Most of the time, a P0011 indicates a timing chain (guide) problem.
Others have said its' been caused by a CPS problem, but most admit it's a timing chaing guide issue.
If it were my car, I'd drop the oil pan & look for broken bits of the timing chain guide.
Hate to bring bad news, and I do hope this isn't the cause of your P0011, but.......chances are......at least you'll know.
