Jeep Check Gauges Light

My 05 TJ has been lighting up the check gauges light for a little while now. Once the light pops up the oil pressure will go down then go back up to normal. Sometimes it stays on zero and the check gauge light is on for a while when I’m driving but will go off in a little and other times it is really quick and it goes back to normal. I have no clue what’s going on with it. Any ideas?

I have the same exact problem with my 2005 LJ. I am going to take it to the dealership at sometime. I researched and it sounds like a sensor.
