P0011
A Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
What it means
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.
Is it safe to drive?
Driving with P0011 can lead to reduced performance and fuel economy. If accompanied by severe engine noise or stalling, it's best to limit driving to prevent potential engine damage.
Most likely causes
Low or dirty engine oil
highVariable Valve Timing (VVT) systems rely on clean, proper oil pressure; old or low oil can hinder operation.
Faulty Oil Control Valve (OCV) / VVT solenoid
mediumThe OCV controls oil flow to the camshaft phaser; if it's stuck or faulty, timing will be off.
Faulty Camshaft Position (CMP) sensor
mediumAn incorrect reading from the CMP sensor can lead the PCM to believe the timing is off.
Stretched timing chain or faulty camshaft phaser
lowMechanical issues with the timing components themselves can cause persistent timing problems.
