The purge valve controls fuel vapor flow from the charcoal canister into the engine. A bad one causes EVAP codes, rough idle, or hard starts after fueling.

Common questions
What symptoms does a bad purge valve cause?
Hard starts after fueling, a rough idle, and an EVAP code are common. The valve may stick open and let fuel vapor into the engine at the wrong time.
Is the repair cheap?
Usually. The valve costs $25 to $100 and often sits on top of the engine, so labor is short. Costs go up if it is hidden under other parts.
Will it pass an emissions test?
Once the code is fixed and cleared, the car must complete its self-checks before a test. That can take several days of normal driving.
