Repair the source, light will go out if that was the only problem. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active. Disconnecting the battery can create other headaches and will not likely solve your dilemma. Best bet is to contact the local snap-on dealer and have him refer you to a known good shop that specializes in this technology-he will know. The " check engine light" is by far one of the most misunderstood technological advances by the public. This is an needed in-depth understanding for the public. It is a warning light that is illuminated when there is a problem affecting the EMISSION SYSTEM only. Emission system being the pollution control system. Don't get a hard on against it as it is a good thing once you understand it. One point that was brought up a 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 that about 7% 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 17 different computers) will run a series of self-tests. They will only run under certain criteria. And they can be vastly different from manufacturer to manufacturer. Some self-tests are not run until preceding ones have run successfully. So if there is a problem in one particular area that is preventing another self test from running, you can have a situation where one problem is fixed, but another still exists. If you fix a problem and drive the car through a drive cycle that sets the monitor (or self test) the light will go off as it passes that criteria that triggered it in the first place. After 1996, the auto industry went to a idea called OBD II (on board diagnostics). This was to get all the manufacturers onto a similar plane for troubleshooting and powertrain control. While they still differ vastly, many corrections and adaptations were made for technicians to better fix the check engine light problems. Prior to this there were so many different and poor troubleshooting data from a check engine light problem that resolving the problem was much more difficult. Many early warning light of this nature were set to illuminate based on mileage. An Oxygen sensor was one of the things that were meant to be replaced when that mileage was hit. This is much like many current "Change oil lights
No, resetting the light will not fix the cause of the problem.
Check engine light or required maintenance light. Procedure for resetting required maintenance light just answered. Check engine light requires an OBD II to determine problem and turn the light off.
Resetting the ECM without fixing the reason why the check engine light came on will only lead to the check engine light coming back on soon.
The best way to turn off the check engine light on a 91 Mercedes 300 SE is to disconnect the battery. However, resetting the light this way will not fix what made the light come on.
check engine usually is emissions related, try resetting by disconnect negative battery terminal for about 5-10 minutes.
disconnect battery cables and touch them together! I have done this and it worked. I have an 05 2500hd
First you need to determine why the check engine light came on then make appropriate repairs before resetting the check engine light. Take a drive to your local auto parts store and have them check for codes. They will perform this service at no cost to you. Once you have the codes you or your mechanic can determine what the next step should be.

If your engine management light comes on, there may be a problem with your vehicle. The only way for the light to be removed is by resetting the light. The light needs to be reset by someone with a resetting tool. This is generally your local mechanic.
Try resetting the fuel cut off switch and see if the engine will start
It has to be done with a scan tool. Resetting the light without correcting the problem will be of no use as the light will come back on.
unhook the battery for about 2mi. that well resetthe elecrical If you are taking about resetting the check engine light, then you will need an OBD2 scan tool. Removing the battery cable will not reset the check engine light.
The check engine light is on because the engine control module (ECM) senses a problem with the system. Resetting the check engine light without making repairs will only set the light back on again. Drive to your local auto parts store and have them read the codes that are set and with that information they can help you determine what needs to be done to cancel the check engine light. It would help to also list the year, make and model vehicle you have for us to help you.
Depends on which engine warning light you are referring to. If you are referring to the Check Engine light then have the problem repaired that caused it to come on in the first place. They will reset the light. Resetting the light without repairing the problem and it will just come back on.
Resetting an engine light on a 1996 Dodge Caravan SE is very easy to do. The battery can be disconnected for up to one minute to make the check engine light go off.
Have the problem repaired and they will reset the light. Resetting the light without repairing the problem and it will just come back on. You reset it with an OBD2 scan tool.
No sorry. you gotta pull the whole instrument panel out to get to it.
The easy fix to reset the "check engine" light on the Jetta is to completely unhook the battery for at least 10 minutes. This may possibly be only a temporary fix though if the original problem that caused the light to come on still exists.
With an OBD2 scan tool. Resetting the light will do no good unless you repair the problem that triggered the light in the first place. It will just come back on.
No, oil level does not cause the check engine light.
The service engine light is the same thing as a check engine light.
First, a check engine light usually means that the computer has stored an error code. Find out what is wrong and repair the problem. Once that is resolved, the owners manual has instructions for resetting the check engine light. The procedure is different for most vehicle manufacturers but it is usually quite simple if you follow the directions in the book. Have vehicle scanned to determine the problem
