At present, manufacturers have installed universal codes that are recognized by all manufacturers. These codes have been defined so that diagnostic equipment can read them. These codes are provided by onboard diagnostic (OBD) systems in order to diagnose specific issues.
The p1249 code on the 6.7 powerstroke is a code that indicates the wastegate failed the steady state test. It means the wastegate is not opening to reduce the turbo boost.
Once you receive the code, you might be wondering exactly how you can fix it. Well, no worries! In this article, we will let you know about the code p1249 in detail, including how you can get rid of it easily.
What Does P1249 Code Mean On 6.7 powerstroke?
The code p1249 on a 6.7 powerstroke means wastegate control valve performance. When you get the code p1249 on the 6.7 powerstroke, it indicates that the wastegate is not being able to open at all. At the same time, the turbo is being overboosted.
The wastegate primarily has the job of reducing the boost of the turbo by clearing the way. It is supposed to allow the excess gas to pass by the wheel and, as a result, reduce the turbo boost.
When the wastegate fails to open in order to let that excess gas pass, the vehicle will face an overboosted turbo. That is exactly when the code p1249 shows up.
We’ll let you know more about this code and its causes, later in this article when discussing the solution. Here is the dissection of code P1249:
- p- Powertrain, the system of components that propel your car forward.
- 1-Generic manufacturing code derived from the SAE standard
- 2-Specific system related to the wastegate control
- 49-Describes the specific fault information. In this case, the failed watergate control valve performance.
How Serious Is Code p1249 On 6.7 powerstroke?
Code P1249 on powerstroke might not be the cause of an emergency but it is, infact, pretty serious of a code for your 6.7 powerstroke.
If your wastegate is broken or doesn’t work perfectly, more of the raw fuel will be exhausted from your engine without being burned. As a result, a part of your fuel will suffer rapid loss.
A failed wastegate results in your vehicle having an overboosted turbo. It forces more air inside the engine and causes it to overspeed often. Too much boost like this for an extended period of time can cause turbo or engine failure.
You might find yourself having rough or sluggish rides in your car because of this code.
It is because it causes damage to the internal components of the car, which can eventually lead to complete engine failure at some point. So, you should fix this code as soon as you can without neglecting it.
What Causes Code p1249 On 6.7 powerstroke?
P1249 code can show up on your car unannounced, leaving you wondering about its cause. A lot of factors can cause P1249 codes on 6.7 powerstroke 6.7. However, the most common cause is a failed wastegate valve. Other potential causes include:
- Solenoid, actuator or valve of the wastegate is damaged.
- Faulty wastegate hose or port.
- Poor electrical connection with the fuel injector.
- Too much stress from an aging turbocharger.
- Pressure actuator of the turbo engine stopped working.
- Leakage in the intake air system.
- Damaged PCM (Powertrain Control Module).
- Fuel injector harness is open or shortened.
- Increasing the boost pressure from a turbocharger.
Other Symptoms Of Getting p1249 Code On 6.7 powerstroke
If the code p1249 shows up on your 6.7 Powerstroke, the car will show a few symptoms indicating the issue.
Most of the time, the symptoms are so low-key that you usually wouldn’t notice them at one go. But in some cases, you can notice the following symptoms of this code:
- Driving becomes rough and sluggish
- The engine lights don’t turn on
- During acceleration, the turbo doesn’t boost much
- Turbo boost pressure keeps oscillating
- Fuel runs out too fast.
How To Fix The p1249 Code On The 6.7 Powerstroke?
Now let’s take a look at how we can fix the code p1249 on the 6.7 powerstroke. You will need certain equipment to follow the procedure required to fix a damaged or failed wastegate on your car.
Similar to solving any problem, first you need to figure out the exact reason for the issue. Therefore, test out the components that originally caused the wastegate to fail.
Such components you need to check are- the watergate hose or port, actuator, intercooler port, and the solenoid.
1. Check and Fix The Wastegate Hoses or The Ports
The wastegate hose powerstroke 6.7 is made of silicon or rubber, and it connects to small clamps at the end. Contamination from the oil and high temperatures can cause the control hose to split over time.
To check the control hose, perform the following vacuum test on it.
- Disconnect the red hose from the actuator first.
- Install the Gauge Bar 014-00760 vacuum pump and run the vacuum.
