What is the purpose of my Dodge Dart glow plug light?

The primary role of the engine glow plug light, which is generally represented by a yellow coil, is to assure that your glow plugs are working effectively. Indeed, it must light up when you switch on your Dodge Dart to tell you that they are heating the intake air in your cylinders and must go out after a few minutes when the engine is running. This preheat light is therefore not supposed to stay or come on while driving with your motor vehicle. Nevertheless, if it comes on while driving, it may indicate several issues, we will try to summarize the most important ones.

  • Issue of EGR valve, indeed, if you go through a loss of power, it is possible that your EGR valve is blocked, in such a case, it is logical that your preheat light comes on while driving on Dodge Dart because it is one of the problem of which it is expected to alert you. Have the status of your valve examined
  • Issue linked to the turbo overflow valve, in this situation the ECU can no longer control the turbo intake pressure, which can result in turbo boost and a disturbance in the performance of the turbo.
  • Issue 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 disrupt its proper functioning.

  • You have a false contact somewhere in your electrical circuit, test the other options first because it is not easy to find it alone, we recommend you to go to your mechanic.
  • Faulty injection pressure sensor, ECU error
