The Evaporative Emission (EVAP) System is designed to prevent fuel vapor from escaping into the atmosphere. An "Evap System Small Leak" diagnostic trouble code (DTC) is generated when the engine control module (ECM) detects a small leak in the EVAP system.
Common causes of an Evap System Small Leak include:
It is important to have the vehicle inspected and repaired by a professional mechanic as soon as possible to avoid further damage to the EVAP system and potential safety hazards while driving. An Evap System Small Leak can also result in decreased fuel efficiency and increased emissions.

Hello there.
The PCM conducts vacuum or pressure tests on the fuel vapor and tank system, looking for the presence of leaks, either large (gross) or small, that could allow vapors to escape into the air.
Although an EVAP system leak will result in your check engine light turning on, it won't instantly impair your ability to drive. However, as you travel, you are allowing dangerous gasoline vapors to escape into the air and contribute to the greenhouse effect that is associated with global warming. Fixing the problem is often as simple as having and tightening the gas cap.
