Hi Everyone. I am a new owner of a 92 Range Rover County LSE. It is pained camo (leaves and all) and so far needs work hear and there. I am very happy to find the forum as it is a wealth of info that I am already using. I learned from the forum how to read the codes on the OBD system and found the check engine lite is due to the right O2 sensor (code 45). I do not have any manuals or service books yet and would love to know where the O2 sensors are (I think I found them but not sure) and also how tough is it to replace them?

Thanks everyone, and again GREAT forum. Total Rand Rover fan now :D

The 02 sensors (there are two of them on the '92 RRC) screw into sockets in the cats (catalytic converters), located one in each side of the Y pipe.

First, I'd love to see pictures of your camouflage paint job. My wife and I have pondered a camo paint job since we got our Range Rover three years ago.

Second, the oxygen sensors don't screw into the catalytic converters directly, but into the inlet pipes between the exhaust manifolds and the cats. They are just inches ahead of the cats, one per side.

Welcome to the forum. I've found it very helpful over the years.

Hello all. I am need of oxygen sensors for my 92 County LSE. I have found them ranging in price from 27.00 to 420.00. Does anyone know precisely what I need and is this a DIY job?

unplug, unscrew. screw in the new ones and plug in.

As far as what you need simply contact your local parts house like NAPA or call Atlantic British.

I used a large adjustable wrench to unscrew mine as they were pretty tough to loosen. Watch your hands/knuckles! As for unplugging them, when I did it it was a pain in the butt.

As for order: there might be two ways to do it: Plug the new one in first, then screw it in - OR - screw in the new one first, then plug it in. I plugged it in first, then screwed it in.

The left one (sitting in the driver seat), I followed from the sensor up about 12-14 inches up into the engine bay - after unplugging while under the car - i found it easier to get up and just reach down into the engine bay, pull the loose end and plug the new O2 sensor in - then dropped it down. Got back under the car and instead of starting to screw it into the hole - I pretwisted (unscrewing direction) the O2 sensor a good many times - and then while preloaded, srewed it into the hole. This made it easier as I plugged mine in first and as it is plugged - it wants to twist up if you don't pre-twist it.

The right one, once unscrewed, I did the same order as I did the left - however, where my plug was - was buried behind a crap load of tubes/wires/etc. Flat out pain in the butt. I ended having to plug it in blind using one hand while it was behind the wires/tubes because I had no real access to my plug.

Good luck!
