P2563: Turbocharger boost control position sensor A range/performance
The sensor reporting the position of the turbo’s boost control mechanism gives implausible values. Usually a sticking actuator or vanes, or the sensor.

What P2563 means
Many turbochargers control boost by moving a set of vanes or a valve with an actuator. The position sensor tells the ECU where that mechanism is. The ECU sees that the measured position is not believable or does not follow what it asked for. Which sensor is A is set by each manufacturer.
Most common causes
- Variable geometry vanes sticking with carbon
- Faulty turbo actuator (electric or vacuum)
- Actuator or sensor connector loose or corroded
- Position sensor out of adjustment or faulty
- Split vacuum hose or faulty boost control solenoid
Symptoms
- Engine warning light on
- Loss of power or limp mode
- Boost comes in unevenly or not at all
- Sometimes more smoke under acceleration
Can you drive with P2563?
With care You can drive with care, but get it to a garage soon. The car will often go into limp mode with little power, which is awkward when overtaking or joining fast roads.

How to check it
If your scanner shows it, compare the commanded and actual turbo actuator position live while accelerating. A big gap or sudden jumps point to sticking vanes or an actuator that is not responding.
How to read and clear P2563 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P2563 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P2563?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P2563 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
