P0498 KIA Code - Evaporative Emission System Vent Valve Control Circuit Low
Quick Answer
The Evaporative Emissions (EVAP) system prevents Hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Common causes include Faulty Canister Close Valve (CCV), Canister Close Valve harness is open or shorted, Canister Close Valve circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
