What is an evaporative emission system?
Evaporative Emissions Control The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system at all times. The fuel vapors are then burned in the engine along with the air/fuel mixture.
What are the sources of evaporative emissions?
Evaporative emissions are broken down into five primary sources; diurnal, running loss, hot soak, permeation and refueling.
How do you control emissions?
To control exhaust emissions, which are responsible for two-thirds of the total engine pollutants, two types of systems are used: the air-injection system and the exhaust gas recirculation (EGR) system.
What can be reduced by using an evaporative emission control system effectively?
The purpose of evaporative emissions systems is to reduce or eliminate the release of vaporized HC into the atmosphere. The HC vapors, such as volatile organic compounds (VOCs), react in the atmosphere with nitrogen oxides (NOx) and contribute to the formation of ground level ozone and photochemical smog.
Why does my car have an evaporative system?
When you receive a problem that is related to the evaporative leak, your car’s evaporative emission system ( EVAP) is probably face a fault. The EVAP is there to prevent the fumes (released from the gasoline tank) from polluting the environment and the air inside the vehicle.
What causes an EVAP leak in an engine?
Here are Some Possible Causes for an EVAP Code or an EVAP Leak: Missing or loose fuel cap. Incorrect fuel cap used. Evaporative (evap) emission canister or fuel tank leaks.
What happens when you have an evaporative emission system leak?
When you have an evaporative emission system leak, you have a fault in the evaporative emission system ( EVAP ). Your vehicle’s EVAP prevents gas fumes from the gas tank from polluting the atmosphere and the inside of the vehicle.
What causes an EVAP code to go out?
Here are Some Possible Causes for an EVAP Code or an EVAP Leak: Missing or loose fuel cap. Incorrect fuel cap used. Evaporative (evap) emission canister or fuel tank leaks. Evaporative (evap) emission system hose leaking.

Why does my car have an EVAP code?
Good news for consumers with vehicles not showing any signs of a fuel leak: even if your check engine light is on and you find an EVAP code via the OBD II reading, it might be a simple fix. In other cases, however, it might not be. The most common reason a vehicle shows an EVAP code is because the gas cap is not secure.
