The trouble code system of a vehicle is an example of very improved technology. This helps the drivers or mechanics to understand the main problem the vehicle is facing. This also helps them to fix the problem fast.
The popular engine 6.0 has some trouble codes that determine some problems with this engine or vehicle. Among the trouble codes of 6.0, P0671 is one. In this article, we will know what is the P0671 code on 6.0 Powerstroke and how to fix this. So, let’s see everything.
What Does P0671 Code Mean On 6.0 Powerstroke?
The P0671 code is a generic trouble code that is set when the Powertrain Control Module (PCM) has detected a problem with the glow plug of cylinder 1. The P0671 code on a 6.0 Powerstroke is an indication that there is a problem with the glow plugs.
The code can be caused by a number of things, including a bad glow plug, wiring problems, or a fault in the ECM. If you have this code, it’s important to troubleshoot and fix the problem as soon as possible to avoid further damage.
Symptoms Of Getting The P0671 Code On A 6.0 Powerstroke
We know that the trouble code P0671 on 6.0 Powerstroke means that the glow plug of cylinder 1 has some problems. Maybe this is not being able to generate enough heat in it or maybe it is completely damaged.
If that happens in any vehicle then the engine will not be able to generate enough power and sometimes the acceleration will fail again and again. These are some common symptoms of the code P0671 code on 6.0 Powerstroke. But some more symptoms are there. Let’s see them:
- Starting Problem in Cool Weather
- Low Power
- Creating High Smoke in the exhaust
- Acceleration Problem
- Fail to Start the Engine Again and Again
- Check Engine Light On
The Causing Factors Of The Error Code P0671 on 6.0 Powerstroke
As we know that the main causing factor of this code is the glow plug of cylinder 1. But why does this cylinder glow plug refuse to work? There are some reasons behind this. Let’s see what are these causing factors of the error code P0671 on 6.0 Powerstroke.
- The Glow Plug Wire Problem
- Glow Plug Control Module Fault
- Short Glow Plug Circuit
- Loose Electrical Connection
These are the cause of the low heat generation in cylinder 1 by the glow plug. And for that reason, the code P0671 appears on a 6.0 Powerstroke. When this code appears, some people think about the seriousness of this code. Let’s see how serious this code is for your vehicle.
How Serious Is Code P0671 On 6.0 Powerstroke?
The seriousness of this code will appear to you if you look at the symptoms of this problem. The symptoms are too serious and hesitating for you as a driver and owner. It will fail to start the engine again and again. If it is cold in your area then the engine may refuse to start at all.
If this code stays for a long time and you take no step to solve this then you will find an imbalance of your cylinder performance and the engine will affect in the long run. This is an example of the seriousness of the code P0671 on 6.0 Powerstroke.
Besides these, the acceleration and the low power problems will become worse gradually. So, we can say that this code is serious enough to fall you in emergency conditions and will do a lot of damage to your engine.
How To Solve P0671 Error Code On 6.0 Powerstroke?
In this fixing process, we are going to show you 2 practical solutions. There are two simple DIY solutions you can try to solve this problem. Let’s see what these methods are and all the steps to fix them.
If the Glow Plug is Problem
We know there are two possible causes of this trouble code. One is the glow plug itself and another is the Glow Plug Control Module. We will see how to find the exact cause in case of your vehicle and then will move to a solution.
Step 1: Locate the Glow Plugs
First, you have to find the glow plug. For this, check cylinder 1 and find the glow plugs. Then you have to carefully remove the glow plugs from the engine. You have to remove the whole set of plugs for a better result.
Step 2: Test the Glow Plugs
In this step, you have to test the glow plugs of cylinder 1. To test, you may use a multimeter. In this process put one end of the multimeter on the connecting bolt and another end at the plug body. You have to measure the resistance of the plug.
Now, read the result of the multimeter display. Remember that resistance of less than six ohms usually means the glow plug is good. You have to repeat the procedure for the remaining glow plugs until they have all been tested.
Step 3: Change the Glow Plugs
Now you know how to test and what is the result of a good glow plug. If any of the glow plugs fail to test, it is recommended that the entire set be replaced. Only replacing the old and faulty glow plug is the best way to solve the error code P0671 on 6.0 Powerstroke.
If the problem is in the Glow Plug Control Module
The glow plug control module may also be faulty. In that case, you have to follow the following process to fix this problem. Let’s see the steps.
Step 1: Test the Glow Plug Control Module
First, carefully remove the glow plug control module from the vehicle. Now you have to inspect the control module visually. Inspect the module to make sure it hasn’t been contaminated by a leak from another engine component.
If the control Module looks good in the visual inspection then you have to check the glow plug control module itself and its electrical connections for any damages. In this case, you may use the multimeter to measure the voltage of the control module by putting the meter ports on the connection ports.
Step 2: Replace If it is Damaged
If damages are found then replace the glow plug control module, any miss voltage is found then you have to replace the Control Module. Replacing your glow plugs or glow plug control module is a straightforward project.
Every time you drive your vehicle around 60,000 miles or 95,000 kilometers. You have to change the control module. This is recommended by the manufacturer. So, this is the process of fixing the P0671 code on 6.0 Powerstroke.
How Much Does It Cost To Solve The Error Code P0671?
We have seen the two different ways of fixing the P0671 code on 6.0 Powerstroke. Both the methods are different and the solution of two different causes. So, the cost is also different. If you need to change only the glow plugs then you will have to spend around $25 to $50.
But if the glow plug control module is found damaged then you have to spend a big amount. The amount is around $10000. This is not fixed because different times, places, and models determine the price and cost.
Common Mistakes While Solving The P0671 Code
The most common mistake a driver or an owner does is not giving priority to this problem. They think the vehicle is going well and not having any serious problems so this code is not so serious an issue for the vehicle.
But this is the mistake we do related to this code. We should take the code seriously and step down to the solution process. And solve this code as soon as possible.
Additional Comments To Consider Regarding The P0671 Code
Try to read the whole process before you start solving the code. And you should collect all the instruments that will be needed to solve this code. When any of the symptoms you find in your vehicle, you should start the troubleshooting process. The troubleshooting or inspection should be done taking time.
That was all about the code P0671 on 6.0 Powerstroke. We hope you get symptoms, causes, common mistakes, cost, and how to fix this code. That was all for today. Thanks for reading from us.
