Drive with caution — fix soon.
This code means the wastegate solenoid (circuit A) is working, but its performance is outside the expected range, so boost pressure isn't being controlled accurately. The cause is often a sticking solenoid, a leaking vacuum hose, or a wastegate that isn't moving freely. It's typically fixed by cleaning or replacing the solenoid, sealing vacuum leaks, or freeing up the wastegate actuator.
$150 – $500
Varies by vehicle and root cause.
Short trips are usually fine, but don't make a habit of it. Since boost control is off, drive gently and avoid heavy acceleration. Have it diagnosed soon to keep the turbo healthy.
Repairs typically fall between $150 and $500. A simple vacuum leak or connector cleanup is cheaper, while replacing the solenoid costs more. Diagnostic fees are usually part of that estimate.
It's a moderate issue. The car remains drivable, but poor boost control can stress the engine and turbo if left alone. Fixing it promptly is the smart move.
Range/performance means the 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 completely dead component. A technician can confirm the exact cause with a quick test.
