How do I know if my gas cap needs replacing?

The Check Engine Light Comes On Another symptom of a failing gas cap is the illumination of the check engine light.

A gas cap that cannot seal can cause an EVAP system leak.

How do I know if my gas cap is leaking?

To fix, expose the gas cap by opening the tank cover which is next to the compact box. If the gas cap appears tight, take it out and examine the seal that laps firmly to the cap. If the seal is broken, it won’t sit firmly on the gas cap, allowing gas to leak out. You should get a replacement gas cap seal.
