Ask Andy AIP0011 Intake Camshaft Position Timing - Over-Advanced or System Performance (Bank 1)
What it means, what causes it, and what it costs to fix.
What P0011 means
Your engine changes intake cam timing with oil pressure (variable valve timing). The computer commanded a cam position and the cam didn't get there. Most often that's an oil problem or a sticking oil control solenoid.
Can I drive with P0011?
Severity: Medium. Fix soon so it doesn't turn into something bigger.
Drivable short term, but check your oil right away. Low or dirty oil is the top cause, and it can lead to engine damage.
