Question about 2002 Jeep Grand Cherokee
Periodically the service engine light soon come on with my 2002 Jeep Grand Cherokee when the gas tank is over 1/4 full. After the tank goes down the light goes off.
A loose gas cap will sometimes trigger the service light to come on. Since this appears to have happened on multiple occasions I can assume that this is not the problem but may be associated with it. The level of gas in the tank affects the amount of atmospheric pressure in the tank. There are multiple things that could set off the light, one being a loose or defective gas cap, and the other is a fuel vapor return valve. I'm not sure of the exact type of fuel system you have so I cant give a more exact answer. If you wanted to give something a shot before bringing it into the shop, you can simply replace the gas cap first, a very cheap try.
