Daughter's 98 v6 throwing code P1151

Daughter's CEL came on last night. This morning she told me it ran rough/slow while getting up on freeway. Had her take it to Autozone and received P1151 code. Was told it is o2 sensor. Any help on which one and/or other possible problem/reason for code? Thanks, Nelson
