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

What Does P0019 Mean?

Code P0019 indicates that the exhaust camshaft position on bank 2 does not correlate correctly with the crankshaft position. The ECM uses position sensors on both shafts to verify timing is correct, and P0019 is triggered when the deviation exceeds the calibrated threshold. This code is specific to V-configuration engines with dual overhead cams.

Common Causes

• Worn or stretched timing chain on bank 2
• Faulty exhaust VVT solenoid on bank 2
• Worn timing chain tensioner
• Sludge buildup in oil passages
• Damaged camshaft sprocket

Symptoms

• Check engine light on
• Chain rattle on cold start
• Loss of engine power
• Unstable idle speed
• Increased emissions

Diagnostic Steps

1. 1Check engine oil condition for sludge or contamination
2. 2Monitor bank 2 exhaust camshaft deviation angle with scan tool
3. 3Test exhaust VVT solenoid resistance and response
4. 4Inspect bank 2 timing chain and guides visually if accessible
5. 5Perform oil pressure test
6. 6Compare manufacturer timing chain stretch specifications
