P0455 FORD Description

  Vehicles that meet enhanced evaporative requirements utilize a vacuum-based evaporative system integrity check. The evap system integrity check uses a Fuel Tank Pressure Transducer (FTPT), a Canister Vent Solenoid (CVS) and Fuel Level Input (FLI) along with the Vapor Management Valve (VMV) or Electric Vapor Management Valve (EVMV) to find 0.040??diameter or larger evap system leaks. Federal vehicles can utilize a 0.040″ leak check rather than the 0.020″ leak check required for California vehicles.
