P2563 — Turbocharger Boost Control Position Sensor Circuit Range/Performance
Moderate severityWhat it means
P2563 is stored when the engine control unit sees a fault involving the turbocharger boost control position sensor circuit. This sensor reports the position of the boost-control actuator (wastegate or vanes) so the control unit can manage boost accurately; a fault makes boost control unreliable. A “range/performance” fault means the value is present but implausible — it does not agree with other sensors or expected conditions.
Common symptoms
- Readings that drift or disagree with related sensors
- Loss of power or limp mode
- Boost that is too high or too low
- Check engine light
Likely causes
- Drifting, contaminated or aged sensor
- A mechanical issue skewing the reading
- A faulty boost-control position sensor or actuator
- A wiring/connector fault or a sticking mechanism
What to check first
- Cross-check the reading against related sensors in live data on a cold start
- Compare commanded vs actual actuator position in live data
- Inspect the sensor/actuator linkage and connector
Can you keep driving?
Often drivable with reduced power, but uncontrolled boost can stress the turbo — diagnose soon.
Frequently asked questions
What is the most common cause of P2563?
The most likely cause is: Drifting, contaminated or aged sensor. Several other faults can set P2563 as well, so confirm the real cause with live data and the checks above before replacing any parts.
Can I just clear P2563 and keep driving?
Clearing P2563 with an OBD2 scanner turns the warning light off, but if the underlying fault has not been repaired the code will usually come back within a few drive cycles. Fix the cause first, then clear the code to confirm the repair worked.
How serious is P2563?
P2563 is a moderate-severity code. The car is often still drivable, but have it diagnosed soon — the underlying problem can get worse and it may fail an emissions test.
