An active fuel vapor purge system includes: a turbocharger having a turbine and a compressor; a canister collecting fuel vapor; a purge pump pumping the collected fuel vapor; a main purge line connecting the canister and the purge pump; a first purge line branched from the main purge line and joined to an intake manifold at downstream of the compressor; a second purge line branched from the main purge line and jointed to an intake line at upstream of the compressor; purge control solenoid valves respectively disposed in the first purge line and the second purge line; a hydrocarbon sensor measuring an amount of hydrocarbon; a pressure sensor measuring an upstream pressure and a downstream pressure of the purge pump; and a controller controlling operation of the purge pump based on the amount of hydrocarbon and pressures at a front end and at a rear end of the purge pump.
