P0011: "A" Camshaft Position - Timing Over-Advanced (Bank 1)
What it means
Bank 1 intake cam timing is more advanced than the computer commanded, often because oil isn't controlling the cam phaser correctly.
Severity: Medium Over-advanced cam timing can cause rough idle and stalling; ignoring low oil can damage the timing chain.
Common causes
- Low or old engine oil
- Sticking intake oil control solenoid
- Clogged solenoid screen
- Worn cam phaser or stretched timing chain
Most common causes first. Exact causes vary by make, model and engine.
Can I fix it myself?
Often DIY. Check oil level and do an oil change with the correct grade before buying parts.
