Do you find the turbocharger or the pressure gauge to be faulty? Do you want to know more about the diagnostic procedure? Then keep reading further. The P2563 error code generally refers to the turbocharger boost control position sensor ‘A’ circuit. With the help of a turbocharger vane position solenoid, the boost from the turbocharge is controlled by the engine computer that is PCM. The PCM makes sure that the solenoid works accurately as needed by utilizing a turbocharger vane position sensor. P2563 error code might get stored in

the vehicle, if the turbocharger vane position sensor flops to send correct report back to the PCM.

This is a general type of diagnostic trouble code where the engine control module will carefully look after the variable geometry turbocharger electronic actuator. This error code signifies that the engine control module (ECM) has found an issue with the variable vane geometry turbo control. Either the position sensor may not lie within the specification or the performance of the vehicle may lie out of the specified range while the vehicle is being monitored.

What causes this problem with the Turbocharger Boost Control Position Sensor "A" Circuit Range/Performance?

• The signal circuit from the ground to the TBCPS sensor might be shorted.
• There might be an opening in the signal circuit to the TBCPS sensor.
• From the signal circuit to the TBCPS sensor, there might be a short in voltage.
• Most likely, you might find an opening either in the power or the ground at the location of TBCPS sensor.
• There is a possible chance for the TBCPS sensor to be malfunctioning.
• The powertrain control module might be malfunctioning and it is very rare.

1. Turbocharger boost control position sensor - Fixing the faulty turbocharger boost control position sensor can help to avoid the P2563 error code.
2. Turbocharger - The acceleration of the vehicle will be very slow if the turbocharger is faulty. Fix it quickly to avoid the P2563 error code.
3. Pressure Gauge - Excessive vibration can cause the pressure gauge to malfunction. Fix it as instantly as possible.
4. Engine Control Module - The engine control module is considered to be the brain of the engine management system. So, if your ECM is not functioning properly, then an immediate replacement is needed so that the system functions normally.
5. Powertrain Control Module - A faulty PCM can cause misfiring issues and the engine behaviour might also be erratic. If your vehicle is causing misfiring issues, then it is because of a faulty powertrain control module. Shop them from Parts Avatar at best prices online.

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2563 here:

Common Symptoms

• Malfunction indicator lamp will remain the same.
• Performance might be weak.
• The engine might not be willing to start as you accelerate.
• Reduced fuel economy.

Want to correct the Trouble Code P2563? Read these points mentioned below:

• The soot which is present in the turbo control system has to be made clean.
• The defective or damaged turbocharger control actuator assembly has to be quickly fixed.
• The malfunctioning turbocharger assembly has to be replaced.
• The electrical wiring harness or the connection to the control actuator has to be fixed or changed as soon as possible.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2563 code to be stored:

• The mechanic will scan the code and then document every of these codes which are available in the ECM and then check for the freeze frame data for any defects.
• The soot which is present in the turbo and the exhaust system has to be cleared and then the code has to be retested.
• The resistance of the actuator has to be carefully measured by following a pinpoint test for further specifications.
• Visually inspect for shorted or broken wires in the harness.
• For further diagnostic procedure of the turbocharger, the mechanic has to follow the manufacturer’s pinpoint test.
• The mechanic will perform every of the diagnostic procedure in a sequential manner.
• Once the diagnostic procedure is done, the mechanic has to clear the codes and test-drive the vehicle to see if the error code shows up again.
• This will eventually help the technician to realize as to where the error code was stored in the vehicle.

Common Mistakes When Diagnosing the P2563 Code

• Failing to address the P2563 error code before other codes. This error code can cause other trouble codes which is linked to the turbo.
• Forgetting to clear the error codes of the ECM once it is fixed and testing them again to check the fix.
