04 yukon ground location

[hotwrench500]

Hi, I am a new member and wanted to say hello. Also was looking for info on ground locations on 04 yukon slt 5.3 auto. I have multiple codes (b-2365; p-0171; p-0174; p-0101; u-1026; u-1041; u-1000;) and believe it to be a bad ground that is common to set P, B and U codes. Thanks for the help. I have searched several pages of past topics and did not see anything relevent.
