I didn't replace either of them. I've had the car for about a month, and it
ran fine until this. I figure it has to be something electrical, though.
It was running fine when I parked it. Then, when I went to leave, it
wouldn't start.

After I replaced the TPS, I unhooked the battery to reset the codes. Since
then, I haven't had any codes except 12 and 55.
