Complete list of Oxygen Sensors for my 4.0 TJ
 
I've got an intermittent check engine light on my 2003 Rubicon with the 4.0L. It says a specific O2 sensor, but with 90k miles I'd like to replace them all. How many do I have? Anyone have the quantity and part numbers for each, especially Bosch?

Amy recommendations for a particular brand besides Bosch?

Thanks in advance.

I reccomend NTK brand sensor
Bosch don't seem to work well with jeeps for some reason

NTK Part # 23139 NTK OE Type
Upstream Front; NTK is the OE Mfg

NTK Part # 23138 NTK OE Type
Upstream Rear; NTK is the OE Mfg

NTK Part # 23142 NTK OE Type
Downstream Front; NTK is the OE Mfg

NTK Part # 23141 NTK OE Type
Downstream Rear; NTK is the OE Mfg

Advance Auto Parts us currently offering a rebate on NTK, Denso and other oxygen sensors. If you order online, you can save in the vicinity of 40% with a discount code. Save an additional 10% if you link through a Discover card.

Personally, I would not replace a downstream oxygen sensor unless there was a DTC. They don't have much affect on anything that matters.

What's a DTC? I think I got bank 1 sensor 2 as the code, wouldn't that be downstream?

4 total.

Why not post the actual code?

Which part # coincides with error code P0135, "bank 1, sensor 1"?

Bank 1 is at the front of the engine, Bank 2 is at the rear of the engine.

Sensor 1 is above the pre-cat, Sensor 2 is below the pre-cat.

Do you have photos of where the 02 sensors are located? I need to locate Bank 1 sensor 2

I have s similar issue. I just got both ntk upstream sensors from rock auto (great price) but the part is listed for cylinders 1-3 and 3-6, my guess is bank one would be 1-3. Is that correct? Thanks

Sorry to bring this thread back, I recently taken possession of a 2000 4.0 Tj and I currently have codes P0135 and P0141. I erased them and they came back, what is the likely hood that both O2 sensors on the same bank would take a dump at the same time? Should I consider replacing all 4? Do these sensors have a life span? I have 122k miles on my Tj.

Thanks for your help
