![]() ![]() If the code returns, your mechanic will perform a manufacturer’s specific pinpoint test for the DTC P0011 and fix it accordingly.They’ll also reset to clear the OBD-II fault codes and check if the P0011 DTC comes back. Once done, your mechanic will scan the trouble codes and check the freeze frame data to see when the error code was prompted.The mechanic will change the engine oil if it’s overly viscous or if the oil level is too low. Then, they’ll check if the engine has clean engine oil of the correct oil viscosity.First, they’ll conduct a visual inspection of the Bank 1 intake camshaft to identify any electrical connector, wiring, or valve problems of the camshaft oil control valve.Your mechanic will do the following to troubleshoot and fix the DTC P0011: Stuck oil flow control valve: Oil buildup or contamination causes the VVT oil flow control valve to stick.Now, if the timing of the timing belt is off, it can cause pieces to break off and jump out.These broken pieces could get into the oil pan, causing a drop in oil pressure. The camshaft gears spin by the timing belt when oil pressure drops. Damaged timing components : Some timing components may be damaged, like a stretched timing chain or broken guide.Failing VVT solenoid : There’s a failing VVT solenoid (or oil control valve).Clogged oil control solenoid passages : The oil control solenoid to the Bank 1 camshaft might have blocked passages or is stuck.Extremely thick or dirty oil : The oil is overly thick or dirty, clogging passages and reducing oil flow to and from the camshaft phaser (actuator).Faulty camshaft actuator : There’s a defective camshaft actuator.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).” ![]()
