If the Glow Plug is Faulty
The glow plug is one of the most complex parts of the vehicle. It has some sensitive components that can face some troubles and it may be damaged. There is a coil inside the plug. That creates heat inside the cylinder. You have to check the glow plug for any fault it has.
To check the glow plugs, you have to take one multimeter. Then you have to check the resistance of these plugs. If the resistance is more than 6 ohms then the plugs are faulty and you have to change all 4 plugs from cylinder 7.
If you remove old glow plugs and replace these with new plugs then it should be okay now. You will check again and the code will not come again.
If the Problem is in Connection
The glow plugs need some electric power to generate heat. If the connection is poor then the plugs will not work properly. They will not be able to generate enough power and the code will appear.
In that case, You have to remove the connection completely. Then you have to clean all the ports of the glow plug control module and battery section. Then replug the connection. I hope the problem is gone now.
Now check the voltage of the connection. If the voltage is okay then there is no problem anymore. But if the voltage is lower than the expected level then you have to change the wire and connectors too.
If the problem is in GPCM
We know that the Glow Plug Control Module may face some problems. If that is true for your engine then you have to change the GPCM. Usually, everyone has to change this in every 95,000 KM an engine runs.
These were all possible solutions to this code on your vehicle. I hope you get all these.
How Much Does It Cost To Solve The Error Code P0677?
The cost to solve this code from your engine is not fixed. It may be higher if the problem is in the Glow Plug Control Module. But if the problem is in the Glow Plug itself and in the electric connection then it will be low.
The possible cost will be from $50 to $5000. If you have to change the GPCM then the cost will be around $5000. But if the problem is in the glow plug then the cost will be around $150 to $200. The connection problem will cost you from $50 to $100.
Common Mistakes While Solving The P0677 Code
The most common mistake we make while solving this code is not inspecting everything carefully. If the code appears that means that there is a possibility of a number of causes behind it. So, you have to inspect all the possible causes and then make a decision.
