P2563Turbocharger Boost Control Position Sensor A Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2563 means the position feedback of the turbocharger boost control actuator - variable vanes or wastegate - does not match the commanded position, without an open or short being reported. GM's 2009 Duramax diesel table sets it when vane position differs from target by 15 % or more for 5 s (Type B, warning light after two trips). VW's 2014 Passat book treats a position signal above 4.5 V or below 0.3 V as implausible on the 2.0 L TDI (CKRA), and VW bulletin 21-15-06 links P2563 on 2.0 L TDI engines to kinked vacuum hoses, a leaking vacuum diaphragm or a broken adjustment stud on the turbocharger. P2562/P2564/P2565 are circuit faults, P2566 an intermittent signal. Boost is often limited, so power drops noticeably.
- What you may notice
- Noticeable loss of power, limp mode
- Check engine light
- Underboost code P0299 stored at the same time
- Likely causes
- LikelyKinked, twisted or leaking vacuum hose to the boost actuator
- PossibleLeaking actuator diaphragm or sticking vanes
- RareBroken or missing adjustment stud, actuator travel out of tolerance
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
