P0019 code definition

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

What the P0019 code means

P0019 is the OBD-II generic code indicating that the crankshaft and Variable Valve Timing (VVT) position sensor B for bank 2 exhaust camshaft does not correspond signals with each other.

What causes the P0019 code?

  • The VVT is out of the position that the Engine Control Module (ECM) correlates with the crankshaft.

  • Oil pressure to the VVT has blocked passages through the camshaft.

  • The Oil Control Valve (OCV) is stuck in one position.

  • The camshaft gear phaser is not adjusting and is stuck in one position.

What are the symptoms of the P0019 code?

  • The Check Engine Light will come on to indicate a problem with the camshaft timing.

  • The engine idle may be normal, but the engine may hesitate on acceleration.

  • The engine may run rough or erratic above idle.

  • Due to the camshafts not being in the optimal positions, the fuel mileage will be less than before the problem occurred.

Note: Drive complaints will differ between vehicles depending on the manufacturer's failure mode.

How does a mechanic diagnose the P0019 code?

  • Checks for problems with the OCV, and camshaft and crankshaft sensor connectors and wiring.

  • Engine oil should be full of clean and correct viscosity oil.

  • Scan and document the engine codes, then view the freeze frame data to see when the code was set.

  • The Check Engine Light should be reset and then road tested again to see if the code returns.

  • Command the OCV on and off to see if the camshaft sensor is indicating timing changes for the bank 2 exhaust camshaft.

  • Perform the manufacturer’s tests for the P0019 code to determine the cause of the code.

Note: The manufacturers recommend a pinpoint test to narrow down the problem. Following the recommended tests will help with diagnosis and prevent you from replacing the wrong parts.

Common mistakes when diagnosing the P0019 code?

Follow these simple guidelines to prevent mistakes:

  • Always verify that the failure and codes are active for a proper diagnosis.
  • Do a visual check of the wiring and connections to verify whether they are damaged.
  • Do all pinpoint test steps to help prevent misdiagnosis of good components.
  • Only repair or replace parts when directed by the pinpoint test or a visual check.

How serious is the P0019 code?

  • The engine carbon build up may cause fouled spark plugs, causing misfires.

  • Timing chains may have tensioners or guides that are allowing the timing chain to jump the gear teeth, leading to major engine damage from valves and pistons hitting.

  • Driving the vehicle for a prolonged time with the camshaft problems can start to cause other drive symptoms like misfires, stalling, and no starts.

What repairs can fix the P0019 code?

Additional comments for consideration regarding the P0019 code

Code P0019 and code P0017 are the same problems but for the opposite side of the engine. If both of these codes are received at the same time, then both sides of the engine are having the issue and the problem may be oil pressure related, or the passages to the oil control valves are blocked for sludge build up, or the wrong oil is being used.
