Purge valve (solenoid). The purge valve is the part of the vehicle Evaporative Emission Control (EVAP) system. The EVAP system prevents fuel vapors in the fuel tank from escaping into the atmosphere. The EVAP system traps fuel vapors from the fuel tank and temporarily stores them in the charcoal canister, see the diagram.
Factors that can affect the performance of a canister purge valve include unclean valve conditions and valve blockage. Valve blockage is caused when an obstruction becomes lodged in the opening of the valve, causing a backup of the fuel and air mixture.
