What does it mean? | Check Engine Light Reasons

Seeing your check engine light turn on when you start your car can be frustrating and stressful as there are many reasons behind why it may be on. Sometimes, it’s a small issue. For example, a sensor may be malfunctioning or your gas cap may not be sealed properly. Other times, a more serious issue with your emissions system or motor may be triggering the light. The older the car, the more likely parts are to malfunction over time, so it is important to keep up with regular maintenance and repairs in accordance to your vehicles recommended servicing timeline outlined in your user's manual. Here are some of the most common reasons your check engine light comes on:

  • Gas cap is loose or missing
  • O2 (oxygen) sensor needs replacement
  • Spark plugs or plug wires need replacement
  • Catalytic Converter needs replacement
  • Mass Airflow Sensor needs replacement

How to Reset a Check Engine Light

When that bright indicator appears on your dashboard indicating there is something wrong with your car, it is recommended that you bring your car to a mechanic to diagnose and reset the fault code. It is easy to connect to an OBD (on-board diagnostics) scanner which will quickly run through your vehicles numerous sensors and read all the codes. This will give the mechanic valuable information and insights about your vehicle and what could possibly be triggering the warning light. At the best, it can be just a loose or faulty gas cap, but at the worst it could mean a full engine rebuild.

There are a few simple techniques that you could try yourself at home to try and get rid of the dreaded check engine light before taking your car to the mechanics. You could try to continue driving as normal to give your car's computer a chance to reboot. Another option is to turn your car on and off again a few times as you would do with any computer. Allow the car to be on for a few seconds, and then turn the car off for a few seconds. If the light still continues to remain on, try to disconnect and reconnect the battery to do a hard reset to the on-board system. If all else fails, bring your car to a repair shop where they can properly diagnose the issue(s). The mechanic has the ability to reset the system's diagnostics to rid the warning light from the dashboard, but that is only a temporary fix. In order to get rid of the light permanently you must determine the source of the issue(s), and replace the necessary parts. Once the necessary parts are fixed, you will need to reset your vehicles computer system and drive approximately 50-100 miles in order to reset your check engine light for good.

FAQs

Can I reset my own check engine light?

Yes, you are able to reset your own check engine light when it appears only if you have an OBD sensor that is able to connect to your vehicles on-board computer. Disconnecting your car's battery and reconnecting it can also reset the check engine light, but only temporarily.

How do I clear my check engine light without a scanner?

Without an OBD scanner, you will be unable to clear your check engine light. You have the option to disconnect the battery and reconnect it. This forces the car's computer system to do a hard reset meaning that the light will return. The only way to clear the fault code is to fix the issue directly.

How do I turn my engine light off?

Unfortunately, there is no way to manually turn off your check engine light unless you have an OBD sensor that can reset the car's on-board computer. You may be able to disconnect the battery, but that will only temporarily solve the issue. If your check engine light comes on it is recommended that you immediately take your vehicle to the mechanic to inspect and diagnose.

How long does engine light take to reset?

Typically, a check engine light will take around 50-100 miles in order to reset. Once a repair has been done and the fault code has been reset, restart your trip counter on your dashboard and continue to drive your vehicle until you reach approximately 50-100 miles. On average, a person would be able to drive this distance in a few days if not less.
