Evaporative Control Systems
Vehicles intended for the North American market are equipped with a gas evaporative control system,
which prevents gas fumes from being released into the atmosphere.
The system consists of an expansion tank in the fuel tank, a check valve at the fuel tank and a charcoal
filter in the engine compartment. The components are interconnected by hoses which channel fuel fumes
from the fuel tank to the charcoal filter where they are stored until the engine is started and then drawn
into the engine fuel induction system.
Evaporative Control Canister
Replace the canister every 45,000 miles.
