What does EVAP mean on a code reader?
Evaporative emissions control systems – EVAP for short – are mandated in all cars and trucks. The EVAP system is there to capture these vapors and direct them into the engine to be burned – kind of an on-board recycling program. The EVAP system is a complicated network of hoses, valves, filters and such.
