#Intake camshaft position timing code

Advanced camshaft : The camshaft is excessively advanced when the Engine Control Module has instructed the camshaft to hold back to a lower timing level.

Stuck camshaft phaser: A camshaft phaser (camshaft actuator) is stuck in the advanced position.

Sensor readings: The camshaft sensor and the crankshaft sensor suggests that the camshaft is more advanced than the Engine Control Module has directed it to.

Here are some instances that cause the code P0011: The engine computer adjusts the camshaft or camshafts using an oil control valve or valves (OCV), also called a variable valve timing control solenoid valve. The process is used to improve fuel economy, engine performance, or emissions by regulating when the intake and exhaust valves are closed and opened. Variable valve timing (VVT) or variable intake valve timing is the process of changing the timing of an intake valve lift event in internal combustion engines. Note : This specific OBD2 fault code is triggered mainly in cars with variable camshaft timing (or variable valve timing ). In simpler words, your car’s Engine Control Module is indicating that the timing on your vehicle’s intake camshaft is out of alignment. Over-advancing can occur during advancing or retarding of the camshaft timing (cam timing). It means that the Power Control Module (PCM) or Engine Control Module (ECM) has detected that the Bank 1 intake camshaft is more advanced than what the PCM (or ECM) commands it to be.

By definition, this generic OBD-II code means: “Camshaft Position A – Timing Over-Advanced or System Performance (Bank 1).”
