What is the role of my Kia Sedona glow plug light?

The main intent of the engine glow plug light, which is most of the time represented by a yellow coil, is to ensure that your glow plugs are working effectively. Indeed, it must light up when you switch on your Kia Sedona to tell you that they are heating the intake air in your cylinders and must go out after a few moments when the engine is running. This preheat light is therefore not meant to stay or come on while driving with your car. However, if it turns on while driving, it may suggest multiple troubles, we will try to summarize the most important ones.

  • Issue of EGR valve, indeed, if you suffer a loss of power, it is possible that your EGR valve is blocked, in such a case, it is expected that your preheat light comes on while driving on Kia Sedona because it is one of the problem of which it is meant to alert you. Have the status of your valve examined
  • Trouble associated with the turbo overflow valve, in this situation the ECU can no longer manage the turbo intake pressure, which can cause turbo boost and a disturbance in the operation of the turbo.
  • Trouble relevant to the injection, either an injector that has seized up or the injection pump that is malfunctioned by filings or other possible foreign bodies that affect its proper performance.
