Applicability: For Acura RSX 2002-2004 For Honda CR-V 2002-2004 For Honda Civic 2002-2005 Description: The canister purge valve is installed between the vehicle’s fuel tank and the engine as part of the engine’s evaporative emission control system (EVAP). The canister purge valve works by turning the ECU’s ground circuit on or off at a certain frequency according to different engine operating conditions. The canister purge valve measures this air flow according to engine operating conditions. When fuel evaporates from the fuel system of a gasoline engine, harmful hydrocarbons are released into the environment. The permissible emission level of these hydrocarbons is limited by emission legislation. To minimize hydrocarbon vapor emissions When the engine is turned off, the activated carbon of the car begins to absorb the oil vapor evaporated from the fuel tank, and is firmly fixed in the micropores of the activated carbon in the canister to prevent the oil vapor from leaking into the atmosphere. At the same time, when the car is started, the solenoid valve opens to release the adsorbed fuel vapor as fuel into the intake pipe and enter the engine for combustion. In this way, the canister purge valve can reduce the fuel consumption of the car. Package Includes: 1 * Canister Vapor Purge Solenoid without product instructions;
