Fuel Evaporator Solenoid Valve
Mitsubishi FUSO®

The Fuel Evaporator Solenoid Valve, also known as the EVAP solenoid, is an essential component of a truck's emissions control system. This valve regulates the flow of fuel vapor from the fuel tank to the engine's intake manifold. It works by opening and closing a small passageway in response to signals from the engine control module (ECM). When the valve is closed, it prevents fuel vapors from escaping into the atmosphere, reducing harmful emissions. Over time, the EVAP solenoid can become clogged or fail altogether, leading to rough idling or decreased fuel efficiency. It is important to replace a faulty Fuel Evaporator Solenoid Valve promptly to maintain proper emissions control and prevent damage to other components in the system.
