Direct answer
Generator engine-speed sensing lets the controller verify cranking and running RPM. Related symptoms include RPM loss, under/overspeed or unexpected shutdown. Those symptoms do not prove the component failed: separate no-start from loaded shutdown and preserve history.
What this covers
- electronically controlled generators
- The exact condition described in the title
- Customer-accessible checks before internal repair or reset
What it does not cover
- ×A different brand, model family or similar-looking code
- ×Internal live-electrical, gas, refrigerant or sealed-system testing
- ×A guarantee that a named component has failed without isolation

Correct only the proven, accessible condition
ReversibleCorrect the external prerequisite first. Replacement difficulty is authorized service after battery, load, fuel, airflow and maintenance.
Verify once before going farther
ReversibleRepeat the same controlled stage and confirm the symptom and stored code stay gone.
