Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace cam or crank sensors automatically; a performance code can reflect real mechanical timing or oil-control problems.

Useful checks before replacing parts

Review cam/crank correlation data, commanded cam angle, actual cam angle, oil pressure clues, and freeze-frame RPM conditions.
Inspect timing chain or belt alignment, chain stretch, phaser behavior, reluctor condition, and recent timing service work.
Check oil level, oil condition, actuator solenoids, and related cam/crank position codes before replacing sensors.
