Default jeep still throws a P1398 code at me even after new CPS

from what i gather, the only other thing it could be is the PCM. is this correct or are there other things i should be looking at. i also replaced the TPS, not that that has anything to do with it but it was bad to. also when i did the on-off-on-off-on key thing, it gave me the codes, 12, 11, 42. i have 11 figured out. my battery died the other day. 12, im not sure if that could just be from turning the key on and off so many times without actually starting it. and 42 i found that it says something to do with the ASD relay or something with the fuel pump. my ? about code 42 is what do i look for and what has anyone seen gone wrong cause this code to show up? any help would be greatly appreciated.

thanks~

Any chance you've removed the distributor and reinstalled it lately?
