Turbocharger Boost Control Position Sensor A Circuit
What it means
P2562 means the ECM has detected an electrical fault in the circuit for turbocharger boost-control position sensor "A," which reports the position of the wastegate or variable-vane mechanism. Without a trusted position signal, the ECM usually limits boost, so the car may feel down on power or drop into limp mode. Common causes are the sensor itself, its wiring, or a binding actuator.
Can I keep driving? Usually yes, but expect reduced power or a limp mode — the ECM often limits boost when it can't trust the position sensor.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

Common symptoms
What you'll notice
- Check-engine light on
- Noticeable loss of power or sluggish acceleration
- Reduced or erratic turbo boost
- Possible limp/failsafe mode
Common causes
Most likely first
- Faulty turbocharger boost-control position sensor (sensor 'A')Likely
- Open, shorted, or high-resistance wiring in the sensor circuitCommon
- Corroded or loose sensor connectorCommon
- Binding or stuck boost-control actuator/vane mechanism affecting the sensorLess often
- Faulty ECM/PCM input (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and note the reported boost-control position.
- Inspect the position sensor connector and wiring for damage, corrosion, or looseness.
- Check the signal, reference, and ground circuits for opens or shorts.
- Verify the boost-control actuator/vanes move freely and aren't binding.
- Replace the sensor or repair the wiring as needed, clear the code, and road-test for normal boost.
