Drive with caution — fix soon.
This code means the engine computer detected low voltage (or a short to ground) in the wastegate solenoid circuit B. With a weak or grounded signal, the solenoid can't regulate boost, which usually shows up as a loss of power. It's commonly fixed by repairing shorted or corroded wiring, replacing the solenoid, or cleaning the electrical connector.
$150 – $450
Varies by vehicle and root cause.
For short trips, usually yes, but don't push it. The turbo can't control boost properly, so power may be limited. Drive gently and have it checked soon.
Most fixes range from $150 to $450. A wiring or connector repair is cheaper, while a new solenoid costs more. Diagnostic time is generally included.
It's a moderate concern. The car still runs, but long-term driving with poor boost control can wear the turbo. It's best to fix it before symptoms worsen.
'Low' means the computer sees low voltage in the 'B' solenoid circuit, often from a short to ground or a failing solenoid. This prevents proper boost control. A technician can determine whether it's wiring or the part itself.
