No. The check engine light indicates a problem, and I guarantee that it will return, eventually. If it is on a continuously monitored system, meaning the PCM watches it at all times for failure, the light will come on immediately. Sometimes it deals with a system that runs a monitor that is supposed to occur only once on a drive cycle, but may not run for days, weeks or even months. An example of this would be an EVAP fault. There are actually instances where this does not ever run, especially if you live in a very high altitude. There are also many, many failures that have absolutely nothing to do with a sensor. For instance, there can be a vacuum leak from an intake manifold, and the repair for this would be to replace the gasket, most likely. Also, the vehicle CANNOT be diagnosed off of the code, so don't waste money by throwing parts at a vehicle based on an unqualified person's diagnosis. For instance, you may see an oxygen sensor code and decide to the replace the sensor. What if there is a short circuit in the wire? What if the sensing circuit in the PCM is faulty? What if the reference voltage circuit isn't present? What if there is electrical noise close to the wiring from the secondary ignition system due to a faulty plug wire? If any of these are the cases, the sensor replacement will fail to correct the problem and the light will return, probably in just a few minutes. For this reason, I strongly recommend taking the vehicle to a professional repair facility that is an ASE Blue Seal certified facility by the National Institute for Automotive Service Excellence. This certification is given to 3-4% of all the facilities in the nation, and you may be surprised to know that very, very, very few dealerships have it.

yes---you can disconnect the battery for about 5 minutes ( only 1-2 is really needed, the extra is for good measure) then reconnect and the engine light will be off. it may not come back on and then again it me turn on in 5 minutes or five days. although this is not recommended. if your check engine light is on then you should get checked out. there could be something seriously wrong and ignoring it could be costly.

Until the problem is repaired,the light will continue to set.Why not have someone check the trouble code being generated and see about fixing the problem? It may be as simple as tightening the gas cap.Also the gas mileage and performance will suffer if the computer doesn't have enough information and is forced to guess at how to feed in the gas.

For some cars at least, disconnect the battery for about five minutes. Then reconnect. The light will come back on later if the problem wasn't corrected.

Depends on the make. For example, Hondas require that you hold in the reset and select keys simultaneously and then turn ignition to on. Hold ten seconds and light goes out. Your owners manual may have instructions under "maintenance".

you should only have to unhook the battery cable for about 30 seconds and it should reset itself.

go to autozone and they will scan it for free and can clear it for you.
