Not sure when it came up, my wife drives the car. She said it came up the day after she put gas

Check the cap for looseness. If that's not it. you will need to check for any cracked vacumm lines, a bad cap, or a leak in the eveporative emissions system.


This code is when the system sees a leak when self testing after it has seen a change in the fuel level sender voltage. So naturally it assumes a loose fuel cap.
