Evaporative emission control systems (EVAP) are used in cars' fuel systems to prevent gasoline fumes from leaking into the atmosphere. The EVAP system runs diagnostics for possible fuel vapor leaks ...

Automotive evaporative emission control system (EVAP) seals the fuel system and prevents fuel vapors from escaping the vehicle and contributing to pollution. Uncontrolled emissions account for 20% ...

A look at 1970 to 1982 Corvette Evaporative Emission Control. This system, EEC or ECS, prevents gas tank vapors from escaping and creating smog.

Vehicles such as the Honda Civic and Honda Accord may set the manufacturer-specific code P1457, known as an EVAP Control System Leakage (EVAP Canister System).
