Ford's Evap System: Operation & Testing | MOTOR Ford's Evap System: Operation & Testing. The powertrain control module (PCM) uses three simple but robust components to purge gas vapors and test the gas vapor system for leak integrity. The canister purge solenoid (CPS), canister vent solenoid (CVS) and fuel tank pressure sensor (FTPS) are the heart of the system. P0446 FORD EVAP System Vent Control Circuit The Evaporative System (EVAP) canister vent control valve is located on the EVAP canister and is used to seal the canister vent. This solenoid valve responds to signals from the Engine Control Module (ECM). When the ECM sends an ON signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. P0455 FORD Evaporative Emission Control System Leak ... P0455 FORD Meaning 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. Ford Ranger P0456: EVAP System – Small Leak | Drivetrain ... The EVAP system captures all fuel vapor from the fuel tank and sends them to the engines intake in order to be ignited in the normal combustion process. When there is a small leak in the Ford Ranger’s EVAP system, it will throw the P0456 OBDII Code. P0455 Ford Evaporative Emission Control System Leak ... P0455 FORD Description. 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. P0442 FORD Evaporative Emission System Leak Detected ... P0442 Ford Description. The Engine Control Module (ECM) tests the Evaporative Emission (EVAP) system for the following conditions: Large and small leaks. Excess vacuum. Purge flow during non commanded conditions. Fuel Level and Fuel Pressure sensor faults. EVAP Purge and Vent Valve faults. Evaporative Emission Control (EVAP) System repairpal The evaporative emission control (EVAP) system captures gasoline fumes and other emissions produced when fuel evaporates within the gas tank or fuel system. The EVAP system then returns these vapors to the combustion process to keep harmful chemicals from reaching the air when the vehicle is not running. Symptoms of a Bad or Failing Canister Purge Solenoid ... The canister purge solenoid is an emissions control component that is commonly found on the evaporative emissions (EVAP) system of many modern vehicles. Modern vehicles are equipped with an (EVAP) system that works to reduce the evaporative emissions pollution that can come from the vehicle’s fuel, which is released in the form of vapors.
