clanking/grinding sounds which I discovered were coming from the oil fill, then the car died. Please Help!
