P0012 — Intake Cam Over-Retarded (Bank 1, VVT)

P0012 is set when the engine control module commands the Bank 1 intake camshaft to a specific advance position and the actual cam position remains too retarded — the phaser is stuck in or near its base position instead of advancing as commanded. P0012 is the inverse of P0011; both point at the same family of failures but in the opposite direction.
