2004 Ford F150 5.4L P0012 Fault Code: Camshaft Position Timing Over-Retarded Bank 1

I recently ran a diagnostic on my 2004 Ford F150 Lariat with the 5.4-liter engine and received trouble code P0012. When starting the truck, I hear a severe knocking noise, which is likely caused by valves opening and closing at incorrect intervals due to improper camshaft timing. The issue appears to be a camshaft position timing over-retarded on Bank 1. This fault code indicates that the engine control module has detected an abnormal camshaft position, leading to inefficient valve operation and potential engine damage if not addressed promptly. Repairing this condition requires correcting the camshaft timing alignment, typically through adjusting or replacing the timing chain or tensioner, depending on the specific component failure.
