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 this same explanation and whether it’s confirmed, pending or permanent.

With Free you read this code with its short description for nothing, and clear it if the engine stores it over standard OBD. With Pro you get the full explanation, how the car was running when it was logged (revs, temperature, load) and clearing in every control unit.

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 the ITV. It’s all in how to read and clear fault codes and in the ITV and OBD.

P2563 is a generic code, so it means the same on any make, for example on Abarth, Citroën, Cupra, Hyundai, Mini, Seat. See what Final OBD does on your car in makes and models.

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.
