Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor B

Where it lives

For P0019, start at the sensor the description names. The description of P0019 puts it on bank 2.

Check these first

• A stretched or jumped timing chain on bank 2
• A dirty or failing bank 2 camshaft position sensor B
• A failing crankshaft position sensor
• Corroded or loose connectors in the correlation circuit
• Wear in the bank 2 camshaft phaser

What to do next

1. Read the freeze frame and note the engine speed when the code set
2. Compare camshaft and crankshaft signals on a scan tool
3. Inspect the bank 2 timing chain and tensioner for stretch or jump
4. Check the bank 2 camshaft sensor B and crankshaft sensor connectors
5. Crank the engine and watch both signals stay in sync
6. Clear the code and retest
