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 sensor without checking signal integrity and mechanical trigger condition; a damaged reluctor or wiring fault can set the same code.
