what is p1249 code on 6.7 Powerstroke + [Quick Fixing]

P1249 is an error code on the 6.7 Powerstroke engine that relates to the wastegate control valve performance. This valve regulates the amount of exhaust gas that bypasses the turbocharger. If this valve does not function properly, it can cause a decrease in turbocharger performance.

If you are facing this error code, physically inspecting the wiring and harnesses of the WGC solenoid is required. Cleaning the solenoid with compressed air might solve the problem. If not, you need to replace the WGC actuator.

Common CauseQuick Fix
Any faulty hose in the WGCCheck for blown hose and replace it
Fault WGC solenoid, actuator, or valveInstall the new actuator and reconnect the battery cable
Fuel contamination or injector issuesReplace the contaminated fuel or injector

What Does P1249 Code 6.7 Powerstroke Mean in my car?

If your 6.7 Powerstroke is producing the P1249 code, the wastegate control valve is not performing correctly. This can be caused by many things, including a faulty hose or a stuck valve. In either case, it’s important to get the problem fixed as soon as possible, as it can lead to further engine damage.

When the 6.7 Powerstroke displays the error code P1249, it simply implies that the wastegate can’t just open to lower the turbocharger performance boost. While this may not seem like a big deal, it can lead to some serious problems. If you’re not careful, you could end up damaging your engine or even causing an accident.

So, what can you do to avoid these problems?

  • First of all, make sure that you keep an eye on your boost pressure. If it starts to climb too high, slow down the throttle immediately.
  • Secondly, don’t forget to check your wastegate regularly. If it’s not functioning properly, it could cause your boost pressure to get too high and damage your engine.

If you follow these simple tips, you should be able to avoid any serious problems with your 6.7 Powerstroke.

4 most common Causing Factors Of The Error Code P1249 on 6.7 Powerstroke

There are some possible causes of the code p1249, and they are:

#1- Turbocharger Boost Solenoid

Code P1249 on 6.7 Powerstroke can be caused by a problem with the turbocharger boost control solenoid. This can be caused by several things, including a bad solenoid, a faulty connection, or a build-up of carbon deposits.

#2- EGR sensor

Another common cause is a faulty EGR sensor. Other causes can include a faulty EGR valve or a problem with the EGR system itself. If a faulty EGR sensor causes the code, it will usually need to be replaced. When a faulty EGR valve causes the code, it will need to be cleaned or replaced. If a problem with the EGR system causes the code, it will need to be repaired.

#3- Actuator

One more common issue on 6.7 Powerstroke engines is a faulty Wastegate Control (WGC) Actuator. The WGC actuator controls the amount of exhaust gas that bypasses the turbocharger. When it fails, it can cause the engine to run lean and set a p1249 code.

#4- Fuel Contamination, Valve Lash Adjustment, And Injector Issues

Yet, the most common causes of Code P1249 are fuel contamination, valve lash adjustment, and injector issues.

Fuel contamination is one of the most common causes of Code P1249. This can happen if water or debris gets into the fuel system. It can also happen if the fuel filter is not changed regularly. Valve lash adjustment is another common cause of Code P1249.

This is an adjustment that needs to be made periodically to keep the engine running smoothly. Injector issues can also cause Code P1249. If the injectors are not operating correctly, they can cause misfires and other engine problems.

Also, p2263 code 6.4 powerstroke is caused by a fuel delivery process issue. If you want to know about it, read my other blog regarding the issue.

How do I fix my P1249 code on 6.7 Powerstroke?

If you have a 6.7 Powerstroke and it’s throwing the code P1249, there is an easy fix.

1. Turbocharger Wastegate Solenoid

First, check the connector and wiring harness for the turbocharger wastegate solenoid. If there are any loose or damaged wires, replace them as needed.

Next, clean the turbocharger wastegate solenoid with a can of compressed air. Make sure to blow out any debris that may be blocking the solenoid valve.

If cleaning the turbocharger wastegate solenoid doesn’t fix the P1249 code, you may need to replace it.

2. Check for Blown Fuses

First, check to see if there are any blown fuses. If there are, replace them and see if that clears the code. If the fuse issue is not the problem, then it’s likely that the EGR valve is stuck open.

To fix this, simply clean the EGR valve with a carburetor cleaner and a brush. If that doesn’t work, you may need to replace the EGR valve.

3. Replace WGC Actuator

Also, when it comes to the actuator, to fix this problem, you will need to replace the WGC actuator. This is a simple process that can be done in about an hour. First, disconnect the red line of the negative battery cable. Then, remove the turbocharger inlet pipe and the WGC actuator mounting bolts. Finally, install the new actuator and reconnect the battery cable.

Look at the “Potential Reasons” section above. Examine the connections and accompanying wire harness carefully. Look for cracked, twisted, pushed-out, or rusted connection pins, as well as any other impaired parts.

common Symptoms associated with the Code P1249 On 6.7 Powerstroke?

Here are the symptoms you may experience if your Powerstroke has this code:

  • The check engine light will come on.
  • You may notice a decrease in power and performance.
  • Your fuel economy may suffer as well.
  • You may also hear strange noises coming from the turbocharger area.

If you’re experiencing any of these symptoms, it’s important to have your Powerstroke diagnosed by a professional as soon as possible. They will be able to determine whether or not code P1249 is the cause and advise you on the best course of action to take.

However, the symptoms of the p1316 code 7.3 powerstroke are regular misfires. If you are curious about it, read my other blog.

How Serious Is The P1249 Code 6.7 Powerstroke?

The code P1249 on the 6.7 Powerstroke engine indicates a problem with the turbocharger wastegate solenoid circuit. This is a serious code because it can lead to engine damage if not fixed promptly.

The wastegate solenoid is responsible for regulating the amount of exhaust gas that flows through the turbocharger. If this solenoid has a problem, it can cause the turbocharger to over spin and eventually fail. This can cause serious engine damage that will require expensive repairs.

If you have this code, it is important to take your vehicle to a mechanic as soon as possible. So they can diagnose and fix the problem before it causes any further damage.

frequently asked questions (FAQs)

If you’re experiencing engine trouble with your Ford, you’re not alone. Check out this FAQ section for possible solutions to your problem. With any luck, you’ll find the answer you’re looking for and be back on the road in no time.

1. What is a boost pressure control valve?

A boost pressure control valve is a device that regulates the amount of pressure in an engine’s turbocharger. By regulating the amount of pressure, the valve helps to keep the engine running at its optimal performance level.

2. How do you test a boost pressure control valve?

In order to test a boost pressure control valve, you will need the following materials: a Boost Pressure Control Valve (BPCV), a hand held vacuum pump, and a pressure gauge. First, connect the BPCV to the intake side of the engine. Next, attach the vacuum pump to the BPCV and turn it on.

Slowly increase the pressure until the desired level is reached. Finally, check the pressure gauge to see if the reading is stable.

3. What are P codes?

The powertrain (“P”) code errors are among the most frequent ones. P codes are a collection of codes. The engine, transmissions, and exhaust circuits error codes are all included in this collection of P codes. A P300 code, for instance, is referred to as a random discharge code. It denotes that either one or all of the pistons aren’t producing quite as much energy as they should.


If your truck is displaying a P1249 code, don’t panic. This code is common on 6.7 Powerstroke trucks and can often be resolved with a simple fix. In this article, I’ve walked you through what the P1249 code means and how to troubleshoot it.
