P0011
A Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
This means your engine's computer sees that the intake camshaft on 'Bank 1' (the side of the engine with cylinder #1) is rotating too far ahead of where it should be, affecting engine performance.
The Powertrain Control Module (PCM) has detected that the intake camshaft timing for Bank 1 is more advanced than the desired position.
Common causes
- high
Low or dirty engine oil
Variable Valve Timing (VVT) systems rely on clean, proper oil pressure; old or low oil can hinder operation.
Typical part cost: $0-100 (oil change)
- medium
Faulty Oil Control Valve (OCV) / VVT solenoid
The OCV controls oil flow to the camshaft phaser; if it's stuck or faulty, timing will be off.
Typical part cost: $50-250 part

Frequently asked questions
What is 'Bank 1'?
Bank 1 refers to the side of the engine that contains cylinder #1. On V-type engines, this is usually one side, while on inline engines, there's only one bank.
Can an oil change fix P0011?
Yes, if the code is caused by low oil pressure or sludge buildup preventing the VVT system from operating correctly, a fresh oil change with the correct viscosity can often resolve the issue.
