Generator runs but controller logs frequent nuisance alarms without obvious issues

Safety first: Disable auto-start and disconnect battery negative before handling sensors.

• Inspect and reseat connectors: Check all engine sensors (oil pressure, coolant temp, exhaust temp) for secure, clean connections.
• Check grounds: Ensure sensor grounds and engine-to-frame ground straps are tight and corrosion-free.
• Route wiring away from noise: Keep sensor wiring separated from high-current cables to reduce electrical interference.
• Replace suspect sensors: If a particular sensor parameter shows erratic readings, replace that sensor with a Honda-approved part.
