The evaporative emissions (evap) control system is typically located in the fuel tank and includes components such as the charcoal canister, purge valve, and vent valve. These components work together to capture fuel vapors from the tank and prevent them from escaping into the atmosphere. The system is commonly found in the engine compartment or near the fuel tank, depending on the vehicle's design. Regular maintenance of the evap system is essential for optimal vehicle performance and compliance with emissions regulations.
