P0011 — Camshaft Position "A" Timing Over-Advanced (Bank 1)
Drive with caution — fix soon.
What P0011 means
This code means the camshaft timing on Bank 1 is more advanced than the engine computer commanded. It usually points to an issue with the variable valve timing system, such as low or dirty oil, a stuck timing control solenoid, or a problem with the actuator. It's a fairly common code and is often fixable without major engine work.
Common symptoms
- Check engine light is on
- Rough idle or slight engine shaking
- Loss of power or sluggish acceleration
- Lower fuel economy than usual
- Occasional engine stalling
Common causes
- Low or dirty engine oil
- Faulty camshaft timing control solenoid (VVT solenoid)
- Clogged oil passages to the VVT actuator
- Failing camshaft phaser or actuator
- Wiring or connector problems at the solenoid
Typical repair cost
$100 – $600
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0011 code?
For short trips, usually yes, but you shouldn't rely on it. The timing problem can worsen and affect performance, so plan to get it diagnosed within a few days.
How much does it cost to fix a P0011?
Repairs often run between $100 and $600. A simple oil change or solenoid replacement is on the low end, while actuator or phaser work costs more.
Is P0011 a serious problem?
It's moderate. It won't usually leave you stranded right away, but ignoring it can lead to bigger timing and engine wear issues down the road.
Could an oil change fix P0011?
Sometimes, yes. The VVT system depends on clean oil at the right pressure, so old or low oil can trigger this code, and fresh oil may clear it.
