Learn How to Reset a Check Engine Light

Check Engine Warning Light

 

Before we dive too far into this subject, it should be noted that a trained automotive service expert, like those at our Service Center, should be consulted before attempting to reset or potentially ignore a check engine light. 99% of the time, if a check engine light has come on, it’s because there is a persisting issue with your vehicle’s powertrain that should be addressed immediately. On the rare chance that your vehicle isn’t actually having an issue, it would be worth knowing how to reset a check engine light on your own. So the very same team here at Dave Arbogast Buick GMC is here to help you learn how to do just that. Keep reading for more info! Be sure to contact us online if you have any questions, or would like assistance with your Sidney area vehicle’s check engine light!

 

 

If There is a Problem, Have it Resolved

If you’ve arrived at the conclusion that you’re going to reset your check engine light, you’ve either hopefully resolved whatever issue was originally causing the light, or are choosing not to have it addressed right now. While this is ultimately up to you, we of course urge you to take care of the issue as soon as possible, not just as a business who repairs vehicles, but as neighbors who care about the safety of our fellow Springfield area residents. Not to mention the fact that ignoring a small mechanical issue can snowball into having to repair something much more expensive.

Check Your Gas Cap!

One cause for a check engine light that many people don’t know about is a loose or cracked gas cap, which releases fumes into the air. Next time you’re safely parked, remove your gas cap, make sure the threads inside are clean and free of dirt or debris, and firmly secure the cap back on. If the check engine light doesn’t turn off right away after doing this, follow the steps below to disconnect your battery, which should in turn reset the light.

Simply Disconnect the Negative Battery Cable

If you’re sure that resetting your check engine light is the proper next step, manually resetting your check engine light via removal of the negative battery cable is going to be your best bet. Simply follow these instructions:

  1. Turn off the ignition and put on safety glasses and gloves for protection.
  2. Locate the negative terminal on your vehicle’s battery. Typically it’ll have a black cap and a negative (–) symbol. The positive cap, on the other side, is red and will have a positive (+) symbol.
  3. Loosen the nut on the negative terminal with a wrench, then pull the negative connector from the battery. Keep it to the side for roughly 30 – 60 seconds to give the computer a moment to reset.
  4. Reconnect the negative cable and tighten it back up with your wrench.

This should do the trick and have you back on the roads of Dayton in a jif! However, if it doesn’t, we’ve got another option for you to try. Please note that disconnecting your battery will also reset your vehicle’s radio or infotainment system!
