What is the role of my Ford Tourneo glow plug light?

The primary role of the engine glow plug light, which is in most cases represented by a yellow coil, is to assure that your glow plugs are working properly. Indeed, it must light up when you switch on your Ford Tourneo 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. But, if it turns on while driving, it may reveal multiple troubles, we will try to detail the most important ones.

What to do if the glow plug light comes on while driving on my Ford Tourneo?

A glow light that comes on while driving on your Ford Tourneo or at any other time other than when the engine is started is designed to alert you to a fault other than your spark plugs, we will look at this now.

My Ford Tourneo glow light comes on and I’m having a loss of power

The first possibility is that you notice that your glow plug light comes on while driving your Ford Tourneo and that you also knowledge a loss of power. In such a case, several trouble can explain its lightning. Here is a list of the most important causes:

  • Trouble of EGR valve, in reality, if you go through a loss of power, it is possible that your EGR valve is clogged, in this case, it is obvious that your preheat light comes on while driving on Ford Tourneo because it is one of the failures of which it is supposed to warn you. Have the status of your valve inspected
  • Trouble linked to 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 in connection with the injection, either an injector that has seized up or the injection pump that is destroyed by filings or other possible foreign bodies that disrupt its proper performing.
  • Finally, the last problem that could lead to a glow indicator light on your Ford Tourneo coupled with a loss of power, is that your fuel filter is too dirty, you should encounter jerks because of a bad fuel flow in the engine.
