    Just had a dealer tell me that our check engine light was caused by a gas
    cap not adequately tightened. After paying a pretty hefty service fee (we
    have always tightened the cap 10 - 20 clicks) it has happened again. Has
    anyone else had this problem? If so, what did you do, and was it covered
    under warranty?

    It can sometimes be a little bit of crud caught in the purge solenoid.
    There are dozens of causes for check engine light to appear. Some are
    trivial, like a loose gas cap, some are more important. Many Hondas
    have a simple way of reading the fault code
    I don't know if yours does or not. Some dealer charges for pulling a
    code are highway robbery, especially when the standard procedure is to
    reset the ECU and wait to see if it recurs before doing anything.

  3. If you are clicking it 10 times and you are still turning on the
    light, then that ain't it. (One or two clicks is all that's needed.)
    Either the cap is defective or there is a leak somewhere else. Either
    way, it should be covered under the extended emissions warranty if it
    hasn't expired - not sure if it was 50 or 100K in 2000.

    what was the code they gave you?

    i thought that mighta been the case with my 98 civic, but once i bought
    a code reader, i found out it was an oxygen sensor. it was lazy at
    first, then just went titsup.

    Will 'topping up' set that code when the evap canister gets pumped full
    of liquid gas?

    Are you 'topping up'?

    No. In fact the light came back on a couple of days later on the same tank
    of gas, at about 1/2 tank full

    This is an emissions issue, and they will fix (new cap) free. Happened to
    me. Once light starts comign on, it will contunue, even if reset.
    Usually takes a few engine cycles before light comes on.

    What kind of code reader did you get, cost?? Can it reset the check engine
