Crankshaft Position - Exhaust Camshaft Position Correlation (Bank 2)
The P0019 code means the vehicle's onboard diagnostic system has detected: Crankshaft Position - Exhaust Camshaft Position Correlation (Bank 2). This is a moderate severity code.

Common Symptoms
- Check Engine Light illuminated
- Engine runs rough at idle
- Lack of power during acceleration
- Poor fuel economy
- Possible engine stalling
Probable Causes (Ranked by Likelihood)
- Stretched timing chain on bank 2 Very High
- Low or contaminated engine oil High
- Failed exhaust VVT actuator solenoid (bank 2) High
- Worn timing chain tensioner or guides Moderate
- Defective exhaust camshaft position sensor (bank 2) Low
Step-by-Step Diagnostic Procedure
-
Verify engine oil level and condition. Dirty or low oil is a primary cause of VVT correlation faults. Perform an oil change if overdue.
-
Use a scan tool to read camshaft and crankshaft position correlation data on bank 2. Compare actual exhaust cam position to desired position.
-
Test the bank 2 exhaust VVT solenoid by measuring resistance (6-13 ohms typical) and applying 12V to verify plunger movement.
-
Inspect timing chain condition by checking for excessive slack. A timing chain stretch test with a scan tool can measure chain elongation.
-
Check the exhaust camshaft position sensor wiring and connector on bank 2 for damage, corrosion, or intermittent connections.

Timing chain stretch between the intake and exhaust cam on Bank 2 is the root cause on VQ engines. The secondary chain and tensioner in the cylinder head wear out around 100K miles. Replacement requires head R&R. Verify with Techstream-style scan tool showing cam timing offset above 8 degrees.

On 4.0L V6 Frontier/Xterra/Pathfinder, P0019 commonly points to the Bank 2 exhaust cam sensor reluctor or a loose VVT sprocket bolt. Pull the valve cover and check for debris on the tone wheel. Replace cam sensor (Hitachi CPS0005) and reset adaptives.

Low oil level or a clogged VVT solenoid screen will set P0019 on cold starts. Drop the oil pan, clean the pickup tube screen, and replace both bank VVT solenoids. Use Nissan Ester Oil 5W-30 or equivalent full synthetic -- conventional oil kills the phasers.

Can I drive with code P0019?
You can drive short distances at low speeds, but avoid heavy throttle. The engine timing is off on bank 2, which can cause reduced power and potentially lead to further engine damage if ignored.
What does bank 2 mean for P0019?
Bank 2 refers to the side of the engine that does not contain cylinder number 1. On V6 and V8 engines, this is typically the passenger side, though it varies by manufacturer.
Can a bad oil change cause P0019?
Using the wrong oil viscosity can trigger this code. If the oil is too thick or too thin for the VVT system specifications, it cannot properly control camshaft timing. Always use the manufacturer-recommended oil weight.
