What is evaporative emission control system
An EVAP leak is a fault in the evaporative emission control system EVAP. The evaporative emission
control system function is to keep gasoline fumes in the fuel tank from reaching the atmosphere. This
keeps air pollution down and keeps the stink of fuel from attainment the inside of your car. Fuel vapors
are emitted from car any time there is petrol in the tank. So if you have a leak still if you are not driving
the vehicle those gases are polluting the air 24 hours a day.
Is it Safe to Drive with an evaporative emission control system Leak
‘Yes’. However this doesn’t mean that you should. The evaporative emission control system in your car
serves to contain the fumes that are created by fuel in your tank. These fumes have to be prevented
from getting into the atmosphere so that they will not contribute to the already-worsening air pollution.
So yes you can still drive your vehicle safely as it really doesn’t have a bearing on the overall
performance of your car.
slide 2: Why There Can Be Leaks:
A leak in the Evaporative emission control system can occur almost anywhere. It can be because of
damage to the hoses that convey the gasoline fumes to the engine. As everyone knows hoses are
not exactly immune from damage. Over time they can become brittle and form cracks where
fumes can escape. It is also likely that one of the EVAP hoses has been detached allowing the
vapors to run away.
Another potential cause of a leak in the Evaporative emission control system is leaks in the charcoal
canister itself. Again these can degrade over time because of corrosion or exposure to impact
forces. The canister itself can get cracked allowing vapors to hiss through the small opening. The
canister can get severely damaged that your only recourse is to have it replaced.
Other causes of EVAP leaks can include faulty vent control valve or the purge valve. These valves
can get stuck in their respective openings too. When stuck they will not be able to function
normally and will not be able to purge the stored gas vapors into the engine’s intake valve. It is also
likely that there’s a problem in the leak discovery pump or any other leak in the car’s fuel system.
