Reference meaning
What does this code mean?
This is the Bank 1 camshaft B over-advance/performance code. In the cited applications B is the exhaust camshaft, while P0011 concerns intake. A timing-control fault can involve the actuator mechanism rather than the position sensor; the code alone does not establish which component has failed.
Sources and interpretation [1]
A code identifies a detected condition, not a part that must automatically be replaced.
Narrow by vehicle
A listed vehicle is a research lead. Confirm the engine, production range and software in the manufacturer's information.
Manufacturer example · limited applicability
GM 21-NA-146 concerns 2019 Silverado 1500/Sierra 1500 New Model with the L3B 2.7L engine. It describes a possible broken spring in an actuator solenoid bolt. Repair selection depends on inspection and whether production was before or after 20 March 2019; it is not a universal cam-sensor replacement instruction.
Before replacing a part
Confirm exhaust-side identification and compare commanded and actual timing. On the specific GM L3B application, the bulletin distinguishes repairs before and after 20 March 2019; that build-date rule must not be generalized to other engines.

Can I keep driving?
A code alone cannot establish whether driving is safe. A flashing malfunction light, severe shaking, overheating, oil-pressure warning or loss of braking or steering needs prompt attention. Stop in a safe place and seek assistance when control or engine safety is affected. Follow the vehicle handbook.
