What happens if charcoal canister fails emissions test?
Failed emissions inspection: Most states require annual emissions testing. A failed charcoal canister will trigger the check engine light and prevent a vehicle from passing this inspection. When the engine is off, harmful fumes are stored inside the canister by activated charcoal, which is more porous than regular charcoal.

The charcoal canister is the centerpiece of the evaporative emission control (EVAP) system, a technology designed to prevent vapors from your fuel tank from escaping into the atmosphere.
What happens when a canister of charcoal is purged?
When the system needs to be tested for leaks, the valve is used to keep the canister shut. During purge, the valve opens to allow airflow. These operations — purging, venting and system monitoring — are controlled by the car’s computer and are based on information it receives from sensors throughout the vehicle.
