Mass air flow sensor; you could start by cleaning the air filter. I would remove the air filter & start the engine and see if that has any effect on the code presence.
Apparently bad fuel may also set this code; I also found this:
'To reset these you must start with the key off, press and hold 2 amber buttons on left, turn on key, an A appears in display. Press amber button once and a B will appear in the display, press and hold 2 amber buttons till display changes, then press button once so display says off, press button again and display goes blank. turn key off for a minute then code will be gone.'
Good luck! CODES SUK
