Review: Perfect fit for Oxygen sensor error code P0031 - Perfect OEM fit. Fixed a check engine light. In fact the cable is about 4 to 6 inches longer allowing you to place it and secure it even better than the original part. Please be aware of the right part to replace depending on the code you get. For Jeep Liberty 02/06 you have 4 Oxygen Sensor one before and after each Catalytic Converter on both Catalytic identify as Bank 1 for the Driver side and Bank 2 for the Passenger Side. There is another after burn Catalytic Converter that goes to te exhaust (parts not mention OEM brand is NTK for Direct Fit. In my case, here are the part numbers and placement for Jeep Liberty MY 02/06 according to the error codes P0031 read in my ODB II. To fix this you’ll need the right part since the position and length of the cable of the sensor are different. In this case P0031 was related to a “HOS2 Heater Control Circuit Low Bank Sensor 1”. In this Case B1S1 stands for Block 1 Sensor 1z With that info I was able to buy the part, but needed to know which one was Bank 1 or Bank 2 as well as Low or High. Hope this info help you clarify which one to replace. BANK 1 = Driver Side /LEFT PART # PLACEMENT 2139 B1S1 (Before Catalytic Driver side) 23141 B1S2 (After Catalytic Driver side) BANK 2 = Passenger Side/ RIGHT PART # PLACEMENT 23138 B2S1 (Before Cat.
