Bank 1 vs. Bank 2 o2 sensor location

What is the location of #1 Cylinder on a 2004 4.0l. Is it the drivers side or the passenger side of the engine. I have a o2 sensor code Bank 1 sensor #2.

Both banks are located on the driver's side. Bank one is towards the front of the engine.

That would be helpful. I have a 2006 Rubicon with code P0137 indicating Downstream, Front Manifold - Bank One, Sensor Two; Physically located towards the front of the vehicle after the mini-catalytic converter.

Pictures would be helpful as I am unsure where to look. TY.

Bank 1 and bank 2 turned me down after buying my 5th TJ in 8 years for upgrades!

Follow the exhaust down from the #1 cylinder at the cylinder head. #1,2,and 3 will come together into one pipe. Follow that pipe down through the "mini" catalytic converter. The first sensor that you come to after that converter is the one you're looking for.

My RHD TJ - Savvy equipped... And loving it!

I drive on the right side, what's wrong with you?

Just open the hood and take a look. Pretty hard to miss. Picture is not going to show you anymore than what you will see when you take a look. Not real confusing.

You better open your hood and look. You don't have a V6 you have an inline 6. The cyls are numbered 123456 from front to rear.

Bank 1 is fed by cyls 1,2and 3 and sensor 2 is after the cat in #1 bank.

While this explanation helps to clarify, I took some pics.

I am looking for: P0137 indicating Downstream, Front Manifold - Bank One, Sensor Two; Physically located towards the front of the vehicle after the mini-catalytic converter.

These two were the furthest away, the one on the left being towards the front.



Then there were these 2 closer to the bottom of the Jeep. This one being closer to the front:



This one being closer to the rear:

The one on the left is bank 1, on the right is bank 2. Both upstream.

Bank 2 downstream. Hope that helps.

ok so...i realize the factory manual uses the designations 1/1, 2/1,1/2,2/2 for the O2 sensors, however, the parts store only labels the sensors as front upstream, rear upstream, front downstream, rear downstream. am i correct in assuming that 1/1 is F/U, 2/1 R/U, 1/2 R/U, 2/2 R/D?
