For the p0031 codes check your efi main relay and switch with a like relay if not that then check resistance in O2sensor which shold be bank 1 sensor1-priorto converter whichever cylinder is number 1side. Code 1201 a pro shold look at this because it can be a broken harness or pinched harness going to abs unit or a few other things.
