The check engine light will come on and set a code if the fuel system isn't sealed air tight. On some automobiles it is known as the P0440 code. I also wanted to talk more about the evaporation emissions system that can set other diagnostic trouble codes in the P0400 range.
Technically in the sausage family, hot dogs can be kept in the refrigerator for up to two weeks unopened or for seven days in the refrigerator after opening. In the freezer the time is one to two months.
Other sources say that you can keep the fresh cooked sausage in the refrigerator up to seven days if kept at 40 degrees F (which is the normal setting in both restaurant and home refrigerators). Another says up to five days for cooked Italian sausage, lightly smoked sausage, or breakfast sausage.
