Nooooooo You got it wrong! 31 Is the code that tells you your CO-DRIVER is on board!! I have been searching like many others, for a fix other than removing the light! That one you could be stuck with for a spell.

12 means the ecu has been reset within 50 key cycles 21 o2 is not cycling like it is supposed to be...replace it 31 check all hoses for clogs, all wiring to make sure no breaks at the plugs, purge solinoid may very well be bad..you are correct 12 = end of codes
