Warning lights

[bcc101]

When driving to DC about a month ago, the check engine,VSC Trac,and VSC Off lights came on.
I had recently filled the fuel tank and being in a hurry because our van was not running well I had to switch cars. I did not tighten the filler cap properly.
A call to the dealer's service dept. led me to believe the problem would go away after a few starts.
The lights are still on.
I would appreciate any suggestions.
Thanks, Bruce

if u think it was only the cap, disconnect the - battery term. for 5min. that will rest the ecu, but u will then have to normalize the window , etc. if that does'nt turn the lights off or they come back on again, go to a parts store & see what if any codes come up.

If the battery trick doesn't work, search for zero point calibration. This may be required, luckily there is a writeup showing how to do it yourself (very easy).

I have this problem lately as well. I don't have the check engine light though. I did the zero point calibration today after work. The lights turned off for the first 2 minutes of driving and I thought it was fixed.... Then they came right back on. Does anyone have any clue what the cause of this could be. I have searched and cant seem to find anything that will fix the light problem.
