O2 sensor fault

[multihull]

I have a JKUR 2011 and the Engine management dash light is on and an error code P2245 .
This is the "O2 Sensor Reference Voltage Circuit Low, Bank 1 Sensor 1"
Which is the Bank 1, Sensor 1 on the exhaust system and where do I find it? Does someone have a picture from the Dealer's Service manual they can send me or describe where it is as shouldn't be a hard job to replace as these sensors do fault out.

Also I have just moved across from to the Rubi from my Commander and are looking for a copy of the full JK 3.8 service manual and DTCs. Can you point me in the direction of where to down load a copy.

Thx

I've found this on line which may help anyone in the future with a similar issue.

Before i went out and bought a replacement O2 sensor I thought I'd swap the R/H sensor for the L/H one and see what happens. I cleared the code, started the car and within 3 minutes "Bing" the EML comes on again. I checked the code and it's states the same sensor is playing up. Strange as I just did a swap.
Any ideas what the cause may be. I can't hear or see any signs of a leaking manifold.
Should I change all 4 sensors but this sounds like an expensive experiment.
I look forward to any advice.

As previously mentioned I went back and worked on a process of elimination to try and find why my Petrol 2011 JK Wrangler Rubi has error code P2445 which is a diesel error code. I swapped the L/H top and bottom sensor to the R/H and vica versa. I then cleared the code and started the car before i even had a chance of reversing out of the drive the same code popped up again. Hmmmm, so this can't be a sensors. Then this morning I thought I'd check the earthing from the battery to the engine block as suggested on another USA forum as the Wranglers can have issues with earthing.
I started at the battery where the previous owner had installed a twin battery system. The 1st job was I didn't like the Mopar pressed metal negative battery terminal which had too many wires crammed onto it so I changed it for a solid cast terminal with a longer accessories post and also found that a positive connection to a Voltage Sensitive Rely (VSR) was loose as well. I did these fixes and thought I'd check the system before going all out and putting a bigger negative cable to the engine block and YEE-HAA the error code has disappeared, even after a good drive it hasn't reappeared.

So if you have error code P2445 come up on a Petrol JK Wrangler check the wiring.

Bugger, 2days later and the code came back. Back to square one and looking for advice and help to get rid of this annoying Engine Management Light and error code.

It turned out to be two issues.
= I replaced all 4 sensors and bingo the MIL light on the dash went off. Now this is strange as the P2245 code is meant to be for a diesel JK not a petrol. Anyway a word of advice just change the O2 sensors. I bought a second hand set from the wreckers to save dollars for the test. I was apprehensive about spending big dollars for parts when the code was incorrect.
- I found the Bank 2 (L/H side) sensors cables had had a bad repair after being melted . I had to do a professional repair with correct size wire and solder and heat shrink and all is prefect now after 2,000 plus km of testing. Mind you the previous owner had had a repair done by a well know Jeep work shop in Melbourne.

Problem solved and very happy,
