What is the purpose of my Mitsubishi Asx 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 make sure that your glow plugs are working correctly. In fact, it must light up when you switch on your Mitsubishi Asx 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 meant to stay or come on while driving with your automobile. Nevertheless, if it comes on while driving, it may show different failures, we will try to detail the most important ones.

What to do if the glow plug light comes on while driving on my Mitsubishi Asx?

A glow light that comes on while driving on your Mitsubishi Asx or at any other time other than when the engine is started is meant to alert you to a fault other than your spark plugs, we will look at this now. Whatever the case, connecting your vehicle to the diagnostic tool will allow you to precisely translate the cause for the light up of your glow light.

The first probability is that you detect that your glow plug light comes on while driving your Mitsubishi Asx and that you also knowledge a loss of power. In such a case, different concerns can demonstrate its presence. Here is a list of the most important causes:

  • Issue of EGR valve, in fact, if you undergo a loss of power, it is possible that your EGR valve is blocked, in such a case, it is obvious that your preheat light comes on while driving on Mitsubishi Asx because it is one of the problem of which it is supposed to alert you. Have the status of your valve looked at
  • Trouble related to the turbo overflow valve, in this situation the ECU can no longer manage the turbo intake pressure, which can result in turbo boost and a perturbation in the operation of the turbo.
  • Trouble linked to the injection, either an injector that has seized up or the injection pump that is broken by filings or other possible foreign bodies that disrupt its proper performance.
  • Finally, the last problem that could lead to a glow indicator light on your Mitsubishi Asx coupled with a loss of power, is that your fuel filter is too dirty, you should feel jerks because of a bad fuel flow in the engine.

  • 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 repair shop.
  • Faulty injection pressure sensor, ECU error
