P0882 limp mode
 

I have a 2006 dodge stratus sxt 2.7. It has recently gone into limp mode. Gives code p0700 and p0882. I have replaced alternator, starter and battery. After installing new battery, it came out of limp mode. After sitting for a few days, the battery was dead. Recharged battery, now back to limp mode. Eatx fuse and relay are fine.
Also after removing front o2 sensor to replace starter, after putting o2 sensor back in... giving codes p0032, p0038, p0052 and p0058. Could this be a single short, multiple shorts, a ground issue or a bad pcm?
