Check Engine Light Flashing

Check engine lights can come in yellow or orange, and it may appear solid or flashing on your dashboard when lit. The light is a signal that’s been generated from your car’s engine computer, and it means something is not working properly and your vehicle needs to be checked

Reasons a Check Engine Light is On

There are a variety of reasons a check engine light can be triggered, from the simple to the more complicated. Either way, you definitely don’t want to ignore this warning sign as it could indicate a major problem. Some top reasons a check engine can be activated include:

  • Loose gas cap: The first thing you should do is try tightening your gas cap. Sometimes it’s just that simple.
  • Emissions system: A solid check engine light often indicates that something is going on with your oxygen sensor, which keeps the air-fuel mixture adjusted properly for efficient gas mileage. You could also be having a problem with the mass airflow sensor, which monitors how much air is mixed into the fuel injection system.
  • Catalytic converter: This is a fairly expensive repair. This is also one of the reasons you don’t want to ignore a check engine light because catalytic converter issues can cause extensive damage to your engine.
  • Spark plug wires: This is another simple fix.
