Drive with caution — fix soon.
This code means the engine computer detected high voltage (or an open circuit) in the wastegate solenoid circuit A. With the signal stuck high or interrupted, the solenoid can't regulate boost correctly, which can lead to over-boosting or erratic performance. It's commonly fixed by repairing open or damaged wiring, replacing the solenoid, or cleaning the connector.
$150 – $450
Varies by vehicle and root cause.
For short trips, usually yes, but avoid hard acceleration. A high signal can cause over-boosting, which can stress the engine. Have it diagnosed soon to be safe.
Repairs usually run $150 to $450. Fixing open or corroded wiring is cheaper, while replacing the solenoid costs more. Diagnostic time is normally included.
It's a moderate issue. The car will still run, but over-boosting from a stuck-high signal can damage the turbo or engine over time. Fixing it promptly is recommended.
'High' means the computer sees high voltage or an open circuit in the solenoid wiring, often from a broken wire or failed connector. This blocks proper boost control. A technician can test the circuit to find the exact fault.
