Q: What is the purpose of the Evaporative Emissions Control (EVAP) system and Vapor Canister on 2000-2011 Ford Ranger?
A: The Evaporative Emissions Control (EVAP) system prevents fuel vapors from escaping into the atmosphere. On warm days, these vapors expand and are routed to the EVAP canister for temporary storage. The Powertrain Control Module (PCM) then allows these vapors to be drawn into the engine. The EVAP canister, located under the vehicle, contains activated charcoal and requires no maintenance. Other key components include the fuel tank pressure sensor, fuel vapor vent valve, and canister vent solenoid. Symptoms of a faulty EVAP system include a strong fuel smell and poor driveability. Diagnosis and repair should be done with an OBD-11 scan tool and by a qualified repair shop. Component replacement involves detaching vacuum lines and replacing the canister.
Q: What is the purpose of the Evaporative Emissions Control (EVAP) system and Canister on 1993-2011 Ford Ranger?
A: To begin with, the EVAP system is responsible for keeping the fuel vapor from escaping into the atmosphere. Some of the parts of the system include the EVAP canister, fuel tank pressure sensor, fuel vapor vent valve, canister vent solenoid, fuel filler pipe check valve, canister purge valve and EVAP dust separator. The canister stores fuel vapors while the pressure sensor monitors tank pressure. The vent valve prevents overfilling and solenoid controls vapor flow. The check valve blocks fuel escape during refuelings. The purge valve regulates vapour flow to intake manifold. Dust separator prevents entry of particles into the system. Common symptoms include poor engine performance and gas smells in particular cases concerning EVAP faults. Inspection and component replacement may be necessary after a professional diagnosis using an OBD-II scan tool.
