What does code P0250 mean?

Q: What does code P0250 mean?

Turbo/Super Charger Wastegate Solenoid 'B' High. P0250 is a generic powertrain code indicating that the engine control module (ECM) has detected an abnormally high voltage on the wastegate solenoid 'B' control circuit, which usually points to an open circuit, a short to voltage, or a failed solenoid. The ECM commands the solenoid to regulate boost pressure, and when the feedback voltage exceeds the expected range, it sets this code and may limit boost to protect the engine.
