P0019 Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)

Q: What does P0019 mean?

P0019 means the crankshaft and bank 2 exhaust camshaft signals are out of step, often a stretched timing chain. On bank 2 of a V-engine, the camshaft B signal is out of step with the crankshaft beyond what valve timing can explain, often from timing chain stretch.
