Why is My Check Engine Light On?

Truck Repair in LynnwoodHaving your check engine light go off can be very stressful for any driver. We have put together a small list of common reasons why your light may have gone off:

  • Gas Cap Problems – Before you head to a mechanic to deal with a check engine light, make sure that your gas cap is secured. If you open up your fuel door and discover that you forgot to replace your cap before leaving the gas station, then that is most likely the reason your light went off. Once properly replaced, you may have to take your vehicle to a specialist to turn off the light.
  • Oxygen Sensor Issues – When you operate your vehicle, your exhaust releases gases, including oxygen. When the fuel mixture either has too little or too much oxygen in it, there may be a problem with your engine. Most vehicles have an oxygen sensor that will set off the check engine light.
  • Spark Plugs Need to Be Replaced – The spark plugs in your vehicle help ensure that it is running correctly by igniting the air and fuel mixture in the engine’s combustion chamber. If they are not working adequately, it can cause poor vehicle performance and eventually set off your check engine light.
