Drive with caution — fix soon.
This code means the wastegate solenoid for circuit B is working, but its performance falls outside the expected range, so boost pressure isn't controlled accurately. The cause is often a sticking solenoid, a vacuum leak, or a wastegate that isn't moving freely. It's typically fixed by cleaning or replacing the solenoid, sealing vacuum leaks, or freeing the wastegate actuator.
$150 – $500
Varies by vehicle and root cause.
Short trips are usually fine, but don't rely on it. With boost control off, drive gently and avoid hard acceleration. Have it diagnosed soon to keep the turbo healthy.
Repairs typically fall between $150 and $500. A vacuum leak or connector cleanup is on the lower end, while replacing the solenoid costs more. Diagnostic fees are usually included.
It's a moderate issue. The car stays drivable, but poor boost control can stress the engine and turbo if ignored. Fixing it promptly is recommended.
Range/performance means the 'B' solenoid is responding, but not within the limits the computer expects. This often points to a sticking part or a vacuum leak rather than a dead component. A technician can confirm the cause with a quick test.
