Hi, I took a chance on a locking gas cap for a 2000/2001 Jeep on my 2002?
Check engine light came on at half tank. Maybe I didn't get it tight enough, or they changed the cap? Anyway, Anyone have any problem with locking gas caps? Also, is there a way to turn off or check the check engine light with going to the dealer.
Thanks, Craig
Locking gas caps are common causes of Check Engine lights because they're often not air-tight enough to prevent a vapor leak in the fuel system that the computer will detect. Disconnect your battery for 2 minutes to clear the light.

Put the right cap on.
I think the '02 might use a different cap then the previous years. My '02 TJ has a factory cap that is a quick release design, that only requires about
1/4 turn to release, then it pops right off. I think the pre-'02 models used a different kind of cap.The correct locking cap should be available at your dealer, and should not be too expensive.
