the check engine light came on and later followed by gascap light. have changed gascap but cant seem to be able to reset, since i dont have a manual since my 07 caravan was bought used.
cdelasancha18, it should normally reset itself if you have driven it a few times after you replaced the gas cap. It is possibly that you have other issues. Take it to a place like Autozone, or anyone else, that offers a free quick scan and see what codes you get. It is possible that you have trouble with your ESIM valve, or even your oxygen sensor. You can, of course, try a reset by removing the negative (-) cable from your battery and leaving it off for a while. Hope this helps, good luck.
