It will probably throw a CEL if you disconnected it.

Some venting of the gas tank must be provided so it can "breathe" during temperature changes and when the engine is running, so this is provided by hoses connected to a charcoal filled canister usually located in the engine compartment. The charcoal particles in the canister soak up and store fuel vapors when the engine is not running. Then, when the engine is started, a "purge valve" opens to siphon the vapors into the engine where they are burned.

It might not throw a CEL immediately, but it will eventually.

if it allows the gas tank to breathe, then why does mine go "thhhewwwpptt" every time i unscrew my gas cap? does it only let out postive pressure and not allow air into the tank?
