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 the cam sensor before checking mechanical timing and signal quality; range faults can be caused by timing movement.
Useful checks before replacing parts
- Compare camshaft and crankshaft signals, synchronization data, and freeze-frame conditions from the fault event.
- Inspect sensor connector fit, wiring, mounting, cam trigger condition, and recent timing or cylinder-head service.
- Check for timing-chain stretch, phaser faults, or correlation codes that can make the cam signal appear out of range.
