I can help you with what it says in the workshop manual:
-Using the manufacturer approved diagnostic system check datalogger signal, Mass Air Flow Sensor 2 Voltage(0x0503)
-Check mass air flow sensor circuit fuse. If fuse fails, may see DTCs P0103, P010C and P250C
-Check air cleaner element is free from restriction
-Check for blockage in air intake system
-Refer to the electrical circuit diagrams and check mass air flow sensor bank 2 circuit for high resistance, open circuit, short circuit to ground, short circuit to power
-Check and install a new mass air flow sensor bank 2 as required. Refer to the warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module/component
