Briggs & Stratton PowerProtect 22kW Standby Generator with Symphony II Controller LOW-OIL-PRESSURE Error Fix: Low Oil Pressure — Engine Protection Shutdown

Error code LOW-OIL-PRESSURE on the Briggs & Stratton PowerProtect 22kW Standby Generator with Symphony II Controller means: Low Oil Pressure — Engine Protection Shutdown. The oil pressure sensor detected critically low oil pressure, and the controller shut down the engine to prevent bearing damage. This is the most critical fault — running an engine without adequate oil pressure will destroy it within minutes. Check the engine oil level immediately using the dipstick — add the correct oil type (typically SAE 5W-30 synthetic) if low. Oil consumption increases with engine hours. If the oil level is adequate but the fault persists, the oil pressure sensor may be faulty, the oil pump may be failing, or there may be an internal engine bearing issue. Do not override this shutdown — have a dealer diagnose the cause.
