P0019 Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor B

P0019 indicates crankshaft and camshaft position correlation on bank 2 sensor B. The cam-to-crank relationship is outside the expected window.

Code details

Generic OBD-II · P0

System: Fuel / Air
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not clear a correlation code repeatedly; unresolved timing faults can lead to drivability problems or engine damage.

Symptoms of P0019

Check-engine light on, sometimes with rough or uneven running.
Hesitation, surging, or a noticeable change in fuel economy.
Occasionally hard starting or a smell of unburnt fuel.

Common causes of P0019

A failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor).
Intake or vacuum leaks, or an exhaust leak near an upstream sensor.
Wiring, connector, or fuel-delivery problems that skew the reading.

Useful checks before replacing parts

Compare bank 2 sensor B cam data with crankshaft position, commanded cam timing, actual angle, and freeze-frame operating conditions.
Inspect timing components, cam actuator movement, oil level and condition, VVT solenoid operation, wiring, connectors, and reluctor integrity.
Review whether the fault appeared after timing service, low oil pressure, extended oil intervals, or with related cam timing codes.
