Charcoal Canister (EVAP Canister)
The charcoal canister stores fuel vapour from the tank so it is not released into the air.
What is Charcoal Canister (EVAP Canister)?
It is the central part of the evaporative emission control system. Activated charcoal inside absorbs fuel vapour. The purge valve later lets the engine draw the vapour in and burn it. Canisters usually last the life of the car if not flooded with fuel.
How it works
Vapour sticks to the charcoal surface and is released when fresh air is drawn through the canister by intake vacuum.
Why it matters for your car
Topping up after the pump clicks off can push liquid fuel into the canister and damage it. A damaged canister or vent valve can cause EVAP codes and a fuel smell.
