P2563 on Chevrolet
Turbocharger Boost Control Position Sensor "A" Circuit Range/Performance
P2563 on Chevrolet vehicles indicates turbocharger boost control position sensor "a" circuit range/performance. Au7o has documented this code across 1 Chevrolet model — most commonly on Sonic. This generic powertrain code sets when the PCM/ECM detects that the signal from the turbocharger boost control position sensor (which reports the position of the variable-vane or wastegate actuator) is out of the expected range or does not respond as commanded. It indicates the module cannot confirm the turbocharger boost control mechanism is moving to the position it requested, often pointing to a vane/actuator position-sensing or boost-control fault. Typical repair costs on Chevrolet range from $50 to $1,800, depending on the specific model and root cause.
Common Causes of P2563
- •Faulty turbocharger boost control (vane) position sensor
- •Sticking or seized variable-vane mechanism or wastegate actuator
- •Failing turbocharger boost control solenoid/actuator
- •Wiring or connector faults (open, short, corrosion, chafing) in the sensor circuit
- •Carbon buildup binding the turbo vanes (common on diesels)
- •Poor PCM/ECM ground or, rarely, a failed control module

- Turbocharger Wastegate Actuator Pivot Pin Wear and Missing Retaining Clip (Underboost)2012-2020
The 1.4L turbo's wastegate is operated by an external actuator whose arm pivots on a small pin retained by a light clip. The pin wears and the clip can work its way off entirely, letting the wastegate flapper drift open when it should be closed. Boost bleeds off, the ECM sees a target it cannot reach, and P0299 underboost sets - often with an audible rattle from the exhaust housing at light throttle. Owners on Sonic Owners Forum have documented the missing-clip failure specifically, and the wear condition is described as showing up from roughly 15,000 miles onward. This is routinely misdiagnosed as a completely dead turbocharger and quoted as a full turbo replacement. On 2017-2018 Sonics GM opened special coverage N232395330 extending turbocharger coverage to 10 years / 120,000 miles for turbo failure.

What does P2563 mean on Chevrolet?▼
P2563 stands for "Turbocharger Boost Control Position Sensor "A" Circuit Range/Performance." This generic powertrain code sets when the PCM/ECM detects that the signal from the turbocharger boost control position sensor (which reports the position of the variable-vane or wastegate actuator) is out of the expected range or does not respond as commanded. It indicates the module cannot confirm the turbocharger boost control mechanism is moving to the position it requested, often pointing to a vane/actuator position-sensing or boost-control fault. On Chevrolet specifically, this code is documented across 1 model.
What causes P2563 on Chevrolet vehicles?▼
Common causes on Chevrolet: Faulty turbocharger boost control (vane) position sensor, Sticking or seized variable-vane mechanism or wastegate actuator, Failing turbocharger boost control solenoid/actuator, Wiring or connector faults (open, short, corrosion, chafing) in the sensor circuit, Carbon buildup binding the turbo vanes (common on diesels).
