9 is the cylinder position sensor(cyp) its either defective or not pluged in maybe cleaning it can work not sure...its inside the dizzy...and as for 14 thats the intake air control valve(iacv) that is the plug behind the intake mani...take it out and clean it...unplug the negative from the battery for 10sec and then if it stills trows 14 then the iacv is bad
