Drive with caution — fix soon.
This code means the computer has detected a general fault with turbocharger boost sensor B, which on many engines monitors a second turbo or a different point in the intake. It usually points to a faulty sensor, wiring or connector problems, or a boost-related fault. It's a fixable turbo code, often resolved by replacing the sensor or repairing the circuit.
$100 – $400
Varies by vehicle and root cause.
Short trips are usually okay, but the car may limit power and feel weak. Avoid hard acceleration and towing, and get it diagnosed soon.
Most repairs run $100 to $400. A sensor replacement is on the lower end, while wiring repairs or chasing a boost leak adds to the bill.
It's moderate. It usually won't leave you stranded right away, but continued driving with reduced power isn't ideal, so don't put off the repair.
Sensor B is a second boost pressure sensor, often for a second turbocharger or a different spot in the intake system. A scan tool and the wiring diagram help pinpoint which one it is.
