Service Engine Light

I have a 2002 Saturn L100 with 25000 Klms on it. Ileft the gas cap off for
250 Klms and the engine service light came on. I replaced the gas cap and
the light will not go off . What will turn it off.

If that's the only reason that the light came on, enough on-off cycles
without the problem should do it. Not sure what that number is for your
car.

either that or you can take it in to have the the SES light reset.

Disconnect the battery terminal {+} for a minute, then put it back on. This
will reset the SES light.
Quickest way to do it.

 

I agree this should do a reset, but this may cause additional issues such as
requiring reset of the security code in the radio, loss of pre-set stations,
etc. It also may run and shift rough till the computer re-learns the
appropriate settings.

Thanks to all. I disconnected the battery cable for a few minutes and then
reconnected it, started the car and the light was off. I had to reset my
radio stations.

 

From what I've heard, Saturns (unlike many other manufacturers) will self
reset the check engine light afer several engine run cycles. It may take a
week though.
Rather than pull the battery cable, I found on my '01 lw300, I can pull the
'controls B+' fuse for 20 seconds and reset the sevice lamp. This does not
loose the radio presets.
