Crankshaft/Camshaft Position Correlation (Bank 2 Sensor B)

Understand P0019, common causes, and the right TOPDON scanner to diagnose it.

Bank 2 exhaust cam correlation fault.

Common symptoms

  • Engine rattle
  • Check engine light

Typical causes

  • Stretched timing chain bank 2
  • Failed VVT actuator
  • Sensor wiring

What scanner do you need?

Enhanced OBD2 scanner (live data graphs, freeze frame, battery voltage test)

Use live data and freeze frame to confirm the fault before replacing parts. ABS, SRS, and network U-codes usually require a full-system scanner.

Diagnostic tips

  • Record freeze frame data when the code first sets
  • Clear the code only after fixing the root cause
  • Check for related pending codes that point to a common issue
  • Verify battery voltage is above 12.4V before chasing sensor codes

P0019 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Which TOPDON scanner do I need for P0019?
Enhanced OBD2 scanner (live data graphs, freeze frame, battery voltage test) See recommended tools on this page.
Is it safe to drive with P0019?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
