Possible Causes
Defective oil level sensor (if equipped), Disconnected sensor harness, Short to ground in sensor wiring, Incorrect sensor installation after oil pan service
How to Fix / Troubleshooting
Safety first: Turn OFF the generator, disconnect the battery, and allow the engine to cool. Do not run the engine with suspected low oil.
- Confirm oil level: Use the dipstick to verify that oil level is correct. If low, top up with the recommended oil and recheck.
- Inspect sensor connection: Locate the oil level sensor on the side or bottom of the oil pan. Ensure the connector is fully seated and free of oil contamination.
- Check wiring: Follow the sensor harness to the control board. Look for pinched or abraded wires that may be shorting to ground.
- Test sensor: Disconnect the sensor and measure resistance or continuity according to the service manual. Replace the oil level sensor if readings are out of specification.