- If the hose doesn’t hold the vacuum, you will need to replace it.
Follow these steps to replace the wastegate control hose:
- Raise the car on a hoist.
- Open the car hood and remove the engine cover.
- Remove the turbocharger from the engine for safety purposes.
- Find the damaged wastegate hose and disconnect it.
- Remove the clamps and separate the damaged hose.
- Install a new control hose with new clamps at the sides.
- Top up with oil or coolant if necessary.
- Reconnect the turbocharger again with new gaskets installed.
- Restart the car and do a test drive to ensure a successful wastegate control hose replacement.
2. Check and Fix The Intercooler Port
To figure out exactly what fix your intercooler ports need, you need to run the above mentioned vacuum test on them again.
Use the Gauge Bar 014-00760 vacuum pump and run the vacuum test on your intercooler port. There could be two possible fixes:
- If the port can hold the vacuum, you need to unplug your intercooler ports properly. Clean up the plugged ports thoroughly to get rid of the code.
- If the port does not hold vacuum, the problem is with the actuator. Let’s check the fix for that next.
3. Check and Fix The Actuator
You will need to run the same vacuum test with your 6.7 powerstroke actuator too to figure out the solution it needs. Depending on whether the actuator can hold the vacuum, there are two ways to fix this problem too.
- If the actuator can hold the vacuum, you need a new linkage. Install a new wastegate control linkage and your problem will be solved.
- If the actuator can’t hold the vacuum, the actuator needs to be replaced. In that case, the best idea would be to contact a professional to replace the actuator. Since the equipment needed for this process is hard to find and the process is too tricky.
4. Replace the Powertrain Control Module
Replacing the PCM is the last possible solution we recommend. If you see that none of the fixes are working and every other related component is running smoothly, the problem is with the Powertrain Control Module.
Unfortunately, since it is the only way left to fix the code p1249 on powerstroke 6.7, you will need to replace the PCM. However, keep in mind that it is a very costly option.
How Much Does It Cost To Fix The 6.7 Powerstroke p1249 Code?
The cost of fixing the code P1249 on 6.7 powerstroke depends on the cost of testing and finding the issue and the cost of replacing the parts. This labor cost varies depending on the location and car model.
The labor hour for testing and fixing the problem is around 1 hour. Most repair shops will charge you around $75 to $150 per hour.
If you need to purchase a new wastegate hose, it will cost $150 to $500 and upwards. A new actuator will cost around $300. The PCM is the most expensive purchase as it can cost you anywhere between $500-$1200.
Can You Drive Your 6.7 Powerstroke With Code p1249?
It is recommended to not drive the car after getting the code p1249. But there is no chance of any serious damage to the car if you drive it with code p1249.
Extended periods of driving after getting the code p1249 can slowly affect the turbo and consequently the engine. So, for the future long term healthy engine, it is recommended to fix the code before driving the car.
We will answer a few commonly asked questions regarding this code p1249 in this part. Hopefully you will get your desired answer in this section.
What Does The Code P1249 Affect?
The code p1249 affects the wastegate and the turbo of the engine simultaneously.
There will be excess air and fuel inside the engine which will result in a malfunctioned turbo. Therefore, the affected parts by the code p1249 are the wastegate, the turbo and the engine.
How To Diagnose The Code P1249?
In order to diagnose the code p1249, check the resistance of the solenoid. Measure the resistance between the pins 1 and 2.
If it is less than 50 ohms then you have a damaged wastegate solenoid which caused the code to appear. Checking for faulty wirings and connections are also the next step of diagnosing this code.
Which Vehicle Parts Should I Check Because Of Code P1249?
After receiving the code p1249, the first part you should check is the wastegate hoses and ports.
After that, move on to checking your solenoid and actuator for any kind of damage. Check the valve and PCM as your last resort if you don’t find anything amiss with the other parts.
Now if your car shows you the code p1249, there’s no need to panic or worry anymore. Just use the methods mentioned in this guide to get rid of it. Code p1249 is not a serious safety issue for the car or yourself. So fixing it is not as much of an emergency.
If you still find yourself struggling to execute any of these methods, consult a professional to complete the tough replacements for you. The labor cost required is within a reasonable price if you do not have the right equipment to fix it yourself.
