What is the meaning of this?
This diagnostic trouble code (DTC) is a generic powertrain code, which means it applies to OBD-II equipped vehicles such as Ford, Dodge, Toyota, VW, Honda, Chevrolet, Hyundai, Audi, Acura, etc.
The crankshaft position sensor (CKP) and camshaft position sensor (CMP) work together to control spark/fuel delivery and timing. Both sensors have a reluctor or tone ring that passes over a magnetic sensor, generating a voltage to indicate position.
The crankshaft sensor is part of the primary ignition system and serves as the “trigger”. It detects the crankshaft’s position and relays that information to the PCM or ignition module (depending on the vehicle) to control spark timing. The camshaft position sensor detects the camshafts’ position and relays the information to the PCM. The PCM uses the CMP signal to identify the start of the injector sequence. The timing belt or chain connects these two shafts and their sensors, ensuring precise timing.
If the PCM detects that the crank and cam signals are out of sync by a specific number of degrees, this DTC will be triggered. Bank 1 refers to the side of the engine containing cylinder #1, and the “B” sensor is likely the exhaust camshaft side.
Note that it is not uncommon to see this DTC in conjunction with P0008, P0009, P0016, P0018, and P0019 on certain GM models. If you have multiple DTCs and a GM vehicle, check for applicable service bulletins for your engine.

Possible Solutions
If your vehicle is still under powertrain warranty, it is recommended to have the dealer perform the repairs.
If you encounter this DTC along with a P0014 DTC on a Chevy Colorado or GMC Canyon pickup, refer to the Densolor Cam/Crank Position DTCs for a possible solution.
If you need vehicle-specific information, please consult a factory service repair manual.
