Drive with caution — fix soon.
This code means the voltage signal from turbocharger boost sensor B is higher than expected, often caused by a short to voltage, a wiring fault, or a failed sensor. A genuine overboost condition can also set it. It's a common turbo code and is usually fixed by repairing the wiring or replacing the boost sensor.
$100 – $400
Varies by vehicle and root cause.
Usually for short trips, yes, but go easy. The car may limit power or feel jumpy, so avoid hard acceleration and towing and have it checked soon.
Expect roughly $100 to $400. Replacing the sensor is the cheaper route, while diagnosing a wiring short or overboost issue adds labor cost.
It's moderate. It usually won't strand you immediately, but a real overboost or ongoing power loss can stress the turbo, so address it promptly.
It can. A high reading is sometimes a true overboost from a stuck wastegate or boost control fault rather than just a sensor problem, so a proper diagnosis is worthwhile.
