I had a 1999 Saturn SL2 and my husband took both the battery cables off and then replaced them. This caused the check engine soon light to go off. == other answer== Depending on what triggered the light to go on, you could fix it, and the light has a chance to go out on it's own (I have had mine come on 4 times , 2 of which I have had to reset with a diagnostic computer from a local parts place, once it went out on it's own [bad spark plug] and THIS time it's still on) the answer above is correct only to the point of the next self-diagnostic check from the car, if something is still wrong, the light will come back on The " check engine light" is by far one of the most misunderstood technological advances It is a warning light that is illuminated when there is a problem affecting the EMISSIONS of the vehicle.. Don't let it bother you as it is a good thing once you understand it. One point that was brought up a recent meeting of technicians was that the amount of hydrocarbons is greater when the gas cap is left off than when the engine is running. Hydrocarbons are part of pollution emitted as gasoline evaporates. Going a step farther, one facet of the emission system is the "Evaporative" portion. This is when the fumes from the gasoline are leaking from the system into the outside air. This is one part of the emission system that can trigger a check engine light. I would say a small percentage of the vehicles that have a check engine light are the result of a loose or inadequate gas cap. But understand that many scenarios are possible with the "check engine light" The vehicle's powertrain computer (note that some vehicles have multiple computers aside from the powertain computer) will run a series of self-tests. They will only run under certain criteria. And they are different from manufacturer to manufacturer. Some self-tests or
Most any code reader that plugs into diagnostic port can reset

disconnect neg and pos of battery for 1 minute
