This value is hexadecimal, and represents the OBDII DTC. 
The upper 2 bits determine which letter it is (0b00 = P, 0b01 = B, 0b10 = C, 0b11 = U). The remaining 14 bits, when viewed as hexadecimal are the number part of the code. 
e.g. 0x2A00 = P2A00 = "Wideband 1 Sensor Failure. See Wideband O2 1 channel."
