What is the Gas Cap all about?

The purpose of a Gas Cap is twofold: one, it helps prevent dust and other particles from getting into the gas tank, and two, it helps prevent fuel emissions from entering the atmosphere. If your gas cap is faulty, the Check Engine light may come on. Additionally, your vehicle may fail a smog test if the gas cap is gone or not functioning properly.

How it's done:

  • Inspect the gas cap.
  • Pressure-test the gas cap.
  • Install new gas cap if faulty.

What common symptoms indicate you may need to replace the Gas Cap?

  • Check Engine light is on.
  • Car does not pass the emission test.
  • Gas Cap is missing.
