Always diagnose and repair DTC's in the order they appear on the scan tool. After the repair, clear the DTC's, and complete a drive cycle. If more DTC's show up, repeat the procedure for each DTC as they appear.
The P1133 is a problem with the passenger side oxygen sensor. At 122,000 miles, all 3 oxygen sensors are overdue for replacement. If they haven't been replaced yet, replace them, clear the DTC's and complete a drive cycle. Post your results.
