P0463 Suzuki Code - Fuel Level High Voltage
Quick Answer
The Engine Control Module (ECM) uses the signal from the Fuel Level Sensor to calculate expected vapor pressure within the fuel system. Common causes include Faulty Fuel Level Sensor, Fuel Level Sensor harness is open or shorted, Fuel Level Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
