What is evap emission comtrol system purge valve on a 2003 ranger 4-cylinder?

The EVAP emission control system purge valve on a 2003 Ranger 4-cylinder is a solenoid-operated valve that controls the flow of fuel vapors from the fuel tank to the engine's intake manifold. The purge valve is opened and closed by the Engine Control Module (ECM) based on various engine operating conditions, such as engine temperature and load. When the engine is running, the ECM opens the purge valve to allow fuel vapors to be drawn into the engine and burned, preventing them from being released into the atmosphere. The purge valve is typically located near the fuel tank or the engine intake manifold.
