Why Did My Check Engine Light Blink?

  1. The following are the most typical causes of a flashing or blinking check engine light: misfiring on one or more cylinders (the most common)
  2. Faulty spark plugs/Coils
  3. Engine sensors (coolant temperature, air temperature, exhaust temperature sensor, and so on) that are not working properly
  4. EGR valve that is not working properly
  5. Injectors that are faulty or defective
  6. Crankshaft/camshaft sensor that is not working properly
  7. Problems with exhaust emissions
  8. Boosting and overcharging issues
  9. Internal engine failure (this is extremely unusual)
  10. EVAP diagnostic problem codes
