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 crank sensor before checking reluctor condition and signal quality; mechanical trigger faults can set the code.
Useful checks before replacing parts
- Review crank signal, RPM data, cam/crank synchronization, and freeze-frame conditions during cranking and running.
- Inspect sensor mounting, air gap where applicable, reluctor or tone wheel damage, wiring, connector condition, and recent engine work.
- Check for misfire, stall, no-start, or timing correlation codes that share crank signal information.
