Intake cam timing over-advanced / performance (Bank 1)
What P0011 means
Your car's computer set P0011: Intake cam timing over-advanced / performance (Bank 1). It belongs to the fuel and air metering group of codes. It is a generic code, so it means the same thing on every make. The check engine light usually comes on once the fault has been seen on two drives in a row. Until then it shows up as a pending code.
Can I keep driving? Usually safe to drive for now, but get it checked soon. Left alone it can lower fuel economy, fail an emissions test or lead to a bigger repair.
Common causes
- Low or dirty engine oil (variable valve timing runs on oil pressure)
- Sticking variable valve timing (VVT) solenoid
- Worn cam phaser
- Stretched timing chain
Fix the cheapest, most likely cause first. Clearing the code without a repair only turns the light off until the fault comes back.
Check it yourself
Check the oil level and when it was last changed first. This is often fixed by an oil change and a VVT solenoid.
