The canister purge solenoid valve is a container located inside the engine bay that houses fuel vapors to be recycled back into the combustion system when necessary. It is normally mounted on the firewall of the engine compartment.Continue Reading
The canister purge solenoid valve also serves as a diagnostics tool used to troubleshoot the emission system. The valve is able to be manually shut to test for leaks in the system.
The canister purge valve is difficult to diagnose since its failure can cause other sensors from the emission system to malfunction. When the charcoal inside the canister breaks apart, it may cause some pieces to jam the valve. Common symptoms of a malfunctioning canister purge solenoid include an erratic idle and illuminated check engine light.Learn more about Car Parts & Maintenance
The vehicle evaporative emission control system purge valve regulates how much fuel vapor the system purges from the charcoal canister that traps and stores the vapor. When the engine is running, sensors trigger the check engine light if the purge valve allows a vapor flow greater or less than normal.Full Answer >
The Evaporative Emission Control System (EVAP) keeps fuel vapors from leaking into the atmosphere by collecting and storing the vapors in a canister filled with carbon pellets. The carbon pellets collected by the EVAP system and temporarily stored in the canister are released back into the combustion process when the engine is turned on. The valve controls the airflow through the canister. Part of the valve is connected to the hose and has a filter at the end.Full Answer >
Sea Foam gas treatment is a gasoline additive that breaks down petroleum varnish, a byproduct of combustion that can cause deposits of soot and other contaminants throughout an engine and fuel system. Sea Foam helps break these deposits down while lubricating parts and reducing moisture buildup.Full Answer >
The fuel vent valve sits atop the fuel tank and vents vapors into the charcoal canister, which are then burned off in the combustion chamber as part of the normal operation of the vehicle. Normally functioning valves remove air from the fuel system as it tries to settle into the tank. These components can wear over time, leading to misfires, reduced fuel efficiency and increased emissions.Full Answer >
