P0019 Mercury Code - Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor 'B'

Quick Answer

The Powertrain Control Module (PCM) monitors the Variable Camshaft Timing (VCT) position for a misalignment between the camshaft and crankshaft. Common causes include Camshaft timing incorrectly set, Continuous oil flow to the Variable Camshaft Timing (VCT) piston chamber, Erratic camshaft position due to low oil pressure. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: P0019 Mercury indicates Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor 'B'.
Common causes: Common causes include Camshaft timing incorrectly set, Continuous oil flow to the Variable Camshaft Timing (VCT) piston chamber, Erratic camshaft position due to low oil pressure.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0019 Mercury Description

The Powertrain Control Module (PCM) monitors the Variable Camshaft Timing (VCT) position for a misalignment between the camshaft and crankshaft. The test fails when the misalignment is 1 tooth or greater. This Diagnostic Trouble Code (DTC) can also set due to VCT system concerns (oil contamination or VCT solenoid stuck).
