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.
We recommend leaving sausage in vacuum packages until used to prolong shelf life. After opening a vacuum package, remove the remainder of the package. Rewrap sausage tightly to keep air out. If sausage is moist, wipe dry before repackaging.
