BANK 1 SENSOR ONE 1ST O2 sensor from cylinder #1 -2 -3 (p side )
bank 1 sensor two 2nd O2 sensor from cylinder #1 -2-3 (P side)
bank 2 sensor 1 is the 1st O2 sensor from cylinder #4-5-6 (d side )
bank 2 sensor 2 is the 2nd O2 sensor from cylinders # 4-5-6 (D side )
make sure u have check and replace the correct sensor
these are the other possibility s
DTCs P1130, P1131, P1132, P1150, P1151 Or P1152: Upstream HO2S Not Switching Continuous Memory DTCs P1130 and P1150 indicate when an HO2S fails to switch due to a circuit or fuel at or exceeding a calibrated limit. KOER and Continuous Memory DTCs P1131,
P1132, P1151 and P1152 indicate a concern when fuel control system does not detect HO2S switching for a calibrated time. DTCs P1130, P1131 and P1132 refer to HO2S-11. DTCs P1150, P1151 and P1152 refer to HO2S-21.
Possible causes for these faults are:
Excessive fuel pressure, leaking or contaminated fuel injectors, leaking fuel pressure regulator, low fuel pressure or engine running out of fuel or vapory recovery system fault. Induction System
Air leaks after MAF sensor, vacuum leaks, PCV system or improperly seated engine oil dipstick.
Leaking gasket, stuck EGR valve or leaking diaphragm or EVR.
Engine oil overfilled, cam timing, cylinder compression or exhaust leaks before or near HO2S.
