I've seen some threads that hint toward what my problem might be, but nothing specifically.
My idiot light will come on and the gauge will drop to 0 at random times while driving. It used to happen mostly when slowing down to corner or stop, but now it happens most any time. The engine does not change in the manner it runs, the temperature does not change and the oil is full and quite clean even though I am 500 away from my 3000 miles.
From what I've read from other peoples post this could be the pressure sensor, but no one has posted a problem identical to mine. I originally thought it was maybe a pump problem when it was just here and there -- but now that its happening most of the time without a change in the manner of how it runs, I'm thinking now its probably the sensor...but, since I'm new to the whole Jeep thing I want to know if anyone else has had the same problem and it ended up being something else.
Thanks in advance to everyone who helps me out!

I would guess it would be a sensor problem. If you have no oil pressure you would hear the rods knocking very quickly and your engine would not be your friend for long. I believe there is a way to clean it or just replace it and I am sure someone will chime in soon.
Before assuming the worst, replace your oil pressure sender first which is much like changing a spark plug. $30 or so from your local auto parts store though I had several bad ones in a row once so with that and other sensor issues that can be attributed to cheap Chinese imports, I tend to recommend sensors only from the dealership now. Bad oil pressure senders causing erroneous oil pressure indications are common.

Jerrys right keep it simple for now I too am having an oil pressure problem I have 110000 miles on the ruby I just bought amnd after replacing the sensor I put a mechanical gauge on it when it was warm I only had 5 lbs of oil pressure at idle (enough to keep the engine alive but not for long depending on load) so I dropped the oil pan the factory oil pump is mostly aluminum and it was worn out I am still waiting for the rest of the parts to put it back together Note here the engine sounded fine and after removing the con rod bearings they showed normal wear the mechanical gauge was less than 20 dollars it will tell you the real story ( I hooked mine up temporary and was able to compare it to the custer gauge a little scary to see good luck with it.
For my own peace of mind, I had my oil pressure versus RPMs checked and a new sensor installed. I had my Jeep in the shop for other reasons and this was just a by-the-way deal. My oil pressure was fine at all RPMs. After they installed the new sensor, it worked great for about a month.....then it started the BS all over again. I have seen many, many similar write-ups on oil pressure on here and have never seen one instance of engine damage due to low oil pressure.
My question is, the Jeep people are bound to know about this problem with TJs. Why isn't it addressed and fixed?
