If you’re wondering how to reset the check engine light, and you’re either sure that there is nothing wrong or you have chosen not to fix the issue right now, this guide will help you. While it’s up to you to fix the issue, it’s highly recommended that you have any problems taken care of right away to avoid any further issues down the road.

Reset the Check Engine Light Steps

If there are no issues, you can manually reset your check engine light. For drivers who are not super familiar with what’s under the hood of their vehicle, this may seem like a daunting task – but it’s not! Just follow these steps:

  1. Turn off the ignition and put on safety glasses and gloves
  2. Locate the negative terminal. Usually, it has a black cap and a negative (–) symbol. For reference, the positive cap 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 30 – 60 seconds.
  4. Reconnect the negative cable and tighten it back up with your wrench.
