P0247 — Turbocharger Wastegate Solenoid A High
Drive with caution — fix soon.
What P0247 means
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.
Common symptoms
- Check engine light is on
- Excessive or surging turbo boost
- Loss of power or erratic acceleration
- Engine may enter reduced-power (limp) mode
- Reduced fuel efficiency
Common causes
- Open circuit in the solenoid wiring
- Faulty wastegate solenoid (circuit A)
- Corroded, loose, or disconnected connector
- Damaged wiring harness near the turbo
- Short to voltage in the control circuit
Typical repair cost
$150 – $450
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0247 code?
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.
How much does it cost to fix a P0247 code?
Repairs usually run $150 to $450. Fixing open or corroded wiring is cheaper, while replacing the solenoid costs more. Diagnostic time is normally included.
Is a P0247 code serious?
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.
What does 'high' mean in a P0247 code?
'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.
