P0019 Crankshaft Position Camshaft Position Correlation Bank 2 Sensor B 2

OBD-II Code P0019: This code indicates a problem with the correlation between the crankshaft position and camshaft position for bank 2, sensor B. The engine control module (ECM) detects that the timing of these components is out of sync.

Description: The ECM monitors the relationship between the crankshaft and camshaft positions to ensure proper engine timing. If it detects an issue where these components are not aligned as expected, it triggers this fault code.

Definition: P0019 refers to a misalignment or incorrect correlation between the crankshaft and camshaft positions on bank 2, specifically affecting sensor B. This can lead to poor engine performance, increased emissions, or even prevent the engine from starting.

P0019 – Crankshaft Position Camshaft Position Correlation Bank 2 Sensor B

Severity: Moderate

Common Causes

P0019 – Crankshaft Position Camshaft Position Correlation Bank 2 Sensor B

Common causes of this OBD2 code:

• Incorrectly installed or faulty camshaft position sensor
• Timing chain or belt misalignment or issues
• Faulty crankshaft position sensor
• Engine mechanical problems, such as low oil pressure or engine damage
• Wiring issues in the camshaft position sensor circuit
• ECU/PCM software needs to be updated

 

Common Misdiagnosis

OBD2 Code: P0019

Description: Crankshaft Position – Camshaft Position Correlation Bank 2 Sensor B

Common Misdiagnosis: Replacing the camshaft or crankshaft position sensors without checking for timing chain/belt issues, wiring problems, or mechanical engine faults.

 

Common Diagnostic Steps

OBD2 Code: P0019

Description: Crankshaft Position – Camshaft Position Correlation (Bank 2 Sensor B)

• Verify the code with an OBD-II scanner and clear it to see if it returns.
• Inspect the wiring and connectors related to the camshaft position sensor for damage or disconnection.
• Check the timing chain or belt for proper alignment and wear.
• Test the camshaft position sensor using a multimeter to ensure it’s functioning correctly.
• Examine the crankshaft position sensor for any signs of damage or malfunction.
• Ensure that there is no debris or obstruction affecting the sensors’ operation.
• If applicable, update the vehicle’s engine control module (ECM) software to the latest version available from the manufacturer.
• If all else fails, consider replacing faulty components such as sensors, timing chains/belts, or ECM after confirming they are defective.
