Drive with caution — fix soon.
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.
$100 – $400
Varies by vehicle and root cause.
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.
Typically $100 to $400. A sensor or hose replacement is cheaper, while finding a boost leak or wiring fault takes more diagnostic time.
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.
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.
