The codes are 13, 45, 46, & 61.
I've never seen 13 but I'm pretty sure it's just a marker to begin the sequence. 61 means it's the end.
45 and 46 are both for the MAP sensor low and high input respectively. That means your voltage signal from the MAP sensor is all over the place or nonexistent at times. The sensor itself would be really hard to damage so I suspect the wiring harness is bad. It's a very common problem.
I would replace it with the one at the link I posted earlier. It's really easy and comes with everything you need.
