Oil Pressure gone wack!
My pressure is NOT way up there...how could I possibly fix this? It's not really a big issue to me but sometimes it bugs me when the gauge slaps up and down and tries to get an actual reading and fails and falls way up there. lol

mine would do this occasionally after I changed my oil filter, but it wasn't the sensor. At some point the rubber insulator thingamagig around the pressure sensor wiring connector that kept the connector from moving around was...missing, so the wire wasn't getting a good connection. Try wiggling the connector a bit and see if it goes back down.

Almost assuredly related to the oil pressure sending unit as already mentioned. Could be connectivity or the sending unit itself; they are a common fail.
If you end up buying one, buy it from Jeep for the best reliability/longevity/mating with your factory oil pressure gauge. Well worth a few extra bucks.
