How Can I Reset the Check Engine Line?
How can I reset the check engine light? First off, be aware that this light doesn’t come on on some mysterious whim of your engine. It means that there is a problem somewhere. Resetting the light itself isn’t the best idea until you know what is behind it being on in the first place.
As your auto repair shop we don’t recommend resetting the check engine light. You want to have a mechanic do that in the best way he can, by fixing the root problem behind the check engine light. Resetting the check engine light by unplugging the battery will also wipe out all of the data in the computer and merely pause the check engine light, not reset it permanently. Then you will have the double whammy of having the check engine light on and no data as to why.
CAN YOU JUST IGNORE THE CHECK ENGINE LIGHT
Can you just ignore the check engine light? Again, that depends on what the underlying cause of the light is. If your mechanic has told you what the cause is, he can reset the light so that it won’t trip and turn on, but you will still have the problem that caused it in the first place. This is kind of like putting a band aid on a cut after it’s been infected. And we get it. The light is an annoying feature. It never gives you enough information to be useful and adds a bit of stress to your day.
So remember, a check engine light can mean a lot of different things. Until you know exactly what it means, don’t worry too much. Just get your car or truck into an auto mechanic as soon as you possibly can.
