Last Updated on February 15, 2023 by Ryan

If your gas cap is not venting, it can cause a number of problems. The most common symptom is the check engine light coming on. This is because the pressure in the fuel system is not being released and the system is detecting a leak.

Other symptoms can include poor fuel economy and difficulty starting the engine. If you think your gas cap is not venting, take it to a mechanic to have it checked out.

If you notice that your gas cap is not venting properly, there are a few things that could be the culprit. First, check to see if the gas cap is loose or damaged. If it is, simply tightening or replacing it should do the trick.

If the gas cap appears to be in good condition, then the problem may lie with the vent valve itself. This can often become clogged with dirt and debris, preventing it from working properly. Cleaning or replacing the vent valve should take care of the issue.
