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

 

Oil pressure sending unit, just had to buy one for 35 bucks. The unit is near the oil filter.

 

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.

 

Thanks

 

also check your GROUND wire going from the block to firewall this could sind a bad ground and cause gages to go wacky

 

Shanks.

 

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.

 

Good to know!

 

If you move the wire going to the pressure unit it will drop back down
