What Could Make The Light Turn on?

There are actually quite a few reasons why your check engine light can turn on. One of which doesn’t necessarily have to do with your engine at all! Let’s take a look at the most common problems that can make your vehicle’s check engine light come on:

  • Gas Cap Loose/Missing/Broken:This is the one reason that really has nothing to do with your engine directly. If your gas cap isn’t properly tightened or if it was lost or damaged, it can cause your check engine light to come on. It’s extremely important to make sure your cap is screwed on tightly after getting gas and to make sure it isn’t damaged. If it isn’t fixed you can end up losing more fuel via evaporation and end up having to get gas far more often.
  • Time to Replace the Mass Airflow Sensor: The mass airflow sensor for your vehicle measures how much air enters the engine to determine how much fuel the engine needs to run at it’s most efficient level. It’s important to get this part checked and replaced because it can lead to damage for other parts of your engine and lead to reduced performance and reduced fuel economy for your car.
  • Check Engine Light PortlandSpark Plugs or Plug Wires: Your car’s spark plugs a crucial part to your engine’s ignition system. If the wires or plugs themselves are corroded or worn, you can experience poor power performance, reduced fuel economy, and can cause issues to other key components of your engine.
  • Bad Catalytic Converter: Catalytic converters are important for your vehicle’s exhaust system, as they convert carbon monoxide into carbon dioxide. When the converter starts faltering, you could be causing harmful carbon monoxide to be put into the air. If you have a bad converter, it will cause your vehicle to fail emissions tests, hurt your car’s fuel economy, and can even make your car run at a higher temperature, leading to it potentially overheating.
  • Poor Oxygen Sensor: The oxygen sensor of your vehicle measures the amount of oxygen that needs to be burned in the exhaust system. If the sensor is failing and needs replacements, the engine will burn extra fuel which results in less miles per gallon. It can cause damage to other parts of the engine, including the spark plugs.
