You need to cross connections on the diagnostic connector with the ignition off and the light will flash the codes out. There is a picture on here somewhere of which ones to cross but i'm fairly sure it's the 3rd and 5th up. But check first :y

Edit:Must type and post links faster :D

12 is the start of the sequence. 71 is the air temp. sensor. Any odd temp readings on your dash display :question

Its a 2 pin item mounted in the air duct between the air fliter (large box front left of the engine bay) and the throttle body.

There is also a 4 pin connector which is the MAF, you want the 2 pin one  :y

Check the wiring and make sure its connected ok
