Question about 2003 Jeep Grand Cherokee
That code is for a large evap leak.
that system is how the gas tank vents itself so the vapor/fumes don't go into the air.
most common cause is refilling while the truck is running and the second most common is a bad gas cap.
now if you go to auto zone and get it cleared and while you are there buy a new gas cap. and the code comes back on after you did that then you will have to find the leak and will involve some intencive trouble shooting.
if you have any ore question please ask.
