Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected too high a voltage signal on the 'B' wastegate solenoid circuit, which controls turbocharger boost pressure. It often points to a wiring short to power, a bad solenoid, or a connector problem rather than the turbo itself. Repairs usually involve inspecting and repairing the wiring and connector, then replacing the solenoid if it has failed.
$150 – $500
Varies by vehicle and root cause.
For short trips, usually yes, but you shouldn't rely on it. A faulty wastegate can cause power loss or overboost that may damage the turbo or engine, so drive gently and get it checked soon.
Most repairs run from about $150 to $500. A simple wiring or connector fix is on the low end, while replacing the wastegate solenoid with labor is higher.
It can be. Because it affects turbo boost control, an unchecked fault can lead to overboost and engine damage. It's worth addressing promptly rather than ignoring.
The wastegate solenoid regulates how much exhaust bypasses the turbo, controlling boost pressure. If it sends a faulty high signal, the computer can't manage boost correctly, leading to power loss or risky overboost.
