Question

I have HYUNDIA 2008 Accent. Last time i am not able to full my fuel tank. As because of vapor its tripped with half only how to solve i found code P0446 AND P0449

Answer 1

P0446 Evaporative emission system vent control circuit

P0449 Evaporative emission system vent control circuit

This code is correct, The name for this component is correct, what it does is vent, When the engine is off , Fuel fumes instead of building up in the fuel tank which can cause the fuel tank to rupture is vented into the charcoal canister where the fumes are store to be consumed when the engine is running. Think of this as a gas can , left in the sunlight it expands, take it to the shade it contracts. This type of movement will shorten the fuel can life span. On the fuel tank to control this there is a vent control solenoid, This is the one at fault.
