Check Engine Light Flashing
The check engine light is usually yellow or orange, and it can be solid or flashing on your dashboard. The light is a signal that’s been generated from your car’s engine computer, and it means something is not working properly. So if the check engine light is lit, something is definitely up.
Why is My Check Engine Light On?
Well, the good news is that all automotive manufacturers use a standardized system of codes, so it’s going to be pretty simple for a mechanic to assess the problem. The source of your malfunction may be minor and inexpensive, but it can also be something more serious:
- 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, and you don’t want to wait see if it’s the problem because it can cause extensive damage to your engine.
- Spark plug wires – This is another simple fix.
Do it Yourself or Consult the Experts?
You can actually purchase a device that reads the manufacturer problem codes. These code readers are not expensive, and they plug into your vehicle’s OBD-II port for standardized onboard diagnostics, usually under the steering column. You check the code and use the Internet to diagnose the issue. Most people are not inclined to do this on their own, especially since you’ll probably need a mechanic to fix the problem in the end.
