My 2001 cherokee is showing the check engine light. I can have it reset and I can drive around the world and back without it going off again until I hit a bump pretty hard and BING, there it is again. The dude at Advanced. Auto Zone...or wherever I went, said it was probably the gas cap was lose or I got gas with the engine still running. WHAT? Anyway, I have ensured I cut the thing off when I get gas and I turn the cap about ten times when I put it back on and the light still pops up. I carried it ot a couple of other parts stores and had them scan it just to see if I got something different and they all said "gas cap" right off the bat. Can my gas cap just be "bad"? Should I replace it? Also, what other issues could be throwing that same code. The jeep is running fine and I cant tell any difference anywhere with the light on or off so I dont think it's a critical issue but I would like to get the light off and keep it off.

Thanks in advance.....

I would think a gas cap would be cheap enough to give it a try and not worry or stress about it.

Buy a gas cap at one of these autoparts stores you frequent and if it don't work march right back in there an tell them you want a refund. I mean it is a crappy thing to do but you can do it. Tell them there scanner is broke lol.

just an fyi, 01 jeeps use a pre-vented gas cap.
those small ones at auto part stores are only vented.

i had to get mine for the tj at the dealer. 45 bux.

UPDATE: Got a new gas cap....just tried one from the parts store and had them reset the check engine light.....no more issues. It seems to have solved it. Thanks
