Re: High Oil Pressure Reading - Sending Unit?
If this vehicle is set up the same as my 00Cherokee you can check the dash
panel by turning the key to start (do not start the vehicle), and hold in the
trip reset button.(about 5 seconds) It will go into diagnostic mode.Gages will
read 20/40/60/80 and then return to 0. If the gage is fine disconnect the
sender and check for 5Volts at the connector. The ground should be fine as it
is shared with other sensors which are working fine.The problem could be the
sensor($30?)or in the PCM which sends the signal to the gage.

Re: High Oil Pressure Reading - Sending Unit?
Thanks for all the feedback, everyone!
A little more info - on Wednesday when it happened, we had temps in the
low 30s - cold enough for a couple of inches of snow to stick, and some
wind. (This is Dallas area, Texas). I forgot to mention that I
checked the oil when this started on Wednesday night, and it was full,
clear, and normal thickness.
We went out of town for the holidays and I just picked the Jeep back
up. It's in the 40s right now, and the oil pressure is still reading
high, but is not maxed out.
So I figure I'll grab an oil filter on the way home and give that a
shot. Means I get to use some of the new tools I got for Christmas!
