P0250 Code: Turbocharger Wastegate Actuator B Circuit High
🟠 Moderate severity · drivable
Drivable, but the boost control circuit is faulty — avoid hard acceleration until fixed.
What P0250 means
The voltage or current in the wastegate actuator B circuit reads higher than expected. This is usually a wiring short to power or a faulty actuator, and it keeps the computer from controlling boost pressure.
Symptoms
- Check engine light is on
- Loss of power
- Possible overboost
- Poor acceleration
Common causes
- most common: Wiring shorted to power in the actuator circuit
- common: Faulty wastegate actuator or solenoid
- rare: Faulty engine computer (PCM)
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Repair wiring shorted to power | Mechanic | $50–150 |
| Replace the wastegate actuator or solenoid | Mechanic | $100–300 |
