P0011 Camshaft Position Timing Over-Advanced (Bank 1, Intake)

What it means

The intake cam timing on bank 1 is more advanced than the computer commanded. This involves the variable valve timing (VVT) system.

Severity: Moderate

Can I drive it? Short trips OK if it runs fine; rough running or stalling means stop and fix. Check oil level first.

Common causes (most likely first)

Low or dirty engine oil / wrong viscosity
Faulty VVT oil control solenoid
Sticking cam phaser
Stretched timing chain

Likely fixes

Check oil level; change oil with correct grade
Test/replace VVT solenoid
Inspect timing chain/phaser
