Well I was not talking about the sensor itself failing, just leaking oil creating a mess around it and behind it - mine is leaking and I'm replacing it. When I put in the new one, I am putting some plumbers teflon tape on the threads to help prevent leaks there too. The sensor casing can get cracked and leak out when they get older.
The sensor has a strain guage inside and oil pressing in causes a voltage change in the strain guage which is interpreted as good/bad oil pressure. I believe that as the pressure increases, resistance in the strain guage increases causing a drop in the output voltage.
If the output voltage stays too high, then the PCM senses it as a low pressure problem and the PCM trips the light. It will either come on and stay on, or flicker at you. Either way, you have to confirm/deny an oil pressure problem by putting an oil pressure guage on it and if it is OK, then you have to assume the sensor is bad.
The PCM only reads the voltage given to it from the sensor, and there is really nothing to go wrong there - unless the PCM itself is going bad - which is rare, and when they do go bad, you have more issues then oil leaks to worry about.

so Wht if its just leaking untill the level gets low enough to trip the light? I don't have time or money to put in her. I just redid the whole front brakes, even the hoses.. so I might just give up on Chrysler. my zx2 never had half the problems and I wrang it out at least once a day. I baby this and she's leaking oil. is there anywhere elce that is right ubove the center of the steering rack that could be leaking. it drips on the ground. like a drop every 3-8 sec. I'm bout to just keep dropping oil and driving her till she ****s out. Ik its Prolly not a big fix. but honesty. neons suck doggy Dick. I want my zx2 back or my 1g tibby thanks for the reply

Advance auto parts has part # S4178 BWD Oil Pressure Switch (Light) with a limited lifetime replacement warranty for $13. Teflon tape at any hardware store - $2.
A quart of oil is anywhere from $3 to $5 nowadays.
You do the math. If it is your switch, it will cost you less after just two or three quarts of oil - if that is where it is leaking.
Take it somewhere where you can put it on a rack, or equivalent setup and get under it while it is running to see where the leaking is coming from.
Take a high pressure washer with soap dispenser (like at a car wash) and try to clean off the muck first to get a better chance at finding it, just be careful and not spray your electrical components directly - especially while running, and don't spray the block directly if the engine is hot. Let it cool down first.
