P0021 2007 Ford Fusion Code - Intake Camshaft Position Timing Over Advance Bank 2
Quick Answer
The Powertrain Control Module (PCM) monitors the Variable Camshaft Timing (VCT) position for an over-advanced camshaft timing. Common causes include Camshaft timing incorrectly set, Continuous oil flow to the Variable Camshaft Timing (VCT) piston chamber, Erratic camshaft position due to low oil pressure. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
