If cleaning the engine does not work, replace the oil press. sending unit. These senders on Jeeps have had a history of problems where they will work one day and not the next day.

Your looking foer the oil pressure sensor on the 2004 8.1L.
You will find it located directly behind the EGR valve threaded into the block just to the drivers side of the center bolt for the transmission to block connection.

It is on the top backside of the engine block, behind the intake manifold mounted into the top of the block. You will have to lean up over the engine to see it.
