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.

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?

Why not post the actual code?

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

Jerry Bransford 11-28-2013 09:58 AM

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.
