So what is a canister purge solenoid, and how is it related to these potentially destructive vapors? Well, with all these limitations in mind, manufacturers install an EVAP system to collect and store the vapors in a canister purge solenoid until the engine is started again and they can be released and burned through normal combustion.

The canister operates via either a vacuum or electricity and is filled with charcoal, which traps the vapors. Most modern vehicles have electronic canister purge solenoids controlled by the engine control unit, or ECU. After the car is started, the computer waits for the engine to reach operating temperature, then sends a signal to the solenoid on top of the canister to open the valve, letting the stored vapors into the combustion system.

If this happens, you may notice a few telltale signs. For one, your check engine light will illuminate. A stuck-open valve creates a vacuum leak that allows too much air to enter the engine, throwing off the air-fuel ratio and causing a noticeably rough idle or hard start. Like many automotive parts, dust and dirt can clog the canister. The purge valve can even crack from harsh conditions in the environment.
