2020 VW Passat interior

If your check engine light pops on while driving on the Dallas roads, don’t panic. In some cases, you may determine that there’s nothing actually wrong with your engine. However, sometimes the light remains illuminated after the problem is resolved. If you are wondering how to successfully reset a check engine light, the service experts at Principle Volkswagen have you covered.

Address the Problem First

If you’ve reached the point where you’re wondering how you can reset a check engine light, you have determined that the issue is not a cause of concern, or you’ve decided not to fix it right now. While it is up to you whether you decide to have the problem fixed by a professional, we highly recommend that you bring your vehicle in for service as soon as possible. We want to ensure you are driving safely on the roads of DFW. Plus, a small issue with your vehicle could turn into a more serious problem over time. We make it easy to set up your next service appointment online.

Disconnect the Negative Battery Cable

If it has been determined that there is nothing wrong with your vehicle, you can try manually resetting your check engine light. If you do not do a lot of DIY vehicle maintenance, this may sound like a challenging task. Fortunately, it only takes a few minutes. Simply follow the steps listed below:

  1. Put on safety glasses and gloves, then turn off the ignition.
  2. Find the negative terminal on the battery. On most batteries, you will see a black cap and a negative (–) symbol. The positive terminal usually has a red cap and a positive (+) symbol.
  3. Use a wrench to loosen the nut on the negative terminal. Take the negative connector off of the battery. Set it to the side for 30 seconds to one minute.
  4. Reconnect the negative cable and use the wrench to tighten it again.

Before you do this, keep in mind that disconnecting the battery could reset your vehicle’s infotainment system.

Check Your Gas Cap

If your check engine light is on, the issue could be as simple as a loose gas cap. If your gas cap is loose or cracked, fumes can be released, causing the check engine light to illuminate. If this happens while you are on the roads of North Texas, pull over when you can safely park and remove your gas cap and put it right back on. This could fix the issue. If it does not, try the steps for disconnecting the battery that are listed above.
