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.
Use right away or freeze. Vacuum-packaged sausage can be frozen as is. Other items should be wrapped well to prevent freezer burn. Try to eliminate air from the package whether wrapping in zipper bags, freezer paper, or plastic wrap. You can freeze items for 1-2 months without affecting the flavor and quality of the sausage. Sausage frozen for more than 2 months will gradually undergo a loss of flavor and quality.
