What is the goal of my Mitsubishi Eclipse glow plug light?

The primary intent of the engine glow plug light, which is generally symbolized by a yellow coil, is to make sure that your glow plugs are working correctly. In reality, it must light up when you switch on your Mitsubishi Eclipse 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 car. However, if it comes on while driving, it may reveal several troubles, we will try to explain the main ones.

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

A glow light that comes on while driving on your Mitsubishi Eclipse or at any other time other than when the engine is started is intended to inform you to a problem other than your spark plugs, we will take a look at this now. Whatever the case, connecting your vehicle to the diagnostic tool will allow you to properly understand the motive for the light up of your glow light.

My Mitsubishi Eclipse glow light comes on and I’m encountering a loss of power

The first possibility is that you detect that your glow plug light comes on while driving your Mitsubishi Eclipse and that you also encounter a loss of power. In this instance, different trouble can explain its presence. Here is a list of the main motives:

  • Issue of EGR valve, in reality, if you suffer a loss of power, it is possible that your EGR valve is blocked, in this instance, it is logical that your preheat light comes on while driving on Mitsubishi Eclipse because it is one of the issue of which it is intended to alert you. Have the status of your valve examined
  • Trouble related to the turbo overflow valve, in this situation the ECU can no longer manage the turbo intake pressure, which can lead to turbo boost and a perturbation in the operation of the turbo.
  • Trouble in connection with 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 operation.
  • Finally, the last issue that could lead to a glow indicator light on your Mitsubishi Eclipse 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.

My glow plug light comes on or is flashing but no difference on the performance of my Mitsubishi Eclipse

To conclude, we’ll give you the reasons for a glow plug light that comes on on your Mitsubishi Eclipse without you feeling any difference in power or car behaviour. In most cases, this is an electronic problem:

  • Glow plug relays or fuses to be changed, test and change if necessary.
  • A contactor/potentiometer on one of your pedals (brake, accelerator or clutch) has failed, often a simple de-seizure will be enough to get rid of the issue.
  • You have a false contact somewhere in your electrical circuit, check the other alternatives first because it is not easy to find it alone, we encourage you to go to your auto mechanic.
  • Faulty injection pressure sensor, ECU error
