2 is an accelerator sensor problem. this problem can come up when you over rotate the pot by flooring the pedal with the floor plate removed but it can be an open wire. this can also come up when you have the pedal pot unplugged.
14 is idle potentiometer problem, can be over rotation. if you haven't done anything to cause these codes you may have controller issues. look at the controller last, they
r a r e l y e v e r fail. these codes will clear when the problems are cleared and the key is cycled
