What does code P227C mean?

Q: What does code P227C mean?

Barometric Pressure Sensor C Circuit Low. P227C means the engine computer has detected an abnormally low voltage signal from the Barometric Pressure Sensor C circuit, which is used to measure atmospheric pressure for fuel and boost calculations. The computer compares the sensor signal against expected limits and sets this code when the voltage stays below the calibrated threshold for a set time.
