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.

How long is pesto good after it's been opened and refrigerated? Answer Wiki. I'm only half joking, but it depends on how hungry you are. From my experience, as long as it has a good coat of olive oil on the surface and you keep it sealed in the fridge it should last at least 3 - 4 months. Always better fresher, though!! We at times when making fresh pesto actually made ice cubes of pesto, froze them and then ziploc bagged them.
