P0250: Turbocharger/Supercharger Wastegate Actuator B High
What to do
Expect reduced power. Diagnose before extended driving.
What this code means
The second wastegate solenoid circuit is reading high — a short to supply or an open circuit. This completes the eight wastegate solenoid codes spanning P0243–P0250; read alongside P0234 and P0299, which describe what actually happened to boost as a result.
Likely causes
Start here
- Open circuit in solenoid wiring · moderate
- Wiring shorted to voltage · moderate
- Failed boost control solenoid · moderate
Less common
- Exhaust heat damage to sensor harness · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
