P2563 Code On 6.4 Powerstroke: What Does It Mean?

The P2563 code is a diagnostic trouble code (DTC) that is specific to diesel engines, specifically the 6.4L Powerstroke engine used in Ford trucks.

A 6.4 Powerstroke engine sometimes reveals an error code P2563 on a diagnostic tool which is a good indicator of a problem with the turbocharger boost control position sensor circuit.

The turbocharger boost control position sensor circuit provides a range of values that monitor the status of the turbocharger. 

The sensor then sends signals (range of values) to the Engine Control Module (ECM) on the amount of boost being produced by the turbocharger.

When the sensor is not sending signals within the expected range usually between 9-14 pounds, it triggers the Check Engine Light (CEL), which confirms an issue with the turbocharger through the P2563 code.

Causes Of P2563 Code on 6.4 Powerstroke

Faulty sensor:

This sensor measures and sends information to the engine control module (ECM). If the sensor is physically damaged, it may cause errors resulting in the P2563 code.

Wiring and connections:

The turbocharger boost control position sensor is connected to the ECM via wires. If these wires are loose or damaged, the sensor may not be able to communicate properly with the ECM, resulting in the P2563 code.

Soot buildup:

The turbocharger boost control position sensor is located in the turbocharger and can become clogged with soot, preventing it from moving freely. This can cause the sensor to send incorrect information to the ECM, resulting in the P2563 code.

Car software malfunction:

In rare cases, a software malfunction in the car’s engine control module (ECM) can cause the P2563 code to be triggered. 

Symptoms of the P2563 on 6.4 Powerstroke

Check Engine Light:

When the check engine light comes on, you need to use a scan tool to find the specific engine error, such as the P2563.

Reduced Engine Performance:

Errors attributed to P2563 cause poor engine performance, especially at high speeds or when transporting heavy loads. This poor engine performance is also seen during acceleration which takes longer than normal to respond to changes in throttle.

Decreased Fuel Efficiency:

Poor fuel efficiency is also a symptom of the P2563 Code on 6.4 Powerstroke. Due to poor engine performance, fuel efficiency decreases as the engine tries to produce more power resulting in more fuel consumption.

Unusual noise in the vehicle:

The turbocharger is concerned with increased airflow to the engine. If airflow to the engine is affected, it leads to the production of unusual noise by the vehicle.

How Should You Diagnoses Turbocharger Boost Control Position Sensor Circuit Issues

  1. Retrieving the trouble codes from the vehicle’s computer using a scan tool and any other additional information stored in the ECM
  2. Visual inspection of the turbocharger and the sensor for physical damage (dents, cracks, leaks, etc.), wiring, and connections (loose connections or damaged wires) and inspecting the operation of the sensor, including the setting of the software code.
  3. Performing a road test to check for:
    • Engine Check Light
    • Poor Engine Performance
    • Fuel Efficiency
    • Power Output
    • Unusual Noise

Common Mistakes When Checking P2563 6.4 Powerstroke

One common mistake when diagnosing a P2563 code on a 6.4 Powerstroke diesel engine is not addressing the code right away. The error code may be related to other issues with the turbocharger and, if left untreated, can cause additional codes to appear. This can make it more challenging to identify the root cause of the problem and can lead to unnecessary repairs.

Another mistake is not verifying that the issue has been resolved. After the mechanic has fixed the problem, it is crucial to clear the codes from the engine control module (ECM) and retest the vehicle to ensure that the problem has been resolved. 

Repairing p2563 code 6.4 Powerstroke

You can fix P2563 Code on your 6.4 Powerstroke by following the steps below:

  1. Checking for physical damage to the sensor for things such as wear and tear, leaks, dents, cracks, etc.  
  2. Checking the wiring and connections of the sensor to ensure that there are no loose connections or damaged wiring that have caused the sensor to malfunction 
  3. Cleaning the sensor to remove the soot. Soot on the sensor may cause the sensor not to move as expected (sticky/seized), thus reporting the wrong values of the turbo boost control leading to the error. Cleaning is best done by spraying brake cleaner fluid or liquid soap and gently using a rag to wipe off soot. Test the sensor movement to ensure it moves smoothly
  4. Replacing the turbocharger boost control position sensor if it is not functioning properly, has visible physical damage, is not moving smoothly after cleaning, or if there is an issue with the wiring. 
  5. Performing a software update of the engine control module to ensure that a software glitch did not cause the error

Where Is The Turbocharger Boost Control Position Sensor Located

The turbocharger boost control position sensor is typically located directly screwed or bolted into the turbocharger housing. The sensor is can also found at the wastegate actuator.

Troubleshooting Of P2563 code On 6.4 Powerstroke

  1. Use a scan tool to retrieve the specific error code brought about by the check engine light.
  2. Check the wiring and connections of the sensor
  3. Clean the sensor to ensure smooth movement
  4. Replace the turbocharger boost control position sensor
  5. Conduct a road test to assess drivability issues
  6. Repeat the process if the problem persists

Codes Related To 6.4 Powerstroke P2563 Code

FAQ About P2563

Is P2563 Serious? Is It Possible To Drive With DTC P256?

Although it is possible to drive the vehicle with a P2563 code, it is not recommended. This is because the performance of the turbochargers affects engine performance, fuel efficiency, and power output causing problems with acceleration and towing heavy loads.
