Codes 2188 & 2190 - Short Trim

After I repaired a camshaft magnet issue the CEL did not go away so I checked the codes again using GoPoint. I got 2 codes for Short Term Trim and I have no clue what to do, short of going to the dealer. Code 2188 - Short Term Trim Bank 1 and 2190 Short Term Trim Bank 2. The analysis told me Short Term Trim for Bank 1 is -10% and -8% for Bank 2. the Long Term Trim is 9% and 11% respectively. Help!!
