Just got word from an expert standing behind me (my son); remove the oil pressure sensor (on an I6) near the oil filter, clean it (small orifice) and put it back in. They just 'cured' one this AM.
If it doesn't work, (does 2 of 3 times) it is not an expensive part and widely available.

I have a 2002 jeep Cherokee oil gauge show max out when i start the Eng


When oil is cold, pressure will read high, but as it warms up pressure indicator should drop to normal. Are you using the correct weight oil for your weather conditions? Running straight 30 weight, or say 20w50 could cause this issue.

How do you fix check gauges light when it comes on


What are your guages reading? The CPU thinks it see's a problem.
My oil pressure would drop and my light would come on.
Oil, Charge, all could cause a check guage light.

Oil pressure gauge stays at almost max.


The oil pressure switch on a 4.0 is on the passenger side of the block toward the back near the firewall. It has a green electrical connector. Take out the sending unit look to see if there are any obstructions. I would replace it they are not exspensive they go bad all the time.

Engine light on/Oil Gauge on stays on high


Any waranties left? Is oil full? Any noises from engine? Did you put a mechanical gauge on it and check "real" oil pressure? (I would not drive it 'till I was sure about actual oil pressure!!)

Irradic reading at oil pressure guage


The sending unit would be the first thing to change, at least it would eliminate that.
