If Your Check Engine Light Comes On, Head to Beaver Toyota of Cumming, GA for Diagnosis

Your Toyota has a variety of dashboard warning lights that will let you know if something is not working just as it should be. The Check Engine Light, also known as the Malfunction Indicator Lamp, is one of the best-known of these. It means that your vehicle’s computer (ECU) has detected a problem either in the engine or in one of the surrounding systems. If this engine-shaped light turns on while you drive, schedule an appointment at Beaver Toyota of Cumming as soon as you can. We provide exceptional Toyota service to drivers in Sugar Hill, Alpharetta, and beyond at the Beaver Toyota of Cumming service department.

Potential Causes of the Check Engine Light Turning On

One of the more frustrating aspects of the Check Engine Light is that it can be turned on by so many different problems, and finding the specific issue requires the use of a code reader that will interpret your vehicle’s OBD-II code. You can find some of the more common problems on this list, but there are many more.

  • Misfiring engine. Since this problem can cause catalytic converter damage, it will usually trigger a flashing Check Engine Light. Seeing this flashing light means you should pull over and turn off the engine as soon as you can.
  • A faulty mass airflow sensor.
  • Bad fuel injectors.
  • Failing fuel injectors.
  • A loose, missing, or cracked gas cap. It’s always best to check and make sure your gas cap is screwed on tightly when the Check Engine Light comes on.
  • Old spark plugs.
  • Bad O2 sensors.

The Benefits of Professional Check Engine Light Diagnosis

You can find places that sell OBD-II code readers; you may even know someone who owns one. However, it’s much better to have your Check Engine Light diagnosed by a professional, like the expert technicians at Beaver Toyota of Cumming. As part of our diagnostic service, our technicians will do more than just simply read the code: they will also perform an inspection of the part or system that the code indicates. They will then let you know their findings and their recommendation for repairs.
