What Does P1247 Code Means On 7.3L Powerstroke?

When the powertrain control module of a Ford 7.3L Powerstroke detects low pressure from the Manifold Absolute Pressure (MAP) sensor, it generates a P1247 Code 7.3 Powerstroke, which by definition means “Turbo Boost Pressure Low”. This issue can be caused when the turbocharger is unable to produce sufficient airflow for maximum engine performance.

Symptoms Of Getting The P1247 Code 7.3 Powerstroke

Visible symptoms accompany the codes, such as P1247, which is a diagnostic trouble code. These symptoms are usually so grave that they cannot be ignored:

  • CEL (Check Engine Light) is Active
  • Shaky & Rough Driving Experience
  • Losing Power On a Daily Basis 

Victimization of this error code will leave one feeling unsatisfied with their truck.

The Causing Factors Of The Error Code P1247

The Causing Factors Of The Error Code P1247
The Causing Factors Of The Error Code P1247

The P1247 error code can be caused by a variety of factors. A few common causes for this DTC include fuel pressure sensors, faulty wiring, and low-quality fuel:

  • Damaged Manifold Absolute Pressure Sensor Hose
  • Crossover Tube or Air Intake Manifold Hose Leaks
  • Faulty Manifold Absolute Pressure Sensor
  • Low Turbo Boost Pressure
  • Faulty PCM (Powertrain Control Module) 

The fifth of these causes is only seen in rare occurrences; thus, it should not be overlooked if this code indicates damage to the wiring. Even if a diagnosis points to damaged wiring as the source of the problem, it is important that all possibilities are taken into account.

How Seriousness Is Code P1247 On 7.3L Powerstroke?

Ignoring this code could lead to long-term problems, as it is likely to be repeated after 20-30 miles even if the initial instance of the code is cleared without rectifying the underlying issue. Taking such risks on a long journey would be detrimental to the driving experience and should therefore be avoided. To ensure that no further issues arise, proper troubleshooting methods should be followed to solve this error code properly.

How To Solve P1247 Error Code On 7.3L Powerstroke?

When it comes to troubleshooting the DTC 1247, one should generally check and replace a few components of the engine. It is essential that they have the proper equipment before attempting to resolve any issues. With said equipment in hand, the process can then move forward.

Check Manifold Absolute Pressure Sensor Hose

Examining the MAP sensor hose is necessary, as any damage or cracks could be responsible for the error code. Replacements are available at a relatively inexpensive cost, and it should be checked to see if there is an improvement in performance after replacing them.

Check Manifold Absolute Pressure Sensor

The next step in the process is to check the MAP sensor itself. This device calculates airflow and sends information to the Powertrain Control Module (PCM). Should it be faulty, incorrect data may be sent to the PCM, resulting in a need for replacement at an approximate cost of $130. Replacement of this part should preferably be done by a professional.

Check Air Intake Manifolds

Careful examination of the air intake manifolds is recommended, as this is where the MAP sensor can be found. When assessing them, it should be checked for potential leaks, blockages, or misrouting. Contamination must also not be overlooked; any signs of it should result in an immediate replacement.

Check Powertrain Control Module

If the methods mentioned above fail to resolve the error code, suspecting a potential problem with the PCM is advisable. A faulty PCM can bring up various types of error codes, P1247 being one of them. It is highly recommended that an expert technician inspects the engine before making any decision related to replacing or repairing the PCM in order to get accurate results and avoid further complications.

How Much Does It Cost To Solve The Error Code P1247

Depending on the necessary replacement parts, resolving the error code P1247 may cost between $20 and $500 or more.

Let me break down the costs for you so that you can calculate easily: 

  • Replacement Of MAP Sensor Hoses Costs $20
  • Replacement Of MAP Sensor Costs $130 & above
  • Replacement Of Air Intake Manifolds Costs $80 & above
  • Replacement Of PCM Costs $500 & above 

It is important to remember that auto shops typically charge an additional fee of $75-$150 per hour for replacements.

Common Mistakes While Solving The P1247 Code

Avoiding common mistakes while attempting to solve an error code is essential, as it is likely that several errors will be made during the process.

  • Not Reading Technical Bulletin Of The Specific Model Thoroughly
  • Not Checking Other Possible Causing Factors Before Inspecting PCM

Staying aware of common errors while undertaking the fixing job will give one an advantage over others.

Additional Comments To Consider Regarding The P1247 Code

The DTC P1247 is a highly challenging code to decode for general users, as it necessitates inspecting multiple connections and hoses related to the manifold absolute pressure sensor. It may be wise to take professional advice if one wants to avoid paying expensive auto shop fees initially. If any costly solutions are proposed later on, they should nevertheless be considered to ensure optimal performance of the truck.
