NISSAN 14930-AH10A Control Valve

The genuine NISSAN 14930-AH10A control valve (Valve Control / EVAP purge valve) is a key component of the engine emission and fuel delivery system. Controlled by the engine control unit (ECU), the valve's function is to precisely regulate the return of fuel vapors stored in the charcoal canister back into the combustion chamber, preventing polluting evaporative emissions and ensuring stable air-fuel mixture formation.
