P0241 — Turbocharger Boost Sensor B Circuit Range/Performance
Drive with caution — fix soon.
What P0241 means
This code means turbocharger boost sensor B is reporting a pressure that doesn't match the engine's actual operating conditions. It often comes from a faulty sensor, a boost leak, a blocked sensor hose, or wiring issues. It's a common turbo code that's usually repairable without major engine work, often by cleaning or replacing the sensor.
Common symptoms
- Check engine light is on
- Loss of power or weak acceleration
- Engine may enter reduced-power (limp) mode
- Poor fuel economy
- Hesitation or surging under load
Common causes
- Faulty turbocharger boost sensor B
- Boost leak in the intake or turbo system
- Clogged or cracked sensor pressure hose
- Damaged wiring or loose sensor connector
- Actual turbocharger underboost or overboost
Typical repair cost
$100 – $400
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0241 code?
For short trips, usually yes, but ease off the throttle. The car may feel weak because it limits power to protect the turbo, so avoid hard driving and towing and get it checked soon.
How much does it cost to fix a P0241 code?
Typically $100 to $400. A sensor or hose replacement is cheaper, while finding a boost leak or wiring fault takes more diagnostic time.
Is a P0241 code serious?
It's moderate. It usually won't strand you immediately, but driving with it can mean ongoing power loss and turbo strain, so don't let it linger.
What causes a range/performance fault on the boost sensor?
It usually means the reading is technically present but wrong for the conditions, often from a boost leak, a clogged hose, or a sensor that's drifted out of spec rather than a total electrical failure.
