P0011 Code: "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)

🟠 Moderate severity · drivable

Drivable, but the variable valve timing isn't working correctly and is often caused by low or dirty oil, so address it soon.

What P0011 means

The variable valve timing (VVT) system is advancing the intake camshaft timing on bank 1 further than the computer commanded. The camshaft is ahead of where it should be, usually because the VVT oil control can't move or hold it correctly.

Symptoms

Check engine light is on
Rough idle
Reduced fuel economy
Possible rattling at start-up
Slight loss of power

Common causes

most common: Low or dirty engine oil
common: Faulty or clogged VVT oil control solenoid
less common: Worn timing chain or VVT actuator

How to fix it

Fix	DIY?	Typical cost
Change the engine oil and filter with the correct viscosity	Yes	$40–80
Replace the VVT oil control solenoid	Yes	$50–200
Replace a worn timing chain or VVT actuator	Mechanic	$1000–2500

Frequently asked questions

Can I drive with a P0011 code?

Yes, but get it checked soon. Dirty or low oil is often the cause, and running that way can eventually damage the timing components.

What is the most common cause of P0011?

Low or dirty engine oil. The VVT system relies on oil pressure, so an oil change often clears it.

Is P0011 expensive to fix?

Often not — an oil change is $40–$80 and a VVT solenoid is $50–$200. It's only expensive if the timing chain needs replacing.
