P0014

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.

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.
