What's the code p0017 Buick Enclave?

The P0017 code in the Buick Enclave indicates an issue with the crankshaft position sensor and the camshaft position sensor. The code definition states "Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor 'B'". What this means is the sensors are misaligned, have gone bad, or the issue lies with the wiring. A related code is P0016 which is triggered when Sensor A is the problem. Signs and symptoms with this code include failure to start, rattling from the motor, an illuminated service engine light, and poor performance from the engine. When fixing the issue You can first check the wiring harness for any damage. If the sensors have gone bad You can check that using a voltage tester. A jump of the timing chain or if it has stretched will also trigger this code.
