Reference meaning
What does this code mean?
The controller detects that camshaft A timing on Bank 1 is too advanced or does not follow the expected control behavior. In the cited Ford and GM applications this is the intake camshaft. Bank 1 contains cylinder 1; its physical side depends on the engine. The code does not identify a failed position sensor by itself.
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
Preserve freeze-frame data and compare commanded with actual cam timing using the correct engine procedure. Check the applicable bulletin and build date before deciding which actuator components need inspection; do not treat a Bank 2 or exhaust procedure as interchangeable.

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.
