Check Gas Cap

My check gas cap keeps coming on. I replaced my gas cap with a cap from the dealer but the check gas cap keeps coming on. It'* causing my service engine soon light to come on and I hate it. Does anyone have any suggestions as to what the problem might be. Please help.

Are you sure it'* on all the way? Turn it until it clicks. Otherwise the gas cap door might not be getting closed securely. This was a problem on my mom'* Transport.

That cap needs to be on tight for the tank to pressurize correctly. I'm not entirely sure how this works, but it'* an emissions problem, not a mechanical thing. I'm wondering if one of the vacuum lines to the vapor recovery tank is disconnected?
