Generator shuts down, controller displays E-10, oil level appears normal

Safety: Disable automatic start and allow the engine to cool before checking oil.

• Confirm oil level: Use the dipstick to verify oil level is within the marked range. Adjust if necessary.
• Inspect oil level sensor: Locate the oil level sensor on the oil pan or crankcase. Check the connector for corrosion, oil intrusion, or loose fit. Clean and reseat the connector.
• Check wiring harness: Follow the harness from the sensor to the controller. Look for chafed insulation or pinched wires. Repair or replace damaged sections.
• Level the generator: Ensure the generator base is level. Excessive tilt can cause false low-level readings on some sensors.
• Clear code and test: Clear E-10 and run the generator while monitoring for reoccurrence.

If the sensor continues to trigger falsely, replace it with a CAT-approved oil level sensor. If the code persists after replacement, the controller input may be faulty and should be checked by a technician.
