If the car has run for a considerably long time, say 50,000 miles with the same gas cap, it’s safe to say that the reason is your gas cap is old, weary and exhausted. It will let pollutants find their way to your fuel chamber, clogging the filter.

Why is the gas cap missing from my Check Engine light?

The cap is not in place or securely sited. The cap is completely disappeared or missing from the car. The cap cannot close properly due to grime and mud near the opening. The gas tank is out of shape due to an accident, putting extra pressure on the gas cap.
