What Is P1249 Code On 7.3 Powerstroke & How To Fix It?

by

With p1249 code 7.3 Powerstroke, getting codes at random is rather typical. So, one of them is the P1249. This page is for you if you get P1249 and don’t know what it means.

I’ve covered everything there is to know about error number P1249. Follow the steps in this article to learn how to fix the code.

What Does P1249 Code Means On 7.3L Powerstroke?

P1249 is one of the Ford 7.3L Powerstroke DTCs (Diagnostic Trouble Codes). The PCM detected that the turbo was over-boosted, as indicated by this DTC.

P1249 is an indication of Wastage Control Valve Performance. The wastegate valve’s principal function is to enable surplus turbocharger gases to bypass the wheel and lower the boost.

When the code P1249 looks, it simply implies that the wastegate will not open to lower turbo boost. As a result, your car will have an over-boosted turbo, which is all that the code P1269 on a 7.3 indicates.

Symptoms Of P1249 Code 7.3L Powerstroke

Most of the time, the P1249 code does not indicate any symptoms that the user may uses to track it down. In rare situations, you may notice the following symptoms of DTC P1249:

  • The plastic ring around the front (left and right) hubs is breaking.
  • Driving was rough and slow.

That’s it; you shouldn’t notice anything more than the symptoms listed above.

Causes of the Code P1249 error on the 7.3L Powerstroke

As previously stated, the error code P1249 might emerge for a variety of reasons. The following are some of the most common causes of P1249:

  • Wastage Control Hose Solenoid, Actuator, and Valve Damage
  • The Wastage Control Hose or Port has become clogged.
  • Shorted or open fuel injector harness
  • Fuel Injector Electrical Connection Failure
  • Using a Performance Chip (Example: A 40HP Super Chip)
  • There is a leak in the intake air system.
  • Powertrain Control Module Failure (PCM)

Some of these causes are more serious than others, and you must determine the cause before becoming concerned about the P1249 code.

How Serious Is P1249 Code 7.3 Powerstroke?

The P1249 code has a very low chance of causing damage to your Powerstroke engine. Unfortunately, there is a small chance that you will have significant engine difficulties such as – slow & rough journeys for this code.

That is why you should not neglect this code and try to solve it as soon as possible. In the next section, I’ve included detailed information on how to solve the error code for your convenience.

How Can I Fix The P1249 Error Code On 7.3L Powerstroke?

You cannot do the removal operation with your hands tied behind your back. Before beginning the operation, ensure that you have all of the essential equipment.

If you have your equipment ready, let me explain the finest troubleshooting procedure for problem number P1249.

Note: When I said “test,” I meant “see if the specific component can retain the vacuum appropriately.”

Examine the wastegate control hoses.

First with checking the WGC hoses. Remove the red hose from the wastegate control hose actuator first.

Install the vacuum pump Gauge Bar 014-00760. Do the test to see if the hose can hold the vacuum.

Depending on the outcome, you’ll need to conduct more tests. As an example:

If the vacuum hose fails, inspect the intake port.
Check the intercooler port if the hose isn’t holding the vacuum.

Check the Intake Port

To begin, remove the red pipe from the charge air cooler housing. Now, restart the test and follow the results:

  • If the hose does not hold a vacuum, the air cooler is blocked. Clear it up, and the P1249 error should be resolved.
  • If the hose holds a vacuum, the WGC hose is defective. This code should be resolved when replacing the WGC hose.

Check the Intercooler Port

Begin by removing the red hose from the charge air cooler housing and attaching the Gauge Bar 014-00760 vacuum pump to the port.

Now conduct the test to see whether the actuator can maintain the vacuum:

  • If the hose is holding a vacuum: it suggests the intercooler ports are clogged. Clear the plugged-in ports thoroughly, and this code should be gone for good.
  • If the hose does not hold the vacuum: something is wrong with the actuator. Examine the actuator.

Check the Actuator

Install the Gauge Bar 014-00760 vacuum pump on the wastegate control actuator as you would any other component. Check to see whether the actuator can withstand the vacuum.

  • If the actuator holds a vacuum: a new WGC linkage must be installed. The error code P1249 should be resolved as a result of this.
  • If the actuator does not hold a vacuum: you have a malfunctioning actuator. Replace the actuator and the issue should be resolved.

Powertrain Control Module Inspection and Replacement: The Final Route

If everything is working properly and you still don’t know what is causing the DTC P1269 to show on occasion, the only option is to replace the PCM.

Since the PCM is costly and should only be considered as a last resort, I have placed it at the end.

Common Errors Made While Fixing The P1249 Code

Being a novice with the 7.3L Powerstroke, you may make various mistakes while decoding this code. Avoid the following typical blunders:

  • Not Utilizing Required Equipment When Carrying Out The Job
  • Without checking connectors, wiring, and anything else before PCM

Further Issues Considering the P1211 Code

If you don’t detect any visual indications near the engine, don’t worry about P1249 code 7.3 Powerstroke. If you’ve added a performance chip, the code is likely to occur. That is why, before you break a sweat trying to solve this error code, you should first check the reason.

Conclusion

I hope this post was useful in answering your questions about the P1259 code 7.3 Powerstroke.

It’s now up to you whether you want to crack the code or leave it alone. It is perfectly OK to disregard the code unless there is a performance issue.
