There are two ways of solving this code. Based on the problem location and type, you have to work on these two ways. Let’s see these solutions now.

If the Problem is in Glow Plug

If you find any problem with the glow plug then you have to work on the plug only. There is one possible cause that may happen with your glow plug. Here are some steps to do.

  • Step 1: Remove the glow plugs of cylinder 5. There are 4 plugs. Remove all of these carefully.
  • Step 2: Take a multimeter. This is one of the most used equipment that you will need to check the glow plugs.
  • Step 3: Check the plug resistance. A good plug will have resistance around 6 ohms. If the glow plug has more than 6 ohms then there is a problem with the glow plug. You have to change the whole set of it.
  • Step 4: The changing process is very simple. You have to take a new set of Plugs and replace the old one. 

In this way, you will be able to solve the glow plug issue if the code comes for and faulty glow plug. This is easy to do but you have to buy a new set.

If the Problem is in the Glow Plug Control Module

We all know the Glow Plug Control Module is another section that is responsible for showing the P0675 Code On 6.0 Powerstroke. Here is the solution to that problem.

  • Step 1: You have to remove the cover of the Glow Plug Control Module and then remove the module itself.
  • Step 2: Mop the GPCM carefully. You have to check the body of the GPCM if there is any crack in its body or not.
  • Step 3: Another thing you have to do in this section checks the connection ports of the Glow Plug Control Module.
  • Step 4: If the body goes damaged then you have to change the Glow Plug Control Module itself. You have to change it after a certain distance of running the vehicle.
  • Step 5: If the problem is in the port then clean it and re-connect the port.

That was all about the solution of the P0675 code on the 6.0 Powerstroke. I hope you get the solution. If you feel confused and don’t think you will be able to do it yourself then call for a mechanic. 

How Much Does It Cost To Solve The Error Code P0675?
