What is the purpose of my Maserati Ghibli glow plug light?

The primary purpose of the engine glow plug light, which is in most cases represented by a yellow coil, is to make sure that your glow plugs are working effectively. In reality, it must light up when you switch on your Maserati Ghibli 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 indicate different failures, we will try to point out the most important ones.

What to do if the glow plug light comes on while driving on my Maserati Ghibli?

A glow light that comes on while driving on your Maserati Ghibli or at any other time other than when the engine is started is intended to warn you to a problem other than your spark plugs, we will check out this now. In any case, connecting your vehicle to the diagnostic tool will allow you to properly understand the reason for the light up of your glow light.

My Maserati Ghibli glow light comes on and I’m suffering from a loss of power

The first probability is that you detect that your glow plug light comes on while driving your Maserati Ghibli and that you also encounter a loss of power. In this instance, several complications can describe 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 this instance, it is expected that your preheat light comes on while driving on Maserati Ghibli because it is one of the issue of which it is intended to notify you. Have the status of your valve looked at
  • Problem linked to the turbo overflow valve, in this situation the ECU can no longer control the turbo intake pressure, which can bring about turbo boost and a perturbation in the operation of the turbo.
  • Problem related to the injection, either an injector that has seized up or the injection pump that is damaged by filings or other possible foreign bodies that affect its proper functioning.
  • Finally, the last problem that could lead to a glow indicator light on your Maserati Ghibli coupled with a loss of power, is that your fuel filter is too dirty, you should come to 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 Maserati Ghibli

To finish , we’ll give you the reasons for a glow plug light that comes on on your Maserati Ghibli without you feeling any difference in power or car behaviour. Generally, this is an electronic problem:

  • Glow plug relays or fuses to be replaced, 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 problem.
  • You have a false contact somewhere in your electrical circuit, test out 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
