Question about 2003 Chevrolet Silverado 1500
There is air escaping from the gas tank. Often a problem with the gas
cap, try tightening the cap, reset the code and see if it comes back
on. Essentially it is testing for cracks in the tank.
Also remember just because there was a condition that activated the sensor does not mean it still exists. Have the codes reset. If it comes back it may be a bad seal on the gas cap. But just incase keep an eye out for possible leaks.
Auto Zone can read codes they may also be able to reset them. If not try disconnecting the battery for 10 minutes to see if that will reset the codes
Hope this helps.
