Evaporative Emission Control Canister: Description and Operation
Evaporative Emission Canister
PURPOSE
The Evaporative Emission (EVAP) control system uses a canister filled with charcoal to absorb fuel vapors from the gas tank.
OPERATION
When gasoline vapor will flow to the canister where it is absorbed and stored by the charcoal. Under certain operating conditions the Powertrain
Control Module (PCM) will command the purge solenoid valve to open. This allows the vapor to flow into the intake manifold for combustion.
