How does the EVAP canister purge volume control work?
The EVAP canister purge control volume control valve is operated by a step motor for control of flow rate of fuel vapor from EVAP canister. Each time the valve opens or closes to change the flow rate, an on pulse is issued. When no change in the flow rate is needed, the valve remains at a certain opening, hence no pulse signal output is issued.
Where does the fuel go in an EVAP canister?
Your EVAP canister can hold a high amount of fuel vapor when your vehicle is in good shape and operating at high efficiency. The fuel vapor goes into your engine to get burnt. This process is termed ‘purging,’ which needs to be assisted by the purge valve.
What are the symptoms of a bad EVAP canister?

What does the EVAP canister actually do?
A charcoal canister or EVAP is an essential part of a vehicle . Every vehicle has a fuel tank that emits a flammable gas vapor. When the vehicle is in action, the temperature will rise and its fuel will evaporate then become vapor.
