What does code P00FB mean?

Q: What does code P00FB mean?

Turbocharger Outlet Pressure Sensor A Circuit High. P00FB means the engine computer has detected an abnormally high voltage signal on the circuit for Turbocharger Outlet Pressure Sensor A, which is the sensor that measures boost pressure at the compressor outlet. The computer expects the signal voltage to stay within a calibrated range, and a sustained high reading tells it the circuit is shorted to voltage, the sensor has failed, or the reference voltage is being applied where it should not be.
