P0249 — Turbocharger Wastegate Solenoid B Range/Performance
Drive with caution — fix soon.
What P0249 means
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.
Common symptoms
- Check engine light is on
- Boost pressure runs too high or too low
- Sluggish or uneven acceleration
- Whistling or hissing from a vacuum leak
- Reduced fuel economy
Common causes
- Sticking or partially failed wastegate solenoid (circuit B)
- Vacuum hose leak or restriction
- Wastegate actuator binding or out of adjustment
- Worn or corroded electrical connector
- Carbon buildup affecting the wastegate
Typical repair cost
$150 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0249 code?
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.
How much does it cost to fix a P0249 code?
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.
Is a P0249 code serious?
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.
Why does P0249 mention range/performance?
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.
