Welcome. This code is a EVAP system performance code and is almost always set because of a loose gas cap or failed gas cap.
i tightened the gas cap, the engine light is still on, does it take a while to go off?
The test will have to pass the next test to turn the light off or use the code reader to turn the light off.
