Help with engine code 0456 - EVAP VERY SML LEAK
I recently got a 2004 Sentra 1.8S. This last week or so, my Check Engine Light has been on. When I pull the code, I get 0456, which is EVAP VERY SML LEAK.
I have been unable to identify what is causing this problem.
The first thing I checked it the gas cap, and it is on securely. Inspecting the vacuum system visually as best I could, I saw nothing wrong either.
After I reset the code, while driving, if I release the accelerator just a little bit while cruising, the engine light lights up, but does not stay on. I can easily recreate this situation at any time. After restarting the car, the engine light stays solid until I reset it again.
Any information on what can cause this problem would be appreciated.
