OBD2P0019
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Crankshaft Position - Camshaft Position Correlation.

Severity

moderateCan drive, but performance issues and potential engine damage may occur if not addressed.

Summary

Code P0019 indicates a correlation issue between the crankshaft position and camshaft position sensor B on bank 2 of the engine. This code suggests that there is a problem with how these sensors are communicating timing information to the PCM.

Symptoms

  • Engine runs poorly
  • Engine cranks but does not start
  • Check Engine Light illuminated

Common Causes

  • Faulty cam or crank sensor
  • Open or shorted circuit in the cam or crank sensor wiring
  • Timing belt/chain out of sync
  • Slipped or broken tone ring on camshaft or crankshaft
  • Problem with the VVT system
  • PCM malfunction

Diagnosis

  1. Visually inspect sensors and connections for any obvious faults.
  2. Test the sensor output using an ohmmeter or multimeter depending on whether it is a permanent magnet or Hall Effect type.
  3. Check the sensor circuits for proper voltage and continuity to the PCM.
  4. Use an oscilloscope to test synchronization between crankshaft and camshaft sensors.

Fixes

  • Replace faulty sensors, repair wiring issues, adjust timing belt/chain if out of sync, or replace VVT system components as needed.
