2011 Ford Mustang GT P0012 and P0014 Codes: Both VCT Systems Faulty? Causes and Diagnosis

I'm having trouble diagnosing an issue with my 2011 Ford Mustang GT. The car ran fine last week, but starting yesterday and continuing this morning, it began feeling noticeably sluggish—like it was down on power. During a merge at lunch, I had to floor the throttle to get moving, and even after that, there was a persistent lack of responsiveness. Shortly after, the check engine light activated. Using my OBD2 scanner, I retrieved two fault codes: P0012 (Camshaft Position A Over-Retarded) and P0-14 (Camshaft Position B Over-Advanced). These codes relate to the Variable Cam Timing (VCT) systems on the dual camshafts in the engine. The fact that both codes are present is unusual—typically, one VCT unit fails at a time. I'm wondering: what's the likelihood of both VCT units failing simultaneously? Additionally, P0014 lists 'System Performance' as a descriptor, which may indicate broader issues with camshaft timing or sensor feedback. Could this be an isolated failure in just the A-side VCT? Or is it possible for both VCT systems on the same cylinder head to malfunction at once? The engine otherwise runs smoothly—no rough idle, no misfires, and no visible mechanical symptoms. This suggests a potential electronic or sensor-related issue rather than a physical one. Any insights from owners of 2011 Ford Mustang GTs with similar P0012/P0014 issues? What are the common causes and recommended diagnostics?
