Intake Camshaft Timing Over-Advanced or System Performance Bank 1
The engine computer sees the intake camshaft on bank 1 staying too far advanced or not moving as commanded. This is often caused by dirty or low oil, a bad variable valve timing solenoid, timing chain wear, or a cam phaser problem.
Short trips to a repair shop are usually possible if the engine is running normally, but continued driving can cause poor performance and possible engine damage if timing is off. Do not keep driving if the engine runs rough, stalls, rattles, or the oil pressure warning comes on.
P0011 means the PCM has detected that the intake camshaft timing on bank 1 is more advanced than commanded, or the variable valve timing system is not responding correctly. The fault is usually set when the camshaft position signal does not match the expected position after the PCM commands a timing change.
Yes. Low oil level or low oil pressure is one of the most common causes because the VVT system relies on clean oil at the correct pressure.
Yes. Oil that is too thick, too thin, old, or not approved for the engine can affect cam timing control and set this code.
Not always. A worn timing chain can cause P0011, but oil problems and a faulty VVT solenoid are more common.
Drive only with caution and only if the engine is running normally enough to reach a repair location. If there is rattling, rough running, stalling, or an oil warning light, stop driving and have it checked.
Sometimes. If the cause is low, dirty, or incorrect oil, an oil and filter change may solve it, but the code can also be caused by a bad solenoid, cam phaser, or timing chain wear.
