Jeep: Gas Cap vs Chk Engine Light

Go to Auto Zone they will use a scan tool for free and can reset the check
engine light for you too. The largest cause of the check engine light is
the gas cap most of the time it will be a P0454 or P0455 a leak in the
emissions control system. Buy a new cap that Auto Zone it makes them feel
good after using the scan tool.

Is
