I don't know if the corrosion is a common problem or if someting is wrong here too.
If the battery is dead (or almost dead because the alternator can't charge), yes, it could, but you should get the battery/charge light coming on in your instrument cluster (and that would not be the reason for a P0402). You might as well charge the battery while you are at it. Then put some grease (or anti corrosion) on the terminals. Terminal corrosion can happen to any vehicle/battery (and sometimes within 2 or 3 years old).
